When antibody testing is useful
Antibody testing, also known as serology, can be done throughout all stages of viral infection. Antibodies start developing within 3 weeks after initial infection and last after all symptoms have gone away. They also show up when no symptoms are present in asymptomatic cases.
Is another test needed?
A second antibody test as well as a PCR or antigen test is needed to confirm positive results.
