For many women, a positive pregnancy test is a long-awaited moment of joy and excitement.

But what happens when that positive result appears after the recommended testing time frame has passed?

The answer is not always clear, leaving some confused and unsure of what to do next. 

In this article, we explore the possible reasons for a pregnancy test to turn positive after an hour, the accuracy of these results, and guide what steps to take if you find yourself in this situation!

Why does a pregnancy test turn positive after an hour?

Pregnancy tests rely on detecting a hormone known as human chorionic gonadotropin (hCG) to indicate pregnancy.

hCG is produced by the placenta after the fertilized egg implants into the uterine lining.

During the early stages of pregnancy, hCG levels increase rapidly, making it a reliable indicator of pregnancy.

Pregnancy tests can produce false negative or false positive results despite their accuracy.

A false negative may occur if the test is taken too early in the pregnancy before the hCG levels have risen to a detectable level.

On the other hand, a false positive may result from the test detecting other sources of hCG, such as specific medications or medical conditions.

In certain cases, a pregnancy test may show a positive result after the recommended testing time frame, typically around 10 minutes after the test.

This can be influenced by several factors, such as: 

  • The test’s sensitivity
  • The individual’s hCG levels 
  • The test’s timing in relation to the menstrual cycle. 

How accurate are pregnancy tests after an hour?

Pregnancy tests are designed to provide accurate results within a specific time frame, usually around 10 minutes. 

However, it’s important to understand that the accuracy of a pregnancy test may decrease after this window has passed.

A positive result after an hour may not be as reliable as one that appears within the recommended time frame.

While pregnancy tests are generally considered over 99% accurate when taken correctly, the accuracy can drop significantly as time passes. 

According to a study by WomensHealth.gov, the rate of false-positive results jumps from 9% at 10 minutes to nearly 47% after one hour.

This decrease in accuracy can be attributed to a phenomenon known as an evaporation line.

An evaporation line can appear on the test strip as the urine dries, leading to a faint positive result even if no hCG is present. 

This line can become more pronounced, leading to confusion and potentially false positive results.

What should you do if your pregnancy test turns positive after an hour?

Step 1: Don’t panic

Feeling overwhelmed or anxious is natural if your pregnancy test has turned positive after an hour. However, it’s essential to stay calm and remember that you can take steps to ensure an accurate result.

Step 2: Take another pregnancy test

Taking another pregnancy test is crucial to confirm the result and rule out any potential errors or false positives. 

Here’s what you should do:

  • Use a different brand or type of test, as some tests may be more sensitive than others.
  • Follow the instructions carefully, and make a note of the result within the recommended time frame, usually around 10 minutes.

Step 3: Seek professional medical advice

If you continue to receive positive results or have doubts about the accuracy of your tests, it’s essential to speak with a healthcare professional. 

Here’s why:

  • They can provide guidance, perform additional testing, and answer any questions you may have about your pregnancy.
  • Remember, it’s always better to seek professional advice if you have any doubts or concerns.

Receiving a positive pregnancy test result can be overwhelming. Still, by taking these steps and consulting with a healthcare professional, you can receive the support and care needed to navigate this exciting (and often confusing) time.
