Rapid Antigen Covid Testing

A 15-Minute Nasal Swab Test

An antigen test looks for proteins found on or within the virus. It tells you if you have COVID-19 right now and could spread it to other people. An antigen test is like a PCR test, where a sample is collected with a nasal or nasopharyngeal swab, but you are able to get the results much quicker. Results take about 15 minutes.

Antigen tests can detect only high amounts of virus and are less sensitive than PCR tests. They work best when someone has symptoms of COVID-19. Antigen tests are most accurate during the first 5-7 days of your illness when your viral load is highest.
