hCG Testing

Human chorionic gonadotropin (hCG) is produced at elevated levels during pregnancy as well as in gestational trophoblastic disease and due to some germ cell tumors. Additionally, hCG concentrations of a pituitary origin are sometimes detected in peri- and postmenopausal women.

Many female patients are tested for hCG before medical procedures or administration of medication that may harm a fetus. The interpretation of low-level hCG elevation in these females is problematic; such elevations might be benign or might represent malignancies such as gestational trophoblastic disease.
