In this article, we’ll discuss what it means when your test shows “invalid”. We’ll as well delve into some causes of invalid pregnancy test and a guide into what to do next when faced with it.
Note: An invalid pregnancy test result means it is impossible to determine if you are pregnant or not, usually due to issues with the test itself.
There are some possible causes for an invalid test result, which we’re going to discuss into detail in this article.
What is a pregnancy test?
A pregnancy test is a tool that determines whether you’re pregnant or not. When you make a pregnancy test, the kit or method you use starts detecting the presence of a pregnancy hormone in your urine or blood.
When it’s able to detect these hormones, then Yes! You’re pregnant. Conversely, when it doesn’t detect any, then you certainly aren’t pregnant.
But what does it really mean when it shows invalid? That’s what this article is basically going to talk about, let’s get reading.
What does invalid mean on a pregnancy test?
So your results showed “invalid”, and that has kept you wondering what it really means.
When your pregnancy test result shows “invalid”, it simply means the test is uncertain, in other words, the test kit wasn’t able to decide or determine whether you are pregnant or not.
What causes invalid pregnancy test?
There are a number of reasons for an invalid result. Some reasons may include
1. Failure to Follow Instructions: Not using the test kit properly or not following the instructions correctly can cause an invalid result. This includes not saturating the absorbent tip with enough urine.
2. Handling or Storage Problems: If the pregnancy test stick is stored improperly, like being exposed to excessive heat, or if it’s taken out of the package too long before it is used, it can produce an invalid result.
3. Faulty or Expired Test: Using a damaged or expired test can also lead to an invalid result. Sometimes, a defect in the manufacturing of the test can lead to an invalid result.
4. Testing Too Early: Testing before the missed period when the hCG hormone has not risen enough to be detected can cause a test to be invalid.
5. Inappropriate Handling: If the test stick is taken out of the package too long before it is used, it can produce an invalid result.
6. Interference from Medications: Certain medications can interfere with the test’s ability to measure hCG levels, causing an invalid result.
7. Chemical or Ectopic Pregnancy: A chemical or ectopic pregnancy can cause hCG levels to fluctuate, leading to contradictory or invalid test results.
In the event of receiving an invalid test result, the best course of action should be to take another test, making sure to follow all the instructions and guidelines accurately
Always refer to a healthcare provider for proper understanding, and retake the test if the result is invalid.
Can I use an invalid pregnancy test again?
While you may be considering of re-using a test kit that initially showed invalid, it is generally not advisable.
Pregnancy tests are designed to be single-use items. Once opened, the strip loses its sensitivity and hence reusing it will not yield valid results. Besides, reusing a pregnancy test could potentially lead to infections.
