An antibody test is a blood test to check if you’ve had coronavirus (COVID-19) before. You can register for an invite to get a test kit.

The antibody test is a home test kit sent to you in the post.

It’s different from the test to check if you have coronavirus now.

Who can register for a home test kit

The rules for who can register for an antibody test depend on:

  • where you live
  • your job

If you’re in England

You can only register for a test kit if you’re 18 or over and you work in paid adult social care.

If you’re in Wales

You can only register for a test if you’re 18 or over and you work in paid domiciliary care (caring for people in their homes).

If you’re in Northern Ireland

You can register for a test as part of a study to understand the spread of coronavirus.

You must be 18 or over and one of these must apply:

  • you work in primary care (for example a GP, pharmacist, community nurse, dental nurse or optician)
  • you do any job in a care home
  • you’re a care worker in paid domiciliary care (caring for people in their homes)

Not everyone in Northern Ireland who registers will get a test.

If you’re in Scotland

You can register for a test kit if you are:

  • 18 or over
  • working in education (teaching or non-teaching staff)
  • based in an early years education, primary, secondary or an additional support for learning school setting

If you got an invitation email, you also can join Public Health Scotland’s coronavirus antibody survey. This will make sure your test result is as helpful as possible to Scotland’s response to coronavirus. Check your invitation email for the key code to join the survey.

About the antibody test kit

The test is a ‘fingerprick’ blood test which checks for coronavirus antibodies.

The test kit is posted to you. It comes with everything you need. You take the test and post your sample back. Then you’ll get your results.

This service is only for registering for an antibody test kit by post. You cannot use it to book a test at an NHS test site.

What the antibody test can tell you

An antibody test can tell you if it’s likely you’ve had coronavirus before.

An antibody test does not tell you:

  • if you’re protected from coronavirus
  • if you can or cannot spread the virus to other people

Why take the test

Taking the test helps the NHS and research scientists learn more about who’s had the virus and how it has spread.

Register for a test kit

Once you’ve registered, you’ll get an email or text message inviting you to order a test kit. This can take a few weeks.
