Can Certain Medical Conditions Affect Pregnancy Test Results?

Yes, certain medical conditions can affect pregnancy test results. This article will highlight those medical conditions.

However, If you recently took a pregnancy test and are worried you can’t trust the results, it’s critical to follow up with an ultrasound. This scan can confirm pregnancy and thus rule out other health conditions.

Understanding How Pregnancy Testing Works

Pregnancy tests detect the presence of human chorionic gonadotropin (hCG), a hormone produced after a fertilized egg implants in the uterus. This hormone is typically absent in non-pregnant individuals, making it a clear marker of pregnancy.

Home pregnancy tests measure hCG levels in urine, while blood tests at a healthcare provider’s office offer more precise results because they can detect lower levels.

Medical Conditions That Can Cause False Positives

Certain medical conditions can lead to elevated hCG levels even if you’re not pregnant, resulting in a false positive. These conditions include:

Molar pregnancy: A rare complication where abnormal tissue grows in the uterus instead of a normal embryo. It can cause significantly elevated hCG levels.
Ectopic pregnancy: This occurs when a fertilized egg implants outside the uterus, often in a fallopian tube. While it does produce hCG, the pregnancy is not viable and requires immediate medical attention.
Certain cancers: Some cancers, particularly of the reproductive organs or the liver, can produce hCG and mimic pregnancy symptoms.
Pituitary hCG production: In rare cases, the pituitary gland can produce hCG, especially in older women or those undergoing hormonal changes.
Recent pregnancy loss or abortion: These levels may remain detectable in the body for weeks after a miscarriage or abortion, leading to a false positive.

Why an Ultrasound Is Crucial

If you receive a positive pregnancy test but suspect it may not be accurate, an ultrasound is essential. An ultrasound confirms the presence of a pregnancy and ensures it is developing in the correct location. It can also help identify conditions like a molar or ectopic pregnancy, enabling timely, life-saving intervention.
