How accurate is the test?

The antibody test will be conducted in a research lab, and not an NHS clinical-grade lab and is not 100% accurate or reliable at an individual level. The results show whether or not you have COVID-19 antibodies but cannot give a completely reliable individual diagnosis of whether you have had the virus. It is not known whether having COVID-19 antibodies will prevent re-infection, so regardless of your test result you should continue to follow government guidelines on self-isolation and social distancing. In addition, we encourage all study members to have the COVID-19 vaccine when offered, regardless of your antibody test result.
