A positive antibody test means that you have antibodies to COVID-19 in your blood. Antibody tests check to see if you’ve developed antibodies against COVID-19, which occurs after being exposed to the virus. Having antibodies usually gives immunity from further infection. However, there is not enough evidence at this time to suggest that people who have antibodies are protected against future COVID-19 infections. Visit the CDC website for further information.
A negative PCR test means that you are not currently infected with COVID-19.
