What happens if you use an expired pregnancy test?

Do expired pregnancy tests work? Once a pregnancy test expires, the antibodies it uses to detect hCG levels begin to break down. This means the test may not be able to detect hCG levels that a nonexpired pregnancy test could, which could lead to a false negative result. What happens if you take an expired pregnancy test Because urine tests become less sensitive over time, they will eventually lose their ability to detect pregnancy entirely. This means if you use an expired pregnancy test, you are more likely to get an inaccurate result. Apart from a laboratory setting, you cannot determine if the chemical on the pregnancy test strip is inert or still active after the expiry date. Do not bother using an expired test strip. If you’re buying multiple tests, rather take the extra time to examine several tests and purchase only those with expiration dates as far off as possible.



Can you use expire pregnancy test?

Do expired pregnancy tests work? An expired pregnancy test could give you an accurate result, but experts agree that you shouldn’t take a chance.

How long is a pregnancy test good for after expiration date?

Generally, tests are good for 1 to 3 years after manufacture. A high quality, extra sensitive test may last longer than your run-of-the-mill “internet cheapie” test (as they’re called in trying-to-conceive forums; an example can be found for purchase online here). But the point is, they all have a shelf life.

Will an expired pregnancy test give a false negative?

Your pregnancy test is expired or faulty. If your pregnancy test is expired, it might give a false negative result. This is because the antibodies in the test that react to hCG hormones slowly evaporate over time – eventually there will be too few antibodies to accurately sense hCG.
