COVID-19 Antibody Testing

WHAT IS AN ANTIBODY? Remember, it can take days to weeks for the body to develop antibodies.

TEST RESULTS: Get your test results in 15 minutes.

A positive antibody test means that the person was infected with COVID-19 in the past or recently, and that their immune system developed antibodies to try to fight it off. You may test positive for antibodies even if you have never had symptoms of COVID-19. This can happen if you had an infection without symptoms, which is called an asymptomatic infection.

A negative test means that there is no evidence of a prior exposure or that your body has not had time to develop an antibody to the virus.

We do not know yet if people who recover from COVID-19 can get infected again, or how long antibodies to the virus will protect someone. Scientists are working to understand this.
