beta-human chorionic gonadotropin

β-human chorionic gonadotropin

a 145-amino acid subunit unique to HCG, which has the same α-chain as FSH, LH, and TSH. Pregnancy tests specific for β-HCG are more sensitive because there is no confusion with other gonadotropins secreted by the pituitary.

Beta-HCG (Beta-human chorionic gonadotropin)

A tumor marker associated with testicular cancer and tumors, such as choriocarcinoma and molar pregnancies, that begin in placental cells called trophoblasts.
