Kodi beta hCG ndi chiyani?
Monga momwe tikudziwira, chorionic gonadotropin ili ndi beta ndi alpha subunits. Chodziwika kwambiri ndi beta-hCG, mlingo umene umatsimikizika pa nthawi ya mimba.
Kutsimikiza kwa ma hormone amakulolani kuti mudziwe kutenga mimba kwa masiku 2-3 kuchedwa. Komabe, kuti mumvetse bwino molondola ndikulimbikitsanso kuti muyambe kufufuza ndikuyesanso ultrasound.
Kodi gawo laulere la hCG ndi lotani?
Kwa nthawi yoyamba, kapena ngati akunena, ataphunzira kuti ali ndi kachilombo koyambitsa matenda a mwana, ganizirani mlingo wa magazi mu subunit yaulere ya hCG.
Kufufuza uku kumachitika kwa nthawi ya masabata 10-14. Zomwe zili bwino ndi masabata 11-13. Pankhaniyi, monga lamulo, zomwe zimatchedwa kuyesedwa kawiri zikuchitika, i.e. Kuwonjezera pa mlingo wa ufulu wa beta-hCG, zomwe zili m'magazi zokhudzana ndi mimba ya mapuloteni a A A yatsimikiziridwa . Kufanana ndi izi, ultrasound ikuchitanso.
Mu trimester yachiwiri ya mimba yabwino, kufotokoza kumachitika kuyambira masabata 16 mpaka 18. Chinthu chosiyana ndi chakuti pakadali pano, chomwe chimatchedwa kuyesedwa katatu chikuchitika. Pankhaniyi, ufulu wa beta-hCG, AFP (alfa-fetoprotein) ndi ufulu wa estradiol umatsimikiziridwa.
Zotsatira zake zimayesedwa motani?
Pofufuza ndi kuzindikira kuti pali zovuta zowonongeka kwa intrauterine, magazi okhudzana ndi ma subunit a ufulu wa hCG pa nthawi ya mimba atakhazikitsidwa. Pa nthawi yomweyi mlingo wa hormone siwukhazikika ndipo umadalira nthawi yomweyo.
Mu mimba yoyamba ya mimba, kuchuluka kwa hCG kumawonjezeka pafupifupi 2. Ifika pachimake pa sabata 7-8 yobereka mwana (mpaka 200,000 mU / ml).
Choncho, pa sabata la 11-12, mlingo wa hCG ukhoza kukhala 20-90,000 mU / ml. Pambuyo pake, zomwe zili m'magazi a amayi omwe ali ndi pakati zimayamba kuchepa pang'onopang'ono, zomwe zimafotokozedwa ndi mfundo yakuti panthawi imeneyo zipangizo zonse zogwirira ntchito zakhazikitsidwa, koma kukula kwawo kumakhala kochepa.
Ngati tikulankhula za momwe msinkhu wa hCG umasinthira pa masabata a mimba, nthawi zambiri zimakhala motere:
- Masabata 1-2 - 25-300;
- 2-3 sabata - 1500-5000;
- Masabata 3-4 - 10000-30000;
- 4-5 - 20000 - 100000;
- 5-6 - 50000 - 200000;
- Milungu 6-7 - 50000-200000;
- 7-8 - 20000 - 200000.
Pambuyo pake, kulemera kwa gonadotropin m'magazi kumachepa ndipo kumapeto kwa mimba ndi 10,000-50000 mU / ml.
