Main points
Since NHS Test and Trace launched (28 May to 14 October):
101,494 people tested positive for coronavirus (COVID-19) at least once[footnote 1] in England between 8 October and 14 October. Positive cases have been rising steeply since the end of August and in the latest week there has been an increase of 12% compared to the previous week. 7.1% of people tested had a positive result; this rate has been increasing since the end of August, when the positivity rate was 0.9%.
1,422,112 people were tested at least once for COVID-19[footnote 1], a 12% increase from the previous week and continuing the upward trend seen since the end of June. A total of 8,934,753 people have been tested at least once since Test and Trace began.
Turnaround times for pillar 2 (swab testing for the wide population) have become longer for all in-person testing routes[footnote 2] compared to the previous week.
In the most recent week, 33.4% of in-person tests results were received the next day after the test was taken. Turnaround times for satellite/home tests remain broadly similar to the previous week.
The median distance to in-person testing sites (pillar 2) for booked tests has decreased over the past month. Between 8 October and 14 October, the median distance has decreased to 2.9 miles from 3.2 miles in the previous week.
96,521 people were transferred to the contact tracing system between 8 October and 14 October. The number of people transferred has been increasing steeply over the past 6 weeks with over 10 times as many people being transferred in the most recent week compared to the beginning of September.
Of those transferred to the contact tracing system between 8 October and 14 October, 80.7% were reached and asked to provide information about their contacts. This has declined since the beginning of September but increased slightly over the past two weeks.
251,613 people were identified as coming into close contact with someone who had tested positive between 8 October and 14 October. This is an increase of 15% compared with the previous week, continuing the sharp upward trend since the end of August. For those where communication details were available, 75.1% were reached and asked to self-isolate. Taking into account all contacts identified, 59.6% were reached.
For coronavirus (COVID-19) testing in the UK:
Testing capacity in the UK across all pillars between 8 October and 14 October was at 3,083,306 tests, a slight increase of 2% compared to the previous week. Testing capacity for all swab testing[footnote 3] was at 2,235,606 tests, a 34% increase since the start of September.
884,583 tests were sent out across the UK within pillar 2 in the latest week. The number of tests sent out has been gradually increasing since mid-August but has decreased over the past two weeks.
1,884,111 tests were processed in the UK, across all pillars, in the latest week, consistent with the previous week. Since the beginning of September there has been a 33% increase in tests processed. 1,858,501 swab tests were processed in the latest week, which is over 3 times higher than in mid-June.
Introduction
The Department for Health and Social Care (DHSC) publishes weekly statistics on NHS Test and Trace (England) and coronavirus (COVID-19) testing in the UK, across all 4 testing pillars.
From 15 October, a new methodology for the number of people tested each week and number of people testing positive each week has been introduced, which allows a weekly positivity rate to be calculated.
The purpose of this publication is to provide a weekly update on the implementation and performance of NHS Test and Trace in England and Testing in the UK.
For NHS Test and Trace (England), this includes:
Testing
- people tested for coronavirus (COVID-19), England
- people testing positive for coronavirus (COVID-19) and weekly positivity rate, England
- time taken for test results to become available, England
- distance travelled to take a test in-person, England
Contact tracing
- people transferred to the contact tracing system, and the time taken for them to be reached, England
- close contacts identified for complex and non-complex cases, and the time taken for them to be reached, England
For NHS COVID-19 app (England and Wales), this includes:
- number of downloads
- number of QR posters generated
For coronavirus (COVID-19) testing in the UK, this includes:
- lab testing capacity, UK
- number of tests sent out, UK
- number of tests processed, UK
Data collected for NHS Test and Trace is primarily for operational purposes and was not designed to track the spread of the virus. Studies into the spread of the virus in the UK are carried out by the Office for National Statistics (ONS). Further guidance can be found in comparing methods used in the COVID-19 Infection Survey and NHS Test and Trace, England.
A list of data sources relating to the coronavirus pandemic in the UK can be found at coronavirus (COVID-19) statistics and analysis. A breakdown of all available testing and contact tracing data in the UK can be found at testing and contact tracing in the UK: summary of data.
A full explanation of the data sources and methods used to produce these statistics can be found in the additional methodology document for NHS Test and Trace statistics.
Revisions to figures previously published
Figures given in previous releases are routinely revised for:
- people tested for coronavirus
- people testing positive for coronavirus
- pillar 2 testing turnaround times
- distance to in-person test sites
- contact tracing
- cumulative figures for coronavirus testing in the UK
Figures for pillar 1 testing turnaround times are not routinely revised as only minor changes occur to past weeks post publication. Figures are only revised when substantial changes occur. More detail on routine revisions is given in the quality section.
Note that these routine revisions to data includes the local authority level contact tracing data that is made available on the weekly collection page. As past data is revised, subtracting figures given in the previous week from figures given in the current week will not give the total number of cases for that week.
NHS Test and Trace
NHS Test and Trace was launched in England on 28 May and ensures that anyone who develops symptoms of coronavirus (COVID-19) can quickly be tested to find out if they have the virus. It then helps trace recent close contacts of anyone who tests positives for coronavirus and, if necessary, notifies them that they must self -isolate at home to help stop the spread of the virus. The flow of how people move through the NHS Test and Trace service is shown in Figure 1. More information about NHS Test and Trace can be found at NHS Test and Trace: how it works.
