Do at-home COVID tests expire?

by Julio Santos January 06, 2022

More and more folks are purchasing at-home COVID-19 test kits. The fact that they are increasingly hard to find and restock is evidence that they’re a valuable tool to have in your home moving forward. But, since they come in packages of 20, you may be wondering whether or not COVID test kits have an expiration date. Here’s what you need to know about storing your tests and whether or not at-home test kits expire.

Your test kit will come with an expiration date

Check your tests and find the expiration date — it’s that easy. Research is still being conducted on the viability and accuracy of tests, but you can store most for several months or as long as a year. Plus, different brands may vary in shelf life, so it’s always important to check the date on your tests and toss them once they expire. The FDA checks the viability and accuracy of expiration rates for the tests. 

Expired tests may be inaccurate


Of course, there is a chance that an expired test could provide correct results. After all, there’s a 50/50 chance that it will determine if you have COVID-19. However, accuracy decreases after a test expires. It could also provide a false positive or false negative, negating the reason why you’re taking the test to begin with. Therefore, it’s essential to have correct results so you know how to proceed after finding out whether or not you have COVID.

Store your test kits properly

Beyond the expiration date, how you store your tests will impact the efficacy. Read the information on the test kit to see how you should keep your tests. Extreme temperatures and humidity can affect the accuracy of your results, so read the instructions thoroughly to ensure safekeeping and proper storage.
