A false positive pregnancy test can occur for a number of reasons, including:
-
User error: Taking the test too early or not following the instructions properly can lead to a false positive result.
-
Chemical pregnancy: This occurs when a fertilized egg implants in the uterus but fails to develop properly. It can result in a positive pregnancy test followed by a period.
-
Ectopic pregnancy: This is a pregnancy that occurs outside the uterus, usually in the fallopian tube. It can cause a positive pregnancy test but is a medical emergency that requires immediate treatment.
-
Recent miscarriage or abortion: Hormone levels can remain elevated for a short time after a miscarriage or abortion, leading to a false positive result.
-
Evaporation line: If a pregnancy test is read after the recommended time, it can result in an evaporation line that looks like a positive result.
-
Fertility medications: Certain fertility medications, such as Novarel, Pregnyl, Ovidrel, and Profasi, contain the hormone hCG and can cause a false positive result.
-
Medications: Some medications, such as anti-anxiety medications, antipsychotics, anticonvulsants, Parkinson’s disease medications, diuretics, antihistamines, and methadone, can cause a false positive pregnancy test.
-
Medical conditions: Certain medical conditions, such as molar pregnancy, rare antibodies, and some rare ovarian cysts, can cause a false positive result.
Its important to note that false positive results are rare, and most positive pregnancy tests indicate a viable pregnancy. If you receive a positive result, its important to talk to your doctor about beginning early prenatal care.