Testing in England
NHS Test and Trace starts with an individual taking a swab test, either in pillar 1 (testing in hospitals and outbreak locations), pillar 2 (national swab testing) or pillar 4 (prevalence studies). Those who go on to test positive will have their case transferred to NHS Test and Trace for contact tracing.
NHS Test and Trace is for England only, therefore the figures in this section are given for England. Figures for UK testing are given in the coronavirus (COVID-19) testing in the UK section and information on contact tracing in Scotland, Wales and Northern Ireland can be found directly from Public Health Scotland, the Welsh government and the Northern Ireland Public Health Agency.
Figure 1: flowchart showing how people move through NHS Test and Trace
The diagram shows the journey a person can take through NHS Test and Trace. For pillar 1, this starts with a person having a coronavirus test in hospital. For pillar 2, this starts with a person booking or ordering a coronavirus test. Pillar 2 tests can be either be conducted at a regional test site or mobile test unit; or a satellite or home test can be conducted. For pillar 4, this starts with a person having a coronavirus test as part of a prevalence study. After tests have been taken, they are sent to a laboratory for processing. Once processed, a person will be emailed or texted their result.
If a person has a positive COVID-19 test result, then their case is transferred to NHS Test and Trace and can be managed in one of 2 ways. First, non-complex cases are reached either online or by a call centre. They are then asked to provide details of recent close contacts. These recent close contacts are then reached by NHS Test and Trace and advised to self-isolate. Second, complex cases are escalated to local health protection teams who work to identify and reach recent close contacts and advise them to self-isolate.
Additionally, if the person has the app and used the app to book their test, their positive result is updated automatically. If they have the app but booked their test via a different route then they can use a link to add their positive result to the app. Once their positive result is entered into the app, the person is asked if they are willing to share their data and if they say yes, the app identifies other app users who have been in close contact with the person who has tested positive. Close contacts then receive an app notification to self-isolate.
People tested, England
Between 8 October to 14 October, 1,422,112 people were tested for coronavirus (COVID-19) at least once in the reporting week[footnote 4], a 12% increase from the previous week. Since Test and Trace launched 8,934,753 people have been tested at least once[footnote 5].
Since 15 October, the number of people tested in a reporting week has been deduplicated for the respective week. Reports before this date reported on the number of people newly tested and newly tested positive each week based on deduplication since testing began. See NHS Test and Trace statistics methodology for more information.
The number of people tested in each reporting week has been gradually increasing since the end of June with a larger increase seen between the last week in August and first week in September. The number of people tested between 8 October to 14 October has increased by 55% since the end of August. Over the same time period, there has been a 32% increase in the number of people tested under pillar 1 (testing in hospitals and outbreak locations) and a 66% increase under pillar 2 (national swab testing). A breakdown of the number of people tested in each reporting week by age and gender is also available in the weekly collection page.
Since Test and Trace launched at the end of May, 8,934,753 people have been tested at least once[footnote 6], of which 69.1% were tested under pillar 2 and 30.9% under pillar 1.
Figure 2: number of people tested for COVID-19 in each reporting week by pillar, England
The data for the most recent weeks can be found in the annex, table 1.
Between 8 October and 14 October, 101,494 people tested positive in the latest reporting week[footnote 6]. This is 7.1% of people tested during this week. The number of positive cases and percentage of people testing positive has been steeply rising since the end of August.
The number of people testing positive between 8 October and 14 October increased by 12% compared to the previous week. This increase continues the upward trend in positive cases first observed at the end of August. There are 8 times as many positive cases identified in the most recent week compared to the end of August.
The percentage of people tested who tested positive in the first week of Test and Trace was 2.8% and this steadily declined until the end of August. The weekly positivity rate has increased since the end of August, increasing from 0.9% between 20 August and 26 August to 7.1% in the most recent week.
A breakdown of the number of people testing positive in each reporting week, by age and gender is also available in the weekly collection page. These breakdowns include positivity rate by age and gender.
Since Test and Trace launched, 388,369 people have tested positive for COVID-19[footnote 7] at least once[footnote 5]. 86.9% of these positive cases were tested under pillar 2 in comparison to 13.1% under pillar 1[footnote 8].
Figure 3: number of people testing positive for COVID-19 in each reporting week by pillar, England
The data for the most recent weeks can be found in the annex, table 1.
Figure 4: percentage of people testing positive for COVID-19 in each reporting week, England
The data for the most recent weeks can be found in the annex, table 1.
Pillar 1 testing turnaround times, England
Some pillar 1 tests are conducted in a hospital setting, and it is therefore not practical for those administering the tests to record the exact time that a test was taken. Therefore, the time taken to receive a coronavirus (COVID-19) test result is measured from the time that a test is received by a laboratory for processing to the time when the results are published to the Laboratory Information Management System (LIMS).
The total tests given in figures for pillar 1 turnaround times is not the same as the number of tests processed in pillar 1 as study samples and tests from private laboratories do not report data on turnaround times. This data is only available from 9 July. More details can be found in the NHS Test and Trace statistics methodology.
Over 4 out of 5 pillar 1 test results were made available within 24 hours of the laboratory receiving the test. This proportion has remained similar since reporting began on 9 July.
Between 8 October and 14 October, 86.9% of pillar 1 test results were made available within 24 hours.
Figure 5: number of pillar 1 test results by whether they were made available within 24 hours of the laboratory receiving the test, England
The data for the most recent weeks can be found in the annex, table 2.
