The U.S. Food and Drug Administration (FDA) has extended the expiration dates for many at-home COVID-19 tests. Because these tests were quickly developed during the pandemic and authorized for emergency use by the FDA, many have short expiration periods (e.g., six months). As more time passes and test manufacturers can show that tests continue to work well beyond the initial expiration period, expiration dates are extended. If your at-home COVID-19 test has expired, check this website to see if the expiration date has been extended.
