No. There is almost nothing that can cause a false positive pregnancy test, and all of the causes require an urgent visit to a health care provider.


Malfunctioning thyroids can't; they don't produce the correct hormones to trigger a pregnancy test. But to swear nothing can cause a false positive is irresponsible and false in it's own right. I've been the victim of a false positive test. Always be sure to test in the morning when urine is more concentrated. It's also best to avoid drinking a ton of water before testing, or after to try and test again. This can mess with the test and give false results.

1. False positive pregnancy test due to improper testing...

Improper testing can lead to false positive results. Always follow the directions! Instructions will specify when test results are no longer valid. You should time and record the time you perform the test, and read results at the instructed time. Guessing can lead to false results. "Double checking" your results often leads to false positives. Fishing your test out of the garbage after too much time has passed can change the initial results.

2. Evaporation line on a pregnancy test...

With some tests you can see where the testing line is. When urine runs across the test strip it can briefly change the color. Some tests allow you to see what can best be described as a watermark; kind of like what you see on US paper currency. If there is no color or you have to really mess with it in the light to see a line; it could be an evaporation line. Try retesting in a few days or using a digital test is recommended.

3. False positive pregnancy tests can be caused by certain medications...

Sometimes urine can be contaminated with blood or large amounts of protein, which can lead to false positive results.

4. Certain medical conditions can lead to false positive test results...

If you receive a positive result from a home pregnancy test it is important to see your doctor. It's is not common, rare medical conditions can cause false positive results on home pregnancy tests. Certain cancers, can cause higher levels of hCG levels.

5. Defective pregnancy tests...

Expired or faulty tests can also lead to false positive results. Remember, an occasional defective test may come out of a batch.

If you're unsure about the results of your home pregnancy test, ALWAYS consult your doctor.