Pillar 2 testing turnaround times, England
There are various routes for getting tested within pillar 2 (national swab testing). Data on the time taken to receive a COVID-19 test result for pillar 2 is split up to reflect this, as this impacts on the turnaround times[footnote 9]. These routes include:
- regional test sites, which includes drive-through testing centres
- local test sites[footnote 10], which are similar to regional test sites but specifically for walk ups
- mobile testing units, which travel around the UK to increase access to COVID-19 testing. They respond to need, travelling to test people at specific sites including care homes, police stations and prisons
- satellite test centres, which includes test kits provided directly to ‘satellite’ centres at places like hospitals or care homes that have a particularly urgent or significant need
- home test kits, which are delivered to someone’s door so they can test themselves and their family without leaving the house
Turnaround times are measured and reported in 2 ways, time taken from booking a test and from taking a test to receiving a test result. More information on these definitions is in the terminology section. Both measures are now reported as the median turnaround time, in addition to the usual turnaround time windows, such as within 24 hours. All these measures are available in full in the accompanying data tables, however only time from taking a test is discussed below.
The total tests reported for pillar 2 turnaround times is not the same as the number of tests processed in pillar 2 as test processed is available for the UK (rather than for England only). In addition, they are reporting on the number of tests at different stages in the process. Further detail is given in the NHS Test and Trace statistics methodology.
After someone takes a test, it is transported to a laboratory for processing. There are normal fluctuations in this operational process which can sometimes cause the time taken to receive a test result to go over 24 hours, but still be turned around the next day. Where appropriate therefore we also provide the number of tests turned around the day after a test was taken.
Satellite tests are predominantly used by care homes who need greater control and flexibility over when test kits are collected. For example, tests may be conducted over multiple days with a collection scheduled a few days later. Home test kits take time to be posted to a person and be couriered back to the lab. Consequently, a low proportion of home and satellite test results will be available within 24 hours of the test being taken.
The median time to receive a test result after taking a test in-person has increased in the latest week.
In the first month of Test and Trace, there was an initial reduction in the median time taken to receive a test result for in-person tests (regional test sites, local test sites and mobile testing units). This began to gradually trend back up from the start of July until the middle of September.
Between 8 October and 14 October, the median time taken to receive a test result at regional test sites increased to 45 hours from 28 hours in the previous week. Similarly, local test sites increased to 47 hours from 29 hours and mobile testing units also increased to 41 hours from 26 hours during the same period.
The median time taken to receive a test result after taking a test has decreased for both home testing kits/satellite test centres since their peak at the beginning of September. However, the median time for home testing kits has increased over the past 3 weeks.
In the first month of Test and Trace, home testing kits and satellite test centres saw an initial reduction in the median time taken to receive a test result followed by an increase from the end of July until the beginning of September.
Since the beginning of September, the median time taken to receive a test result from satellite test centres has decreased overall from 102 hours to 59 hours in the latest week. The median time for home testing kits has also decreased from 83 hours at the beginning of September to 56 hours in mid-September. However, the median time has since increased and is now at 78 hours in the latest week.
Figure 6: median time (hours) from taking a test to receiving test results by route, England
The data for the most recent weeks can be found in the annex, table 3.
The percentage of test results received within 24 hours for in-person tests has decreased in the latest week and has decreased steeply since the end of June. The percentage received within 48 hours for home testing kits and satellite test centres remains consistent compared to the previous week.
In the most recent week, for in-person tests (local test sites, mobile testing units and regional test sites), 15.1% were received within 24 hours compared to 32.8% in the previous week. There has been a downward trend in the percentage of in-person test results received within 24 hours since the end of June when 94.3% were received within this time frame. 20.1% of test results were received within 48 hours for home test kits and satellite test centres, compared to 19.5% in the previous week.
For all routes combined, 7.4% of tests from all test sites were received within 24 hours of a test being taken compared to 14.8% in the previous week. If we consider the day the test was taken, 33.4% of in-person tests results were received the next day after the test was taken and 18.4% for all routes combined.
For satellite test centres, 72.7% were received within 72 hours compared to 66.9% in the previous week. 84.5% satellite tests were received within 3 days after the day was taken. In the most recent week, approximately 99% of tests from satellite test centres were care home tests, removing the 1% from other sites does not substantially change the turnaround figures.
Table 1: percentage of results received within 24 hours (in-person tests) or within 48 hours (home/satellite tests), by route, England
| 1 Oct to 7 Oct: percentage of tests | 8 Oct to 14 Oct: percentage of tests | Since Test and Trace launched. 28 May to 14 Oct: percentage of tests | |
|---|---|---|---|
| Regional test sites within 24 hours | 32.9% | 13.5% | 54.4% |
| Local test sites within 24 hours | 24.4% | 10.5% | 26.3% |
| Mobile testing units within 24 hours | 42.4% | 21.5% | 52.8% |
| Satellite test centres within 48 hours | 21.1% | 22.3% | 23.9% |
| Home testing kits within 48 hours | 16.0% | 14.7% | 31.3% |
The data for the total number of tests across the most recent weeks can be found in the annex, table 4.
Distance to in-person testing sites for booked tests, pillar 2, England
The distance to testing sites for booked tests at is calculated as the direct distance between the approximate centre of a person’s postal district and their chosen test location in straight line. This is reported as the median and associated percentiles for those who successfully booked a test at regional test sites, local test sites and mobile testing units in the latest week. More information is available in the NHS Test and Trace statistics methodology.
The median distance to in-person testing sites for booked tests has continued to decrease over the past month.
