What is a COVID-19 Antibody Test?

This test will identify if you have any antibodies to COVID-19. These tests are also called serology tests.  Antibody tests look for the body’s response to an infection instead of looking for the virus itself.  Antibodies are proteins that the body makes to fight off infections. They are one part of the immune system response to infection. Because it takes days to weeks for the body to create antibodies, these types of tests are not recommended for initial diagnosis of COVID-19.

This is not a test to diagnose COVID-19. If you have symptoms or if you were recently exposed and you need to be tested to find out if you have COVID-19, RT-PCR testing (nasal swab) is more appropriate for you.
