The Truth About Expired Covid Tests During the Surge

As the availability of lab P.C.R. tests declines, at-home rapid tests have become more important in detecting Covid-19. However, it is crucial to check the expiration date of the test, as expired tests may not provide accurate results. The FDA has extended expiration dates for certain brands, which can be checked on their website. Extreme heat can also damage at-home tests, so it is recommended to wait at least two hours after delivery on hot days. Testing guidelines vary depending on symptoms and exposure, with immediate testing recommended for those with symptoms and recent exposure. Testing multiple times, especially if asymptomatic, is advised for accurate results. Additionally, individuals who experience Paxlovid rebound should test within two to eight days after recovery, as rebound cases can still be contagious.
