Human Chorionic Gonadotropin (HCG) is a glycoprotein, which is secreted in large quantities by normal trophoblasts.
It is present only in trace amounts in non-pregnant urine and sera, but rises sharply during pregnancy.
HCG is composed of two non-identical, non-covalently linked polypeptide chains designated as the a- and b-subunits.
The a-subunit of HCG is nearly identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), and luteinizing hormone (LH).
A germ cell tumor which is positive for cytokeratin, placental alkaline phosphatase (PLAP) and HCG, but negative for EMA and AFP, is probably a choriocarcinoma.
