I-chorionic gonadotropin (hCG) yirmone eveliswa ngumzimba wowesifazane ngexesha lokukhulelwa. I-HCG ibonakala ngokukhawuleza emva kokuchumisa kwaye ikuvumela ukuba uqikelele ukukhulelwa iintsuku ezi-4-5. I-HCG ikhiqizwa nge-chorion kwaye iqhubeka ikhula ukuya kwiiveki ezi-12 ukuya ku-13 zokukhulelwa-izinga eliphezulu le-hormone kule mzuzu li-90,000 mU / ml, emva koko isalathisi siqala ukuhla. Ngokomzekelo, umgangatho weHCG ngeveki 19 sele uvele uhluka kwi-4720-80100 mU / ml. Imimiselo yeHCG kwiintsuku kunye neveki ikuvumela ukuba uqaphele ukuphuhliswa kokukhulelwa kwi-trimester yokuqala, ukufumanisa ukusetyenziswa kwezifo kunye nokuphuhliswa kwezinto ezingaqhelekanga.
Inkcazo yeHCG
Misela izinga leHCG ngeendlela ezininzi. Iziphumo ezichanekileyo zifunyanwe nokuhlolwa kwegazi, okukuvumela ukuba ubone ukukhulelwa ngaphambi kokulibaziseka kwimihla. Ukuphanda iinkqubo ze-hCG kwiiveki ezincinci, ugqirha onolwazi unokuqonda ngokuchanekileyo ixesha lokukhulelwa kunye neentsholongwane ezinokwenzeka ( ukutshatyalaliswa komntwana , usongelo lokuphuphuma kwesisu).
Idata echanekileyo inika uhlalutyo lomchamo, nangona kukho kuyo yonke imvavanyo yokukhulelwa ekhaya isekelwe. Kubalulekile ukuba uqaphele ukuba ukuba inkcazo yehomoni ekuhlalutyweni kwegazi kwi-HCG yenza kube lula ukulandela inkambo yokukhulelwa, ngoko uhlalutyo lomchamo aluboneleli ngcaciso echanekileyo.
Iirhafu ze-beta-hCG iiveki:
- 1-2 iiveki - 25-156 mU / ml;
- Iiveki 2-3 - 101-4870 mU / ml;
- 3-4 iiiveki - 1110-31500 mU / ml;
- Iiveki 4-5 - 2560-82300 mU / ml;
- Iiveki ezi-5-6 - 23100-151000 mU / ml;
- 6-7 iiveki - 27300-233000 mU / ml;
- Iiveki ezi-7-11 - 20900-291000 mU / ml;
- Iiveki ezi-11 ukuya ku-16 - 6140-103000 mU / ml;
- 16-21 iveki - 4720-80100 mU / ml;
- 21-39 iiveki - 2700-78100 mU / ml.
Zonke iimigaqo ze-HCG, nokuba zihlalutyo ngeveki 4 okanye kwiiveki ezingama-17 ukuya kweye-18, zifanelekileyo kwikhosi eqhelekileyo yokukhulelwa okukodwa. Ukuba ii-embrosi zimbini okanye ngaphezulu, ama-hormone indices aza kuba ngamaxesha amaninzi. Ngoko, umzekelo, ngokukhulelwa kwesibeleko esiqhelekileyo, i-hCG kwiiveki ezi-3 ukuya kwi-2000 mU / ml kwaye iyaqhubeka iphindwe kabini kwiintsuku eziyi-1.5. Ngaloo ndlela, kwiiveki ezi-5 ukuya ku-6, umgangatho we-HCG womyalelo we-50,000 mU / ml uthathwa njengesiqhelo.
Kubalulekile ukuba uqaphele ukuba i-hCG ephantsi ingabonisa ukupheliswa kokukhulelwa, oko kukuthi, ukutshatyalaliswa komntwana. Ukukhula okwaneleyo kwehomoni kubonisa ukukhulelwa kwe-ectopic kunye nosongelo lokukhulelwa komzimba. Ngethuba leveki ezingama-15 ukuya kwe-16, izinga le-hCG, umgangatho omele ube ngowama-10,000-35,000 mU / ml, ngokudibanisa neziphumo zenye iimvavanyo ezisetyenziselwa ukuchonga i-pathologies ekuphuhlisweni komntwana.
