Pregnancy Tests Expire

When Do Pregnancy Tests Expire

All pregnancy tests have an expiration date stamped on the packaging — but that date is two to three years from when the test was manufactured. For example, if you buy a digital test in January 2021, it will expire on December 2022, or about three years after you purchased it.

Most pregnancy tests have an expiration date two to three years from the day they were made. But that doesn’t mean a test will be good for that long after you buy it..Just like food, a test can go bad if it is not stored properly.

Most pregnancy tests are good for two to three years after purchase. But even if the expiration date has passed, it’s important to understand how long a test can last — because expired tests may not give you an accurate result.

If you’re wondering how long do pregnancy test last, most pregnancy tests have a shelf life of two or three years from the date of manufacture, according to Consumer Reports. The brand name usually isn’t a good indicator, though — one test that Consumer Reports tested lasted for only two months past its expiration date, while another tested well after its date for eight months.

Most pregnancy tests last for two to three years. But that doesn’t necessarily mean a test will be good for that long after you buy it. All tests have an expiration date stamped on the packaging — but that date is two to three years from when the test was manufactured. So if a test was sitting on the store shelf for a while before you bought it, the expiration date might be less than two to three years away

The lesson? Always check the expiration date before buying. And if you have a pack on hand for a while, look at the expiration date again before you actually take one of the tests. If it’s expired, throw it out.

One other thing to keep in mind: You can only count on a test’s expiration date if the test has been stored correctly. Excessive heat or humidity can cause pregnancy tests to degrade faster, and it’s possible for them to go bad before the date printed on the label.

Keeping your test in a dry, room-temperature space (like the bathroom) is just fine. And if you’re concerned, the test will list appropriate storage conditions right on the packaging.

How Long Do Unused Pregnancy Tests Last

Pregnancy tests are good for 1-3 years after manufacture. The one you keep in your medicine cabinet might last longer, but it will still expire at some point.

If unopened, most pregnancy tests are good for 2 to 3 years. This means that you should be able to use them for about the same length of time after you begin trying to conceive. If a test has left a urine mark, there’s probably no point in using it if you test later than 5 days after conception.

Pregnancy tests have a shelf life of about 3 years past the date of purchase. There are a couple reasons for this: 1. The chemicals in the test can break down overtime, and 2. The dye that is used for the positive test line in these tests can also spoil over time. (The answer to both questions is “oxidation”).

You can use these tests up to 3 years after the original purchase date. The expiration dates of pregnancy tests varies by brand and individual test, but most can be used up to 3 years after the purchase date.

Pregnancy Test Expired A Month Ago

An expired pregnancy test could give you an accurate result, but experts agree that you shouldn’t take a chance. In general, pregnancy tests that are past their expiration date are more likely to give you a false negative or a false positive reading. So it’s not a good idea to use them

You may still be able to use an expired pregnancy test. But experts agree that you shouldn’t take a chance, since more false-negative and false-positive test results could occur if the tests are past their expiration date.

It’s a good idea to follow the expiration dates of over-the-counter pregnancy test kits. Expired tests are more likely to give you an inaccurate results and nothing will be more disappointing than setting up your missed period, only to find out that you’re not expecting.

Do pregnancy tests expire?

Yes. Like many of the other items in your medicine cabinet, pregnancy tests don’t last forever and do expire.

To understand why, it helps to know a little bit about how they work. Pregnancy tests work by measuring levels of the pregnancy hormone human chorionic gonadotropin (hCG). HCG starts showing up in a woman’s urine (and her blood) within six to 12 days after fertilization, and her levels go up every day after that, peaking between 7 and 12 weeks of pregnancy.

The test strips on pregnancy tests contain a chemical that detects the hCG in a woman’s urine to confirm that she’s pregnant. But the chemical has a shelf life, and after the test’s expiration date, it becomes less effective at detecting hCG. As a result, the pregnancy test is more likely to give you an inaccurate reading. False negatives are more likely, but it’s also possible to get a false positive.

In short, pregnancy tests do expire. And using one past the expiration date could give you an inaccurate result.

When should you take a pregnancy test?

You can take a pregnancy test anytime before the use-by date listed on the package. To increase your chances of a reliable reading, wait at least until the day of your expected period to test. And be sure to follow the instructions on the packaging.

Is it okay to buy a box of pregnancy test sticks or strips in advance while you’re trying to conceive?

Absolutely. It’s fine to keep a package around for a few weeks, a few months, or even longer — as long as you check the expiration date before you use a test. If it hasn’t passed yet, you’re in the clear.

The bottom line is that all home pregnancy tests have an expiration date, and using an expired test can increase the chance of getting an inaccurate result. The date is stamped right on the packaging, so check it before you buy the test. And if you don’t open the package to use one right away, check the date again before using it to see whether you’re pregnant or not.No matter what your test result turns out to be, you’ll need to get your pregnancy confirmed by your OB/GYN or midwife anyway. But it’s best to try for the most accurate reading possible before you make your appointment, for your own information and peace of mind as much as anything. And if you have any questions at all about taking a pregnancy test or reading the results, check in with your practitioner.