From mid-August to mid-September, the distance to testing sites for booked tests had increased across in-person routes. This has since decreased over the past 4 weeks. Between 8 October and 14 October, the median distance to an in-person test site decreased to 2.9 miles from 3.2 miles in the previous week. 90% of people who booked a test at a test centre lived 11.8 miles or less away.
Considering each route individually, in the latest week the median distance to testing sites for booked tests at regional test sites has decreased to 5.0 miles from 5.7 miles. For local test sites, this decreased to 1.4 miles from 1.7 miles and for mobile testing units the median decreased to 3.0 from 3.7, compared to the previous week.
Figure 7: median distance (miles) to testing sites for tests booked at an in-person test site by route, England
The data for the most recent weeks can be found in the annex, table 5.
Contact tracing in England
Once a person has a confirmed positive test result for coronavirus[footnote 11], this person is transferred to NHS Test and Trace and a case is opened for them. The number of positive cases transferred to the contact tracing system may not always align with the number of people testing positive for COVID-19. There are several reasons for this which are outlined in the information for users document.
Positive cases transferred to NHS Test and Trace are handled in different ways depending on their complexity. Positive cases linked to potential outbreaks in specific settings are handled by PHE local health protection teams, these are termed complex cases, whereas those managed more generally by online and call centre capacity are termed non-complex cases. Further information is available in the NHS Test and Trace statistics methodology.
Positive cases transferred to NHS Test and Trace
In the latest week almost 12% more people were transferred to the contact tracing system compared to the previous week, a continuation of the sharp upward trend seen from the end of August.
Between 8 October and 14 October, 96,521 people were transferred to the contact tracing system. The number of people transferred has been increasing steeply over the last 6 weeks and in the latest week, is over 10 times higher than the end of August.
Between 8 October and 14 October, more than 4 in every 5 people transferred to the contact tracing system were reached and asked to provide information about their contacts.
Out of the 96,521 people transferred to the contact tracing system in the latest week, 77,892 (80.7%) were reached, 17,141 (17.8%) were not reached and 1,488 (1.5%) had no communication details. The proportion of people reached has decreased since the beginning of September but has increased slightly in the latest week. Since Test and Trace launched, 79.5% of all cases have been reached.
In the latest week, 1,796 people, who were reached and asked to provide details of close contacts, were classified as complex cases whereas 76,096 people were classified as non-complex. For more information on the different categories of cases and the outcomes of contact tracing see the terminology section.

| 1 Oct to 7 Oct: number of people (percentage) | 8 Oct to 14 Oct: number of people (percentage) | Since Test and Trace launched. 28 May to 14 Oct: number of people (percentage) | |
|---|---|---|---|
| People who were reached and asked to provide details of recent close contacts | 68,856 (79.9%) | 77,892 (80.7%) | 290,034 (79.5%) |
| People classified as non-complex | 66,748 | 76,096 | 274,291 |
| People classified as complex | 2,108 | 1,796 | 15,743 |
| People who were not reached | 15,995 (18.6%) | 17,141 (17.8%) | 67,336 (18.4%) |
| People whose communication details were not provided | 1,357 (1.6%) | 1,488 (1.5%) | 7,673 (2.1%) |
| Total | 86,208 | 96,521 | 365,043 |
Proportion of people transferred to the contact tracing system who were reached by upper tier local authority (UTLA)
Figure 9: percentage of cases reached and asked to provide details of recent close contacts by UTLA since Test and Trace began
This data is available to download as a csv on the weekly publication collection page[footnote 13].
In the latest week more than 4 in every 5 people who were reached and asked to provide information about their contacts, provided one or more close contacts.
Out of the 77,892 people reached between 8 October and 14 October, 66,138 (84.9%) provided details of one or more close contacts. This continues the upward trend in the proportion of people providing one or more contacts since mid-August.
The number who were not able to give any recent close contacts refers to people who were successfully reached by NHS Test and Trace, but either had no recent close contacts or could not provide details of close recent contacts to pass on for further contact tracing (for example, recent close contact with strangers on the bus).
In the most recent week, the median number of complex contacts provided per case remains at 5, consistent with the previous week. For non-complex cases the median was 3 and this has been approximately constant since the start of Test and Trace.
Figure 10: proportion of people transferred to the contact tracing system (includes complex and non-complex cases) who were reached and asked to provide details of recent close contacts by whether they provided details for contacts or not, England
The data for the most recent weeks can be found in the annex, table 6.
The proportion of cases who were reached by the phone or online has remained broadly consistent since test and trace began. However, in the latest week the proportion reached by phone rather than online has notably increased.
Of the non-complex cases reached between 8 October and 14 October, 19,333 (25.6%) were reached online and 56,282 (74.4%) were reached via the phone. The proportion of cases reached online has increased from 22.2% in the previous week, and consequently the proportion reached by phone has decreased from 77.8% in the same period. Since Test and Trace began, 30.4% were reached online and 69.6% were reached by phone.
Most cases are offered the online route initially and are followed up with phone call if they have not been reached online. For more information on how cases are contacted see NHS Test and Trace statistics methodology page.
For non-complex cases, over half were reached and asked to provide details about recent close contacts within 24 hours of their case being transferred to contact tracing.
Between 8 October and 14 October, 54.3% of people (41,288) were reached within 24 hours. The proportion of people reached within 24 hours has been declining over the past 5 weeks. Since Test and Trace launched on 28 May, 61.1% of people (167,630) have been reached within 24 hours.
