When are rapid antigen tests for COVID-19 most accurate? Rapid antigen tests are most accurate when they are used in people who have signs or symptoms of COVID-19, especially during the first week of illness. People who test negative may still be infected.
Do I need to stay home if I test positive for COVID-19? If you test positive for COVID-19, stay home for at least 5 days and isolate from others in your home. You are likely most infectious during these first 5 days. Wear a high-quality mask if you must be around others at home and in public. Do not go places where you are unable to wear a mask.
How long after exposure should you get tested for COVID-19? Consider getting tested 3-5 days after exposure, even if youre vaccinated and dont have symptoms.
