Yes, COVID tests can expire, but many have extended expiration dates beyond what's printed on the box.
Understanding COVID Test Expiration
While it's true that COVID tests have an expiration date printed on their packaging, it's important to understand that this date might not be the absolute last day the test is effective. Many manufacturers have conducted further studies and have received approval to extend the shelf life of their tests. This means that a test you thought was expired might actually still be usable.
Key Points About Expiration:
- Printed Date: The expiration date you see on the box is the original expiry date assigned during the initial approval of the test.
- Extended Dates: Many COVID-19 tests have had their expiration dates extended by regulatory bodies based on stability data, as stated in the provided reference, "Many COVID-19 tests have extended expiration dates".
- How to Check: To find out if your specific test's expiration date has been extended, you can:
- Visit the manufacturer's website.
- Check the FDA website for updated lists.
- Contact the manufacturer directly.
Why Expiration Dates Matter:
Expiration dates are placed on medical products, including COVID tests, to ensure the accuracy and reliability of the results. Over time, test components may degrade, which could lead to false positives or false negatives.
What to do with Expired Tests:
- Check for Extensions: Before throwing away any test, research if the expiration date has been extended.
- Discard if Truly Expired: If your test is confirmed to be expired, or if you cannot confirm an extension, discard it according to local guidelines.
