""hCG" is an initialism for "human chorionic gonadotropin". Chorionic refers to the production of hCG from the syncytiotrophoblasts of the chorion which develop into the fetal placenta. Gonadotropin refers to a substance that regulates gonadal activity (for instance, FSH and LH, the two anterior pituitary gonadotropins, are in this class)."
"an alpha (α) moiety that is similar to FSH, LH, and TSH, and a"
"In view of this homology between hCG and other gonadotropins, all commercially-available assay kits test for the beta subunit only. This is to reduce the risk of inadvertently mistaking FH and LSH as part of the hCG fraction."

"Outside the pregnancy setting, it may also be used quantitatively as a tumour marker, to aid in diagnosing a potentially beta-hCG secreting mass (e.g. choriocarcinoma)."
"Beta-hCG levels may also be raised by some ovarian neoplasms (e.g. ovarian embryonal carcinoma, ovarian dysgerminoma), as well as in testicular germ cell tumours (e.g. seminoma, mixed germ cell tumour) 8 and choriocarcinoma. Non-gestational choriocarcinomas, while usually arising from gonadal organs (i.e. ovaries or testes), can arise from extragenital sites as diverse as the pineal gland, mediastinum, liver, gallbladder, retroperitoneum, and urinary tract. There are several case reports of beta-hCG-secreting non-small cell lung cancer (e.g. adenocarcinoma 9 and squamous cell carcinoma)."

"Beta-hCG levels decrease rapidly in the first 1-2 weeks after delivery, termination or complete miscarriage and then the rate of decrease slows down beyond 2 weeks. At 6 weeks levels should be zero."
"NB: gonadotropin is the correct spelling; gonadotrophin is an antiquated spelling that should be avoided."