Note that because these timing statistics are from when a case was transferred to the contact tracing system, delays in transferring cases to contact tracing will not be captured in these figures.

The data for the most recent weeks can be found in the annex, table 7.
Close contacts identified by NHS Test and Trace
In the latest week, the number of contacts identified increased by 15% compared to the previous week. This continues the sharp upward trend seen since the end of August.
Between 8 October and 14 October, 251,613 people were identified as recent close contacts, of which 238,093 (94.6%) were non-complex and 13,520 (5.4%) were complex. The number of non-complex contacts identified in the most recent week is more than 9 times higher compared to the end of August. This is in comparison to complex contacts identified which have increased by 67% over the same time period.
The total number of complex close contacts identified had a steep decline between the start of contact tracing and the end of June, in comparison to the number of non-complex contacts which remained broadly consistent over the same time period. At the beginning of June complex contacts were 81.7% of contacts identified compared to only 5.4% in the most recent week.
As non-complex cases have a higher proportion of contacts who are unable to be reached, this has contributed to the reduction in the overall percentage of contacts who were reached and asked to self-isolate since Test and Trace launched, from 91.1% to 59.6% in the latest week.
Considering only the contacts where communication details were provided, 75.1% were reached and asked to self-isolate in the most recent week. Since Test and Trace launched, this is 82.3%.
Figure 12: number of people identified as recent close contacts, England
The data for the most recent weeks can be found in the annex, table 8.
The percentage of non-complex contacts who were reached and asked to self-isolate has decreased over the past 3 weeks and is at 57.6% reached in the latest week.
Between 8 October and 14 October, 238,093 non-complex close contacts were identified of which 137,102 (57.6%) were reached and asked to self-isolate. This percentage increased between the end of August and mid-September but has declined over the past 3 weeks.
In the latest week, 49,072 (20.6%) non-complex contacts were not reached and 51,919 (21.8%) people had no communication details. For more information on the different outcomes of contact tracing see the terminology section.
Almost all complex contacts continue to be reached and asked to self-isolate.
Between 8 October and 14 October, 13,520 complex close contacts were identified of which 12,821 (94.8%) were reached and asked to self-isolate and 699 (5.2%) were not reached. Since Test and Trace launched 97.4% of all complex contacts have been successfully reached.

Proportion of non-complex close contacts identified who were reached and asked to self-isolate by upper tier local authority
Figure 14: percentage of non-complex contacts reached and asked to provide details of recent close contacts by UTLA since Test and Trace began
This data is available to download as a csv on the weekly publication collection page[footnote 13].
In the most recent week, more than 2 out of 3 non-complex contacts were from the same household as the case they were identified from.
The proportion of non-complex close contacts from the same household as the case they were identified from steadily declined between the end of May, when Test and Trace launched, and the beginning of September. Between 8 October and 14 October, 72.4% of non-complex contacts were household contacts, a continuation of the gradual increase since the beginning of September.
In the latest week, 55.6% of these household contacts were successfully reached and asked to self-isolate. This is in comparison to 62.8% for non-complex contacts who were from a different household to the case from which they were identified.
It is likely that cases often advise their household members to self-isolate in advance of these contacts being directly contacted by contact tracers. Therefore, even where household contacts are recorded as not reached and advised to self-isolate, they may already be aware of their exposure and isolating appropriately. This may be a contributing factor to a lower proportion of household contacts being reached in comparison to non-household contacts.
Figure 15: proportion of recent close non-complex contacts by whether they were from the same household as the case that they were identified from, England
The data for the most recent weeks can be found in the annex, table 9.
The proportion of contacts who were reached by the phone or online has remained broadly consistent since Test and Trace began. However, in the latest week the proportion reached by phone rather than online has notably increased.
Of the non-complex contacts reached between 8 October and 14 October, 38,801(28.3%) were reached online and 98,300 (71.7%) were reached via the phone. The proportion of contacts reached online and by phone has generally remained consistent since Test and Trace began. However, in the past two weeks the proportion reached online has been decreasing. Since Test and Trace began, 40.6% of non-complex contacts were reached online and 59.4% were reached by phone.
Most contacts are offered the online route initially and are followed up with phone call if they have not been reached online. For more information on how cases are contacted see NHS Test and Trace statistics methodology page.
For non-complex contacts who were advised to self-isolate, more than 3 out of 5 were reached within 24 hours of being identified[footnote 14].
Between 8 October and 14 October, 62.9% of non-complex contacts that were advised to self-isolate were reached within 24 hours of being identified. This proportion remained broadly similar from the start of Test and Trace until mid-September. However, in the last 3 weeks there has been a notable decrease. Overall, since Test and Trace launched, 70.7% of all non-complex contacts have been reached and advised to self-isolate within 24 hours.
For non-complex contacts who were advised to self-isolate, 31.8% were reached within 24 hours of the case that reported them being transferred to the contact tracing system.
Between 8 October and 14 October, 43,488 (31.8%) non-complex contacts were reached and advised to self-isolate within 24 hours of the case that reported them being transferred to the contact tracing system. This has seen an overall decline from a peak of 67.3% at the beginning of June and a notable decrease in the past 3 weeks.
This measure gives a sense of the end-to-end journey time through the Test and Trace system from when an individual testing positive was reported to Test and Trace, to when their close contacts were reached and advised to self-isolate.
