Can a pituitary tumor cause a false positive pregnancy test?
Can a pituitary tumor cause a false positive pregnancy test?
Medical conditions. Alongside gestational trophoblastic diseases, which includes molar pregnancy, other medical conditions can cause a person’s hCG levels to rise, even when they are not pregnant. These include: disorders affecting the pituitary gland and hormone levels.
What can cause a false positive blood pregnancy test?

Why do I have HCG in my blood if I’m not pregnant?
An elevated β-hCG in the absence of viable pregnancy can occur for multiple reasons and has a broad differential diagnosis including miscarriage, ectopic pregnancy, pituitary hCG production, trophoblastic disease and phantom hCG.
Does high prolactin affect HCG levels?
Prolactin-secreting pituitary implants alone, on the other hand, while exerting small effects on 3 beta-HSD expression and activity, led to a marked potentiation of the stimulatory effect of hCG on all parameters.
Can a cyst make a pregnancy test positive?
Pregnancy test: A corpus luteum cyst can cause a false positive on a pregnancy test. Ultrasound: This imaging test uses high-frequency sound waves to create an image of your uterus and ovaries.
How accurate is a doctors blood test for pregnancy?

It’s possible to have a positive pregnancy test even if you aren’t technically pregnant. This is called a false positive. It’s sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on.
Can ovarian cysts cause HCG levels to rise?
Conclusion: Mature ovarian cystic teratomas have rarely been reported to secrete HCG. They can be an infrequent source of HCG production and may lead to emergency surgery to treat a suspected extra-uterine pregnancy.
Can hormone imbalance cause false positive pregnancy test?
While there is no conclusive evidence about the same, some of the most common conditions which deem problematic while conceiving include ovarian cysts, kidney infections and UTIs. Thyroid and hormonal imbalance can also make you susceptible to false positives.
Does prolactin affect pregnancy?
Prolactin levels increase during pregnancy causing the mammary glands in a woman’s breast to enlarge in preparation for breastfeeding. Prolactin also helps with the release of milk when the baby is nursing.
Does prolactin affect implantation?
A high enough prolactin level can inhibit the proliferation of luteinizing granulosa cells, and can also interfere with corpus luteum function resulting in luteal phase defect, as well as abnormal implantation, and embryo development [2].
What happens if you have a prolactinoma during pregnancy?
During a normal pregnancy, the production of estrogen increases. If you are pregnant and have a large prolactinoma, these high levels of estrogen may cause tumor growth and associated signs and symptoms, such as headaches and changes in vision.
What does it mean when your prolactin level is low?
Levels are normally low for nonpregnant women and for men. If prolactin levels are higher than normal, it often means there is a type of tumor of the pituitary gland, known as a prolactinoma. This tumor makes the gland produce too much prolactin.
Can blood tests detect prolactin overproduction?
Blood tests can detect the overproduction of prolactin and whether levels of other hormones controlled by the pituitary are within the normal range. Women of childbearing age also will have a pregnancy test.
What are the results of surgery for prolactinoma of the brain?
The results of surgery depend a great deal on tumor size and prolactin levels as well as the skill and experience of the neurosurgeon. The higher the prolactin level before surgery, the lower the chance of normalizing serum prolactin.
