Can a COVID-19 antibody test tell me when I can visit someone who is at risk for severe symptoms of the virus?

There is no test that can tell you when you can visit someone who is at risk for more severe symptoms of COVID-19. Check with your primary healthcare provider or local health department to help determine when the time is right to make such visits. Be sure to continue to follow federal, state, and local government guidance regarding social distancing and COVID-19 safety precautions.
