HCG (Total β-HCG)

Human chorionic gonadotropin (hCG) is a hormone produced by the syncytiotrophoblast, a portion of the placenta following implantation. The presence of hCG is detected in pregnancy tests. Some cancerous tumors produce this hormone , therefore, elevated levels measured when the patient is not pregnant can lead to a cancer diagnosis.
