I received a test kit that is expired. Should I be concerned?

You may be concerned that your test kits have passed their expiration dates.

That expiration date was based on the Food and Drug Administration (FDA) needing more evidence of shelf stability. As new tests on the market, manufacturers could not provide this evidence when the kits were first released.

Now, most of the test kit companies have provided follow-up information to the FDA, which extended their expiration dates. You can look up your test kits by manufacturer at this webpage to see their new expiration date.
