Chii chinonzi beta hCG?
Sezvinozivikanwa, chorionic gonadotropin ine beta uye alpha subunits. Chinokosha zvikuru ndeye beta-hCG, iyo iyo yakatarwa panguva yekuzvitakura.
Kutsunga kwemajeri ehomoni iyi inokubvumira kuziva kuti kubata kwemazuva maviri kunonoka. Zvisinei, kuti uwane hutano hwakajeka zvinokurudzirwa kuti udzoke zvakare kuongororwa uye uende kune ultrasound.
Chii chinonzi subunit huru yeHCG?
Kwekutanga, kana kuti sezvavanotaura, kutariswa kwepabonde kunogona kuitika pamwana we fetus, funga nezvehuwandu hweropa mumusangano wekusununguka wepasitini weHCG.
Kuongorora uku kunoitwa kwemaawa gumi nemasere kusvika ku14. Izvo zvakakwana mavhiki 11-13. Muchiitiko ichi, sekutonga, izvo zvinodanwa kuedzwa kaviri zvinoitwa, i.e. kunze kwehuwandu hwekusununguka beta-hCG, zvinyorwa muropa zvine chokuita nekuzvitakura kweplasma protein A zvakafanirwa . Kufanana neizvi, ultrasound inoitwawo.
Muchikamu chechipiri chemuviri wakakwana, kuongororwa kunoitwa kubva pamasvondo makumi matanhatu nematanhatu. Chimwe chinhu chakasiyana ndechokuti panguva ino, izvo zvinonzi kuidzwa katatu kunoitwa. Munyaya iyi, pasina beta-hCG, AFP (alfa-fetoprotein) uye pachena isradiol yakaiswa.
Mhinduro yacho inoongororwa sei?
Kuongorora nekuona kukanganisa kunokonzerwa nekugadziriswa kwemukati, kuburitsa kweropa kwekusununguka kwebasa reHCG panguva yekudzivirira kwakagadzwa. Panguva imwe chete iyo yehutoni iyi haisi kugara uye zvakananga inobva pane izwi.
Mumakore matatu ekutanga ekudzivirira, kuwanda kweHCG kunowedzera kaviri. Inosvika pakakwirira pavhiki 7-8 yekutakura fetus (kusvika ku 200 000 mU / ml).
Saka, pamusi we11 kusvika ku12, huwandu hweHCG hunogona kuva 20-90,000 mU / ml. Mushure meizvozvo, zvarinowanikwa muropa remukadzi ane pamuviri zvinotanga kuderera zvishoma nezvishoma, izvo zvinotsanangurwa nechokwadi chokuti panguva iyo yose masangano ehutano anokosha akaumbwa, chete kukura kwavo kunowanzoitika.
Kana tikataura nezvehutano hwe hCG hunochinja mukati memavhiki ekudzivirira, inowanzoitika sezvinotevera:
- 1-2 mavhiki - 25-300;
- 2-3 vhiki - 1500-5000;
- 3-4 mavhiki - 10000-30000;
- 4-5 - 20000 - 100000;
- 5-6 - 50000 - 200000;
- Vhiki 6-7 - 50000-200000;
- 7-8 - 20000 - 200000.
Mushure meizvi, kuiswa kwegonadotropin muropa kunoderera uye pakuguma kwekuzvitakura kuri 10,000-50000 mU / ml.
