Standards for microbiology investigations (UK SMI)

UK Standards for Microbiology Investigations (UK SMIs) are a comprehensive referenced collection of recommended algorithms and procedures for clinical microbiology.

Please note that some review dates may be affected due to the COVID-19 outbreak and there will be delays in the review of some UK SMIs. This will be limited where possible and we would be grateful for your patience as the team navigates its way back to business as usual. Contact standards@phe.gov.uk for any queries.

Bacteriology

These are bacteriology standards for the laboratory covering receipt of the sample in the laboratory to the issue of a report.

Virology

Virology and serology diagnostic algorithms and standards for the laboratory testing of viruses.

Identification

These documents cover techniques used for bacterial identification.

These standards describe essential laboratory practices to ensure quality like assay validation, quality assurance and understanding uncertainty of measurement.

National user manual and Syndromic algorithm

The national user manual template contains standard headings and suggestions to guide laboratories in completing a national user manual. Two worked examples of use have been developed and work on this has now been completed.

The syndromic algorithm documents provide the overarching framework for all other UK SMIs.

These standards help clinicians and diagnostic laboratory staff choose the correct approach for investigating a sample from a clinical setting.

Development of syndromic algorithms has now resumed. Documents that have exceeded their review date will remain on the website until they are superseded or withdrawn.

Test procedures

These standards outline the test procedures for identifying the organisms.
