Iyini i-β-subunit yamahhala ye-gonadotropin ye-chorionic yomuntu?
I-β-subunit yamahhala iyinhlobo ye-hCG e-glycosylated monomeric eyenziwe yizo zonke izimila eziyingozi ezingezona i-trophoblastic. I-β-subunit yamahhala ikhuthaza ukukhula kanye nomdlavuza wezimila eziyingozi eziyingozi. Uhlobo lwesine lwe-hCG yi-pituitary hCG, ekhiqizwa ngesikhathi somjikelezo wokuya esikhathini kwabesifazane.
Kuhloswe ukuthi kusetshenzisweni mahhalai-β subunit yekhithi yokuhlola okusheshayo ye-chorionic gonadotropin yomuntu?
Le khithi iyasebenza ekutholakaleni kwe-β-subunit yamahhala ye-human chorionic gonadotropin (F-βHCG) kusampula ye-serum yomuntu, efanelekela ukuhlolwa okusizayo kwengozi yabesifazane yokuthwala ingane ene-trisomy 21 (Down syndrome) ezinyangeni ezintathu zokuqala zokukhulelwa. Le khithi inikeza kuphela imiphumela yokuhlolwa kwe-β-subunit yamahhala ye-human chorionic gonadotropin, futhi imiphumela etholakele kufanele isetshenziswe kanye nolunye ulwazi lwezokwelapha ukuze luhlaziywe. Kumele isetshenziswe kuphela ochwepheshe bezempilo.
