What can cause high hCG levels besides pregnancy?

Apart from pregnancy, there are other gynaecological conditions that can cause an elevated serum hCG. Gestational trophoblastic diseases such as hydatidiform moles, gestational trophoblastic neoplasias, and choriocarcinomas are diseases where hCG is elevated and the hCG ratio changes in favour of free hCGβ [9].

What causes hCG levels to rise if 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.

Can you have hCG levels and not be pregnant?

Many women have very low levels of HCG in their blood and urine when they are not pregnant. HCG tests detect elevated levels. Tests may not detect pregnancy until HCG has risen to a certain level. This requirement means tests that detect lower levels of HCG may diagnose pregnancy earlier.

What can raise hCG levels other than pregnancy?

Although the most common cause of an elevated HCG level in females is pregnancy, occasionally, a HCG-secreting tumor is suspected and other conditions such as gestational trophoblastic disease (GTD), nontrophoblastic neoplasms, or a pituitary source of HCG, must be considered.

What is borderline pregnancy?

Will sperm make a pregnancy test positive?

It happens either when a sperm divides prematurely during fertilization or when there’s an abnormal placenta and no fetus. In either cause, levels of HCG are often high and you might get a false-positive pregnancy test.

What color is your urine when you are pregnant?

The more fluids you drink, the lighter the color of the pigment in your urine.

At what hCG level will I miscarry?

Your levels will ultimately go back to 0 mIU/mL. In fact, anything less than 5 mIU/mL is “negative,” so effectively, 1 to 4 mIU/mL is also considered “zero” by doctors. If you have a miscarriage, the time it takes for your levels to go to zero varies based on how high your levels were at time of miscarriage.
