COVID-19 tests can detect either SARS-CoV-2 or biomarkers of SARS-CoV-2, the
virus that causes COVID-19, or antibodies that your body makes after getting
COVID-19 or after getting vaccinated.
Antigen Test
Antigen tests are commonly used in the diagnosis of other respiratory pathogens, including influenza viruses and respiratory syncytial virus (RSV). The U.S. Food and Drug Administration (FDA) has granted emergency use authorization (EUA) for antigen tests that can identify SARS-CoV-2.
