Iyini i-beta hCG?
Njengoba kuyaziwa, i-chorionic gonadotropin iqukethe i-beta ne-alpha subunits. Okuyingqayizivele kunazo zonke i-beta-hCG, izinga elinqunywe ngesikhathi sokukhulelwa.
Ukunqunywa kokuhlushwa kwaleli hormone kukuvumela ukuba ubone ukuthi ukukhulelwa kwezinsuku ezingu-2-3 ukubambezeleka. Kodwa-ke, ukuze uthole ukuxilongwa okunembile kunconywa ukuthi kuphinde kuqhutshwe ukuhlaziywa futhi kutholakale i-ultrasound.
Iyini i-subunit yamahhala ye-hCG?
Ngaphambi kokuqala, noma njengoba besho, ukuxilongwa ngaphambi kokubeletha kokubeletha okungenzeka kunesifo somntwana, cabanga ngezinga legazi ku-sub-ata ye-hCG yamahhala.
Lokhu kuhlaziywa kwenziwa isikhathi semasonto angu-10-14. Okulungile ngamaviki angu-11-13. Kulesi simo, njengoba umthetho, okuthiwa ukuhlolwa okuphindwe kabili kwenziwa, isb. ngaphezu kwezinga le-beta-hCG yamahhala, okuqukethwe egazini okuhlobene nokukhulelwa kweprotheni ye-plasma A kunqunywa . Ngokufanayo nalokhu, i-ultrasound nayo yenziwa.
Ku-trimester wesibili yokukhulelwa okujwayelekile, ukuhlaziywa kwenziwa kusukela emavikini angu-16 kuya kwangu-18. Isici esihlukile ukuthi ngalesi sikhathi, lokho okuthiwa ukuhlolwa kathathu kwenziwa. Kulokhu, i-beta-hCG yamahhala, i- AFP (i-alfa-fetoprotein) ne-estradiol yamahhala inqunywa.
Imiphumela ihlolwe kanjani?
Ukuze kuhlolwe futhi kubone ukuhlukunyezwa okungenzeka kokuthuthukiswa kwe-intrauterine, okuqukethwe kwegazi kwe-beta subunit yamahhala ye-hCG ngesikhathi sokukhulelwa kwakhiwe. Ngesikhathi esifanayo izinga le-hormone aliyona njalo futhi ngokuqondile lixhomeke kulelo gama.
Esikhathini sokuqala sokuqala kokukhulelwa, ukuhlushwa kwe-hCG kwanda cishe okuphindwe kabili. Ifinyelela phezulu ekupheleni kweviki eli-7-8 lokuzala ingane (kuze kube ngu-200 000 mU / ml).
Ngakho-ke, ngeviki le-11-12, izinga leHCG lingaba ngu-20-90,000 mU / ml. Ngemuva kwaloko, okuqukethwe kwayo egazini labesifazane abakhulelwe kuqala ukuhla kancane kancane, okuchazwa ukuthi ngaleso sikhathi zonke izinhlaka zomzimba ezibalulekile zakhiwe, kuphela ukukhula kwabo kancane kancane.
Uma sikhuluma ngokuthi izinga leHCG lishintsha kanjani phakathi kwamasonto okukhulelwa, ngokuvamile lwenzeka kanje:
- 1-2 amasonto - 25-300;
- Iviki 2-3 - 1500-5000;
- 3-4 amasonto - 10000-30000;
- 4-5 - 20000 - 100000;
- 5-6 - 50000 - 200000;
- 6-7 amasonto - 50000-200000;
- 7-8 - 20000 - 200000.
Emva kwalokhu, ukuhlushwa kwe-gonadotropin egazini kwehla futhi ekupheleni kokukhulelwa kungu-10,000-50000 mU / ml.
