When to test for COVID-19?

  • If you have symptoms, test immediately.

  • If you were exposed to COVID-19 and do not have symptoms, wait at least 5 full days after your exposure before testing. If you test too early, you may be more likely to get an inaccurate result.

  • If you are in certain high-risk settings, you may need to test as part of a screening testing program.

  • Consider testing before contact with someone at high risk for severe COVID-19, especially if you are in an area with a medium or high COVID-19 Community Level.
