Expired COVID Tests May Still Be Accurate if FDA Extends Dates
-
Expired at-home COVID-19 tests may still be accurate if the FDA has extended the expiration date. Check the FDA website to see if your test's expiration date has been extended.
-
Test kits look for antigens and have expiration dates, but can still work beyond that date if the test materials haven't degraded.
-
Retest with a new kit if you have symptoms or exposure, even if an expired test was negative. Antigen tests can give false negatives.
-
Before using an expired test, check that the control line still appears. If not, the test is no longer usable.
-
Free COVID-19 testing is available from some local health departments and pharmacies if you need a new test kit.
