COVID antibody test
Infection exposure screening
A COVID antibody test is a blood test that detects antibodies produced by the immune system in response to a SARS-CoV-2 infection or vaccination.
Unlike tests that detect active infection, antibody tests reveal whether someone has previously been infected or has developed an immune response: Her COVID antibody test came back positive, suggesting she'd had the virus at some point.
