There are few things more exciting than the possibility of a pregnancy. But, for some women, that excitement can be deflated with a false positive on a pregnancy test. False positives can be confusing and even heartbreaking.

However, they are not uncommon, and there are several reasons why they can occur.

What Is a False Positive Pregnancy Test?

A false positive pregnancy test occurs when a test indicates that a woman is pregnant when she is actually not. This can happen for a variety of reasons, including user error, expired tests, and certain medical conditions or medications.

User Error

User error is one of the most common causes of false positive pregnancy tests. This can happen if the test is not used correctly, or if the results are misinterpreted.

For example, a woman may misread the test results if she checks the test too early or too late. Additionally, certain medications such as fertility drugs or hormone injections can affect the accuracy of the test; it’s important to read all instructions and consider these factors before testing.

Expired Tests

An expired pregnancy test can also result in a false positive. Over time, the chemicals and materials used in the test can break down and become ineffective. Always check the expiration date on the test before use.

Medical Conditions and Medications

There are certain medical conditions and medications that can also cause a false positive pregnancy test. For example, a woman who has recently had an ectopic pregnancy may continue to test positive for weeks after the pregnancy has ended.

Similarly, some medications that contain the hormone hCG may cause a false positive result. These include fertility medications and some treatments for ovarian cysts.

What Can Be Done to Prevent False Positives?

The best way to prevent a false positive pregnancy test is to use the test correctly and follow all instructions carefully.

Additionally, avoid using expired tests, and be aware of any medical conditions or medications that may impact the accuracy of the test. If you are unsure of whether or not a medication can impact the accuracy, speak with your doctor before testing.

What to Do If You Get a False Positive

If you receive a false positive test result, the best thing to do is to speak with your doctor. He or she can perform a blood test to confirm whether or not you are pregnant.

It’s important to take action quickly so that you can receive the appropriate medical care.

The Bottom Line

A false positive pregnancy test can be disappointing, but with proper care and attention, they can often be avoided.

Always follow all instructions closely, look for any expiry dates, and be aware of any medical conditions or medications that may impact the accuracy of the test. If you receive a false positive result, speak with your doctor as soon as possible to receive a confirmation test and appropriate care.
