An antibody test is a blood test to check if you’ve either:
- had coronavirus (COVID-19) before
- made antibodies to the virus after having the COVID-19 vaccine
Some people who’ve had the virus or the vaccine do not have antibodies. This means the test does not work for everyone.
An antibody test is different to a test to check if you have COVID-19 now. Find out about tests to check if you have COVID-19 now
The antibody testing service to check if you’ve had COVID-19 closed in March 2022.
You can no longer register to get an antibody test kit.
If you opted to take part in antibody testing after a positive PCR test result on GOV.UK and returned your test kit before the service closed, you should still receive your test result. You will not receive your second test kit.
If you’re taking part in a research study, follow the guidance that the research study has given to you. Contact your research study co-ordinator if you need help.
If you want to get an antibody test, you can pay to have a test at a private clinic.
