Why do non pregnant women have any level of hcg at all? my level is 0.6.

Outside the box: Normally HCG is undetectable in the non-pregnant woman.But that's in a perfect world far, far from here. First, there could be a lab error or contaminant .Next, certain drugs can cause a false positive test.Other various molecules could also interfere with the test. Finally, HCG is sometimes used as a so-called "marker" for rare tumors.Discuss this with your doctor. I bet the test will be repeated

Beta hCG: hCG is produced in small amounts by the pituitary and other organs, including the testis, liver, colon, and in much larger amounts by placental trophoblast and by malignancies such as hydatidiform mole, choriocarcinoma, and germ cell tumors. Hope this helps.
