BHCG - Quantitative

Message
Human chorionic gonadotropin (hCG) is a glycoprotein hormone, produced by the placenta.  This hormone is an excellent marker for pregnancy.  Healthy, non-pregnant individuals have low to undectable hCG levels; however, hCG, originating from the pituitary gland, can be found at detectable levels in peri- and post-menopausal women.
