F9: An antibody test is a blood test to check if you’ve had coronavirus (COVID-

│19) before or been vaccinated. The test detects your body’s response to the virus or

│vaccination but cannot tell you if you had COVID-19 infection at the time of the test. In

│the past, you may have been invited to a ‘serology study’ aiming to collect information

│on exposure to COVID-19. This study involved study members providing a blood

│sample which was then tested for COVID-19 antibodies. Please do not answer this

│question based on the results of a serology study or any other antibody test you may

│have done.
