1. What Is A False Positive Pregnancy Test? 

A false positive pregnancy test is when a woman receives a positive result on a home pregnancy test, but she is actually not pregnant. For the most part, today’s home pregnancy tests are very reliable and work very well.


However, when the instructions are not followed properly, a false positive test can result. There are other reasons that can cause a false positive reading on a home pregnancy test as well. Today we will explore a few of the most common reasons for a false positive home pregnancy test.

2. Chemical Pregnancy

Chemical pregnancy, or early miscarriage, is one of the most common reasons for a false positive result on a home pregnancy test. A chemical pregnancy results when a fertilized egg does not implant for some reason. The pregnancy is lost shortly after it began.


If a woman tests at home before the early miscarriage occurred, she can receive a positive result when she is not actually pregnant. This is one downside to our technological advancements and ultra-sensitive pregnancy tests that have come about in recent years.

3. Improper Testing/User Error

Another common cause of false positive pregnancy tests is improper testing procedures, or user error. It is very important to follow the instructions carefully when you are using a home pregnancy test, or issues can occur.


For example, some home pregnancy tests will produce a faint positive line if they are read too long after the testing time. Some women will go back to check their results after taking a home pregnancy test, only to think that they are now getting a positive result when they are actually just misreading the test. This is why it is very important to read the test results at the proper time.

4. Medications

Rarely, there are some medications that can cause a false positive result on a pregnancy test. For example, if a woman is receiving hCG therapy for a luteal phase defect or other fertility problem, that can lead to a false positive result. However, most of the time, if a woman is taking a medication that will interfere with her pregnancy test results, she will already be aware of that and will already have discussed it with her doctor beforehand.


5. Defective Tests

Very rarely, a woman might get a false positive result on a home pregnancy test due to a problem or issue with the test itself. Women should always make sure to check the expiration date on a home pregnancy test before using.


It is also important to remember that even with the best quality tests from the best brands, occasionally a defective test can make it’s way in and a false positive test can occur. Women should be very careful to follow all test instructions. If a woman takes a pregnancy test and thinks that a false positive result has occurred, she should wait a few days and test again.
