Yes, at-home over-the-counter (OTC) COVID-19 diagnostic tests have expiration dates printed on their packaging. Generally, you should not use a test past its printed expiration date. However, the FDA has extended expiration dates for many tests after receiving additional data from manufacturers demonstrating continued accuracy.
Understanding COVID-19 Test Expiration Dates
-
Printed Expiration Date: All at-home OTC COVID-19 tests display an expiration date on the packaging. This date indicates the manufacturer's guarantee of test accuracy and reliability. Using a test past this date increases the risk of inaccurate results. [Source: FDA]
-
FDA Extensions: The Food and Drug Administration (FDA) frequently extends expiration dates for many COVID-19 tests. These extensions are based on additional data showing the tests remain reliable beyond the initially printed date. [Source: FDA, NYT]
-
Checking for Extensions: Before discarding a test past its original expiration date, check the manufacturer's website or the FDA website to see if an extension has been granted. Several state health departments also provide updates on expiration date extensions. [Source: NC DHHS, NJ COVID-19 Website]

Risk of Inaccurate Results: Using an expired test, unless an extension has been issued, significantly increases the chance of receiving false-positive or false-negative results. This can lead to incorrect health decisions and potentially delayed or inadequate treatment. [Source: Mayo Clinic, UNMC, Cleveland Clinic]
How to Determine if Your COVID-19 Test is Still Valid:
- Locate the Expiration Date: Find the expiration date printed on the test's packaging.
- Check for Extensions: Visit the FDA website, the manufacturer's website, or your state's health department website to see if an extension applies to your specific test.
- Use Only if Valid: Only use the test if the expiration date is in the future or has been officially extended.