Note that because these timing statistics are from when a case was transferred to the contact tracing system, delays in transferring cases to contact tracing will not be captured in these figures.

NHS COVID-19 app in England and Wales
The NHS COVID-19 app has been widely available to download since 24 September and provides a number of tools to support testing and contact tracing in England and Wales including contact tracing, local area alerts and venue check-in.
The NHS COVID-19 app complements NHS Test and Trace processes by extending the speed, reach and precision of contact tracing. It allows close contacts unknown to the individual who has tested positive, for example strangers on public transport, to be notified to self-isolate, if they are also an app user.
Since the app is anonymous and voluntary, NHS Test and Trace contact tracers will not know whether someone who tests positive is an app user or whether the contacts they identify are app users. All positive cases, regardless of whether they are an app user, will be contacted by NHS Test and Trace and asked to provide details of recent, close contacts. Contacts will all be notified by NHS Test and Trace so may be notified by both the app and NHS Test and Trace. See NHS COVID-19 app for more information.
The NHS COVID-19 app covers England and Wales only. For information on contact tracing apps in Scotland and Northern Ireland see Protect Scotland and StopCOVID NI.
Prior to national release on the 24 September, the app was available to download from 13 August for those involved with the pilot. The data below includes data from the pilot period, as well as after the main launch.
As of 14 October, the app has been downloaded 17,679,872 times and 684,449 QR posters have been generated through the GOV.UK coronavirus QR poster service. These figures cover both England and Wales.
Coronavirus (COVID-19) testing in the UK
Statistics on coronavirus testing in the UK, across all 4 testing pillars are also included in this release. This includes details on laboratory testing capacity (lab capacity), number of tests sent out and number of tests processed since the start of testing in the UK. Definitions of the testing pillars and swab and antibody tests can be found in the terminology section.
This data was previously published on daily statistics on coronavirus cases in the UK until Thursday 20 August. Although this page is no longer be updated the historic UK testing statistics and the accompanying COVID-19 testing data methodology note are still available. Statistics on tests processed and testing capacity are published weekly in this publication and daily figures are also available on the coronavirus in the UK dashboard. Statistics on positive cases will continue to be published daily on the dashboard and weekly in the NHS Test and Trace publication. A historic time series of weekly lab capacity, tests sent out and tests processed is available on the collection page for this release.
Testing capacity in the UK, pillars 1 to 4
Coronavirus tests are processed in several separate labs. Projected lab capacity is an estimate of each lab’s constrained capacity each day based on the staff, chemical reagents and other resources it has available. These estimates are made locally by the labs themselves. Actual capacity is calculated retrospectively after knowing what the exact conditions were on the day and how many tests could have theoretically been processed. The figures in this bulletin refer to projected capacity. Further information on the methods for determining capacity is available in the NHS Test and Trace statistics methodology.
Testing capacity between 8 October to 14 October was 3,083,306 tests, a slight increase of 2% compared with the previous week, primarily driven by an 8% increase in pillar 2 testing capacity. This continues the gradual increase in testing capacity seen over the past month. Testing capacity gradually increased from around 45,000 tests at the end of March to over 2,400,000 in mid-July when capacity levelled off until mid-August.
Swab testing capacity is at 2,235,606 tests which is a 34% increase since the start of September. In comparison, antibody testing (serology) capacity has remained consistent over the same time period.

A breakdown of the daily lab capacity for swab and antibody tests, up to the 22 September is available on the NHS Test and Trace collection page. Further information is available in the NHS Test and Trace statistics methodology.
Number of tests sent out in the UK, pillar 2 and pillar 4
Tests can be administered in different ways:
- tests taken at a hospital
- mobile testing unit
- regional testing sites
- tests sent out to individuals at home or satellite locations
Tests sent out are only available as part of pillar 2 (swab testing) and pillar 4 (swab and antibody testing). Not all tests sent out will be returned.
It is not currently possible to compare the total number of tests sent out with the total number of tests processed in pillar 2 and pillar 4, as given in table 5a. This is because tests sent out includes only tests sent to individuals at home or to satellite testing locations, while tests processed includes all tests that have remained within the control of the programme (and were counted at the time at which processed in labs) and those that have been sent out and subsequently returned to be processed in a lab. Further information is available in the NHS Test and Trace statistics methodology.
884,583 tests were sent out across the UK within pillar 2 between 8 October and 14 October, during the same period no tests were sent out under pillar 4. The number of tests sent out increased from mid-August until mid-September but has decreased by 29% over the past 2 weeks. Overall, the number of tests sent out has seen an upward trend since mid-April when there were less than 1,000 tests sent out compared to over 880,000 in the latest week.
Table 4: number of tests sent out, pillars 2 and 4, UK
| 1 Oct to 7 Oct: number of tests | 8 Oct to 14 Oct: number of tests | Total since data collection began: number of tests | |
|---|---|---|---|
| Pillar 2 | 1,003,470 | 884,583 | 15,831,639 |
| Pillar 4 | 0 | 0 | 1,721,056 |
| UK total | 1,003,470 | 884,583 | 17,552,695 |
Number of tests processed in the UK, pillars 1 to 4
The number of tests processed counts all tests that have remained within the control of the programme (and were counted at the time at which processed in labs) and those that have been sent out and subsequently returned to be processed in a laboratory. They are counted at the time at which they were processed. This measure shows how many tests have been processed, including both swab testing (pillar 1, pillar 2 and partial pillar 4) and antibody testing (pillars 3 and 4). Further details are available in the NHS Test and Trace statistics methodology.
