Can a Pregnancy Test Be Wrong?

Are you upset by the results of your pregnancy test? There are many women out there just like you. Some are hoping to be pregnant, while others are hoping not to be. Is there ever a time when a pregnancy test can be wrong?

In short, yes – there are times when at-home pregnancy tests can produce false-positive, or false-negative results.

Medication interference

Certain medications and fertility drugs that contain HCG may interfere with test results. Most medications, including birth control, will not affect the accuracy of a pregnancy test.

Early tests

If a test is taken early after a missed period, it may produce false-negative results. At this stage, it is difficult for the test to detect HCG.

Ideally, a pregnancy test should be taken one week after a missed period. If it’s not possible to wait that long, a blood test should be taken by a health care provider.

Diluted urine

If you take a pregnancy test after drinking a lot of fluid, it can cause a false-negative result. The excess fluid makes it difficult to detect HCG, which will interfere with the accuracy of the test.

Pregnancy tests are best taken early in the morning when urine is the most concentrated.

Checking the test too early

Some women are eager to see the results, but it’s important to give the test time to work. The package instructions will tell you how long the test takes. If necessary, set a timer, so you can be sure that you have given the test enough time.

False-positive tests

While it is possible to get a positive result from a pregnancy test when you’re not pregnant, these instances are rare.

In some cases, women lose a pregnancy just after the fertilized egg attaches to their uterine lining and wind up with a false-positive pregnancy test.

False-positive results can also occur if the test is taken soon after taking a fertility drug with HCG.

Menopause and an ectopic pregnancy can also interfere with the accuracy of a pregnancy test.

What to do next

If your pregnancy test is positive, or you have taken several tests with mixed results, schedule an appointment with your health care provider as soon as possible. A blood test or a pelvic exam may be performed to determine whether or not you are pregnant.

If your test result is negative, but your period does not begin, take the test again in a few days or a week. If the test was taken just before or right after a missed period, it may be a false-negative result.

If your tests continue to be negative and you still have not started your period, see your health care provider right away. There are many things that can cause a missed period, including illness, excessive exercise, stress, weight loss and hormonal imbalances. If you are not pregnant, your health care provider can help you determine the cause of your missed period. On the other hand, your health care provider can confirm that you are pregnant through a blood test or pelvic exam.
