Do COVID-19 tests still work after they expire? Here's how to tell.

With COVID-19 cases on the rise again in the U.S., Americans are reviving a familiar precautionary measure: Screening for the virus using rapid at-home tests.
Many people still have kits the government formerly provided to all households for free, especially as some schools and businesses again require tests. Yet different COVID-19 tests bear expiration dates on their packaging that have long since passed, raising questions about whether they're still effective.
Once in short supply, test kits are now easier to come by but are costly, costing roughly $25 for a pack of two tests. The White House sent rapid at-home COVID-19 test kits free of charge to Americans who requested them as recently as last December as part of its "winter preparedness plan."