For pillars 1 and 2, the number of tests processed in a laboratory is different to the number of test results processed which is reported as part of the Test and Trace testing turnaround times for England. This is because they are reporting on the number of tests at different stages in the process as well as reporting different geographies (UK and England) and because some tests are excluded from the turnaround time counts.
Between 8 October and 14 October, 1,884,111 tests were processed in total across pillars 1 to 4, this is consistent with the previous week however is a 33% increase since the beginning of September. The number of tests processed has gradually increased from around 13,000 at the end of March to over 1.8 million in the most recent week.
In the current week, 1,858,501 swab tests were processed, this is consistent with the previous week however is over 3 times higher than mid-June. The number of antibody (serology) tests processed have remained at relatively low levels with a peak in mid-June, and the number of tests have been decreasing over the past 3 weeks.

Terminology
Testing
Pillar 1 testing: swab testing in Public Health England (PHE) labs, NHS hospitals for those with a clinical need, and health and care workers.
Pillar 2 testing: swab testing for the wider population, through commercial partnerships[footnote 17], carried out through several different routes:
- regional test sites, which includes drive-through testing centres
- local test sites[footnote 10], which are similar to regional test sites but specifically for walk ups
- mobile testing units, which travel around the UK to increase access to COVID-19 testing. They respond to need, travelling to test people at specific sites including care homes, police stations and prisons
- satellite test centres, which includes test kits provided directly to ‘satellite’ centres at places like hospitals or care homes that have a particularly urgent or significant need
- home test kits, which are delivered to someone’s door so they can test themselves and their family without leaving the house
Pillar 3 testing: serology testing to show if people have antibodies from having had coronavirus.
Pillar 4 testing: blood and swab testing for national surveillance support by PHE, ONS and research, academic and scientific partners to learn more about the prevalence and spread of the virus and for other testing research purposes.
Swab testing: testing using polymerase chain reaction (PCR) assay within pillars 1, 2 and pillar 4 to show if someone currently has COVID-19.
Antibody testing: testing of a blood sample within pillar 3 and pillar 4 to show if people have antibodies from having had COVID-19.
People tested each week: refers to people who have been tested at least once in each reporting week, therefore if someone had multiple tests in a given week they would be counted once.
People testing positive each week: refers to the number of people who tested positive at least once in each reporting week, therefore is someone tested positive multiple times in a given week they would only be counted once.
Weekly positivity rate: the number of people testing positive as a proportion of the number of people tested in each reporting week.
Cumulative people tested: refers to the number of people who have been tested at least once since Test and Trace launched.
Cumulative people testing positive: refers to the number of people who have tested positive at least once since Test and Trace launched.
For pillar 2, there are two measures of the time taken to receive a coronavirus (COVID-19) test result:
- the time taken to receive a COVID-19 test result from time of booking is measured from the time that a person books an appointment on the website to the time when the person receives a notification of their test result via an email or an SMS. This data is only available for regional test sites, local test sites and mobile testing units, as test booking and registration processes for home testing and satellite test centres are currently undertaken on different systems
- the time taken to receive a COVID-19 test result from time of test is measured from the time a person completes a test registration (or the time a person indicates their test was taken for home testing kits) until the time that they receive a notification of the result of their test via an email or an SMS
Tracing
NHS Test and Trace has 2 ways of handling cases depending on their complexity:
Complex cases and contacts
PHE local health protection teams manage cases linked to outbreaks, examples include someone who works or has recently visited:
- a health or care setting, such as a hospital or care home
- a prison or other secure setting
- a school for people with special needs
- critical national infrastructure or areas vital for national security
Non-complex cases and contacts
Wider online and other call centre capacity for less complex cases.
When a case is transferred to NHS Test and Trace contact tracers will attempt to contact the individual which results in one the following 3 outcomes:
- Reached and provided information about recent close contacts: contact tracers successfully reached the individual and asked them to provide details for recent close contacts
- No communication details provided: people who had no communication details provided are those who were transferred to NHS Test and Trace but did not have any associated contact details (for example, phone number or email address).
- Not reached: The number of people who were not reached includes those people who the service has been unable to reach because there has been no response to text, email and call reminders. It also includes people who were reached but declined to give details of close contacts. There may also be a small number of people who have not been reached but where contact tracers are still in the process of trying to make contact.
Measuring the data
How the data was collected
UK level testing data is collated centrally by DHSC from multiple sources across the different nations and pillars. Further details can be found in the NHS Test and Trace statistics methodology.
Testing data for pillars 1 and 2 for England are provided by PHE, NHS and commercial partners. Contact tracing data are collected from management information from the NHS Test and Trace service. Details about the data sources used can be found in the NHS Test and Trace statistics methodology document.
Future development
We have integrated this data with those from other parts of NHS Test and Trace, particularly testing, to provide an end-to-end view of the service that follows the user journey. So far, UK level testing data, testing data for pillars 1 and 2 in England, testing turnaround times and NHS COVID-19 app statistics have been added. Further breakdowns for contact tracing continue to be incorporated, including complex and non-complex breakdowns, geographical breakdowns and household information.
