What will a COVID-19 antibody test tell me?
This test may help identify if you were exposed to the virus and, if so, whether or not your body has IgG antibodies against COVID-19. Although having antibodies usually gives immunity from further infection, there is not enough evidence at this time to suggest that people who have IgG antibodies are protected against future COVID-19 infection. Results from this test also will not provide any information on whether you can spread the virus to others.
If you have questions about returning to work, contact your employer for guidance. Be sure to continue to follow federal, state, and local government guidance regarding social distancing and isolation.
