Quick Answer: Can Hormones make a pregnancy test positive?

Can a pregnancy test be positive because of hormones?

When you get pregnant, your body produces a hormone called human chorionic gonadotropin, or hCG. Home pregnancy tests look for that hormone in your urine. If hCG is present, you should get a positive test result when you pee on a stick.

Can hormones cause false positive pregnancy test?

When a pregnancy ends, hCG levels begin to recede, but it’s a slow process. The hormone can remain in your blood and urine for up to six weeks following the end of the pregnancy. It’s possible to have a false-positive test until your hCG levels return to their prepregnancy state.

What hormone causes a positive pregnancy test?

Pregnancy tests check your pee or blood for a hormone called human chorionic gonadotropin (hCG). Your body makes this hormone after a fertilized egg attaches to the wall of your uterus. This usually happens about 6 days after fertilization. Levels of hCG rise quickly, doubling every 2 to 3 days.

Why would I get a positive pregnancy test and then a negative?

The hook effect happens when you have too much hCG in your blood or urine. How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. Rather than two lines saying positive, you get one line that incorrectly says negative.