To support user needs and data transparency, additional releases have been published alongside the weekly Test and Trace publication including:
- care home statistics up to 8 July
- people tested for coronavirus (COVID-19) between 30 January and 27 May
- weekly UK testing statistics since the start of testing
- demographic data for coronavirus testing in England between 28 May and 26 August
NHS Test and Trace continues to provide information for local authorities and their partners so that they have the information they need to help contain any outbreaks. In time, NHS Test and Trace intends to publish detailed data from across the program to support secondary analysis, for example in academic institutions. Over the coming months, we intend to make the following available:
Expected Autumn 2020
- details of close contacts who go on to test positive
- high-level UK Test and Trace figures
- additional demographic information for people tested
- details on testing in care homes
The UK Statistical Authority has published a rapid review of the Test and Trace statistics. This includes recommendations on how the publication should develop it order to adhere fully to the Code of Practice. These recommendations continue to influence the development of the publication in the coming weeks and months.
Strengths and limitations
Given the importance of this service and the commitment of NHS Test and Trace to be open and transparent with the public it serves, this data are being released at the earliest possible opportunity. However, new IT systems and statistical outputs often take a period of time to bed in. This data should therefore be treated with caution as the system and understanding of the data develops.
More information on data limitations and how the figures in this publication can and can’t be used is outlined in the NHS Test and Trace methodology.
Quality
These statistics have been put together by NHS Test and Trace and DHSC with advice from the Office for National Statistics. As part of the quality assurance process, DHSC ensures that all published figures are replicable and any issues impacting on the quality of the data are clearly stated within the publication. Furthermore, the figures are often triangulated with other published sources to verify trends in the data.
Revisions to figures previous published
Figures for people tested and people testing positive for coronavirus (COVID-19) in previous releases have been revised. These revisions are because:
- there are sometimes delays in laboratories submitting data to PHE
- quality checks are conducted on the data to refine figures over time
Figures for pillar 2 testing turnaround times in previous releases have been revised. These revisions are because:
- there has been a change in methodology for how the location of home tests and satellite tests is assigned. The new methodology uses the individuals home address instead of the address of the laboratory. This has resulted in an increase in the number of tests in England as a large number of tests from England were being processed in laboratories outside of England
- the figures presented are based on a data-cut several days after the end of the reporting period. Some tests may continue to be being processed after this period and therefore data may need to be revised over time
Figures for contact tracing in previous releases have been revised. These revisions are because:
- the figures presented are based on a data cut several days after the end of the reporting period, to give time for cases reported towards the end of the 7-day period to have an outcome. Some cases may continue to be in progress after this period, and therefore data may need to be revised over time
- typically, one week after initial publication the number of cases reached and consequently the number of contacts identified is expected to increase. Similarly, the number of cases and contacts reached within 72 hours is likely to increase
Cumulative figures for coronavirus (COVID-19) testing in the UK have been revised. These revisions are because:
- for tests processed and tests sent out, weekly totals reflect the sum of actual daily counts reported for the previous week. Each week there may be corrections to previously reported figures, for example, where labs (or studies under pillar 4) returned the results late or duplicates were identified and removed. These corrections are reflected in the cumulative figures. This means that previously published weekly counts will not necessarily sum to the latest cumulative figure. It also means that the latest cumulative count may not match the previous week’s cumulative count plus this week’s weekly count
More information on quality and how this publication adheres to the Code of Practice for statistics is available in the statement of compliance.

Deduplicated for the reporting week. For information on how the number of people are tested, and tested positive, in a reporting week is measured see the NHS Test and Trace statistics methodology. ↩ ↩2
-
Based on the median turnaround time for in-person tests. ↩
-
Swab testing is testing to see if someone has COVID-19, see the terminology section for more information. ↩
-
Deduplicated for the reporting week, methodology was revised from 15 October. See NHS Test and Trace statistics methodology for more information. ↩
-
Deduplicated since testing began and the end of the most recent reporting week. People tested multiple times in this time period will only be counted once. See NHS Test and Trace statistics methodology for more information. ↩ ↩2

Includes a small number of people who had a test under pillar 4 (serology and swab testing for national surveillance). ↩
-
Note that these figures may not always align with other published figures for people tested and people tested positive for COVID-19 under pillars 1 and 2 due to the timing of data cuts. ↩
-
For all measures of time taken to receive a COVID-19 test result, there are a number of tests that were not completed. This covers any test where the results were not communicated, which may be because communication details (for example, phone number or email address) were not provided or were incorrect, or because the test was cancelled or abandoned, or no result was available. It also includes some tests which are still being processed. ↩
-
Previously local test sites were included together with regional test sites but from 17 September have been split out as a separate group. ↩ ↩2
-
All positive test results under pillar 1 and pillar 2 should be transferred. In addition, all positive swab test results as part of prevalence studies (pillar 4) are also transferred to Test and Trace. People tested under pillar 3 (serology testing to show if people have antibodies from having had COVID-19) do not have their cases transferred to NHS Test and Trace. ↩
-
If NHS Test and Trace is not able to reach an individual testing positive or if no communication details are available, then it is not always possible to know if the case is complex or non-complex. Therefore, these breakdowns are not available. ↩
-
The regional data uses a different data cut to the main publication therefore cumulative totals will not exactly match. The data is available for the cumulative figures since Test and Trace launched up to the most recent week of reporting. Due to revisions that occur each week one week’s cumulative figures cannot be subtracted from a previous week’s to obtain weekly data by UTLA. ↩ ↩2
-
Timing data does not include non-complex contacts which were subsequently escalated to complex. ↩
-
See more detail in scaling up our testing programmes. ↩
-
Please note the number of test results processed sent out is not the same as the number of people tested, because people may be tested more than once. ↩
