You don’t necessarily have to throw away that at-home COVID-19 test just because the expiration date on the package has passed.

and look for the name of your test. You’ll need the lot number printed on the box. The first expiration date may be inside the box, on the some of the test parts.

If the expiration date has been extended, you should be able to find the old and new dates. If there’s no new expiration date, the date on the package is still valid, the FDA says The FDA says that COVID test makers have two ways of determining whether a product has expired, called stability testing. In real-time testing, the manufacturer stores tests for the same amount of time as a proposed expiration date. If the manufacturer goes with a 12-month expiration date, they will check the test’s ability to perform accurately after 13 months of storage, the FDA says.

The FDA says accelerated testing usually gives “sufficient assurance to label tests with a shelf-life of up to six months.”Jamie Alan, Ph.D.
