What to Know About Antibody Testing
A COVID-19 antibody test is a blood test that can tell if you previously had COVID-19 and have since recovered. The test involves having your blood drawn at a healthcare facility. It checks for the presence of a particular antibody your body makes when it’s fighting the virus. These antibodies appear in your bloodstream after you’ve been infected. This test is not the same as a nasal swab test and does not check for the presence of the virus that causes COVID-19. You should not get this test if you’re currently experiencing symptoms of COVID-19.
