"Free COVID Tests Delivered to Your Home: Check Expiration Dates and Order Today"

The expiration date on your box of COVID-19 tests indicates the final day the test is expected to perform effectively. While the FDA authorizes at-home test kits with a shelf life of about four to six months, manufacturers can request an extension if they find additional data showing the tests are still accurate past the expiration date. It is not recommended to use expired tests as the components may degrade, leading to inaccurate results. To check if the shelf life of your COVID-19 tests has been extended, you can refer to the FDA's At-Home OTC COVID-19 Diagnostic Tests webpage, which lists the expiration dates and extensions for various brands.
