Some pregnancy test brands claim their tests are 99% accurate when run correctly. However, false results sometimes happen for several reasons, especially false-negative tests due to timing or other factors.
However, what about a false-positive test? They are rare but still possible.

How Do Pregnancy Tests Work?
Pregnancy tests (both urine and blood) detect the presence of a hormone called human chorionic gonadotropin (hCG). When the fertilized egg attaches to the uterine lining and the placenta begins forming, hCG production begins.
As the pregnancy progresses, the amount of hCG increases. For the most accurate result, it is recommended until after you have missed a period to take a test, as it takes time for hCG to rise to detectable levels.
How Do False-Positive Tests Occur?
False-positive tests are rare. However, here are some reasons why a false-positive result may occur.
1. A Pregnancy Occurred, But There Was an Early Miscarriage.
Most miscarriages happen in the first twelve weeks of pregnancy. Many occur very early, even before testing occurs.
HCG can remain in the woman’s body after the pregnancy loss, resulting in a false positive. Technically, the pregnancy test would have been correct that the woman was pregnant, but it may appear to be false as the pregnancy will not continue.
2. The Woman Had Fertility Treatments
Some fertility treatments contain hCG, which could result in a false positive test. If you’ve received an hCG injection, it’s best to wait two weeks until you take a pregnancy test.
3. The Woman Has Recently Given Birth
HCG can remain in the system for four to six weeks after giving birth. Once a woman’s body clears the hCG, she should no longer receive a positive pregnancy test.
4. User Error
User error can occur if the woman has waited too long for results or used too many drops of urine.
Pregnancy tests can differ. Even if you have taken tests before and are confident about how they work, always read the test’s specific instructions and follow them for more trustworthy results.
5. The Woman Has Recently Given Birth
HCG can remain in the body for four to six weeks after giving birth. Once a woman’s body clears the hCG, she should no longer receive a positive pregnancy test.
Other reasons for false-positive test results can also include issues with the ovaries and menopause.
