How To Check Your Test

  • 1

    Find the expiration date on the box.

    Example expiration date. (Your test may look different.)

    Check the box for the "Expiration" or "Use By" date. Some boxes use a drawing of an hourglass for the expiration date.

    If the date is in the future, the test hasn't expired and is fine to use.

    If the date has already passed, continue these steps to see if the expiration date has been extended by the FDA.

    Find the lot number on the box.

    The lot number is printed near the expiration date, and may be a combination of letters and numbers. You'll need it for the next step.

    Find your test and look up the expiration date and lot number.

    Look up your lot number by clicking your brand of test below. You'll be taken directly to the FDA's information on that brand.

    Some tips:

    1. It's often easier to look for the printed expiration date first, then the lot number. (The documents linked here can be quite long.)
    2. However, finding the lot number is most important. If your test's lot number appears, trust the extended expiration date, even if the printed expiration date doesn't match yours.
    3. If your test's lot number doesn't appear, the test's expiration date may not have been extended. Throw it away.
