Will my Self-Test Work if I'm Vaccinated? Can it Detect Variants?

How do I know my COVID-19 self-test will work?

If I am vaccinated or unvaccinated, will the self-test still work?


Yes, you can use a self-test regardless of whether or not you've been vaccinated.


How long do I need to be sick before I use the self-test kit?

You can use self-tests even if you're not sick. If you have COVID-19 symptoms, you should get tested as soon as possible.


Will this test detect variants?

Self-tests can't tell you exactly which variant of the virus has been detected. FDA has been monitoring the potential impact of variants on antigen tests (self-tests are also known as rapid antigen tests). Early data suggests that antigen tests do detect the omicron variant but may have reduced sensitivity. Click here for more information.
