Can drugs cause a false positive pregnancy test?

Can drugs cause a false positive pregnancy test?

Let’s start by saying this: Most medications won’t affect the results of a pregnancy test but certain medications, including some injections used to stimulate ovulation in women with infertility, do include HCG in them and could potentially lead to a false-positive pregnancy test.

Can anything else cause HCG levels?

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.

Can you have high hCG levels and not be 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 produce hCG 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.

Can you still miscarry if your hCG levels are rising?

While knowing hCG levels may be helpful, it is not an absolute indicator that a person will experience pregnancy loss. The risk of pregnancy loss is greatest in the first trimester, which coincides with rising hCG levels.

What happens if you get pregnant before hCG levels return to zero?

It typically takes from one to nine weeks for hCG levels to return to zero following a miscarriage (or delivery). Once levels zero out, this indicates that the body has readjusted to its pre-pregnancy state—and is likely primed for conception to occur again.

How long does a positive line stay on a pregnancy test?

This usually ranges between a couple of minutes up until 10 minutes later. If you see a positive result beyond this time frame, you may be left second-guessing the results. However, the false-positive reading, in this case, is due to something called an evaporation line.
