Munhu chorionic gonadotropin (hCG) ihomoni inobudiswa nemuviri wemukadzi panguva yekuzvitakura. HCG inowanikwa pakarepo mushure mekuberekwa uye inokubvumira kuziva kusununguka kwemazuva 4-5. HCG inobudiswa necharion uye inoenderera mberi kukura kusvikira vhiki 12-13 yekudzivirira - iyo yakanyanya kuwanda yehomoni panguva ino ino 90,000 mU / ml, mushure mokunge index inotanga kuderera. Semuenzaniso, chimiro cheHCG pavhiki 19 kakatosiyana mukati meurusi hwe 4720-80100 mU / ml. Maitiro eHCG pamazuva nemavhiki anokubvumira kuongorora kukura kwekuzvitora mumutatu wekutanga, kuti uone kuti zvinogona kuitika sei uye kukurudzira kusakanganisika.
Tsanangudzo yeHCG
Sarudza huwandu hweHCG nenzira dzakawanda. Mhedzisiro yakarurama kwazvo inowanikwa neropa rekuongorora, rinokubvumira kuziva kusununguka kusati kwaitika kunonoka kusvika kumwedzi. Kuongorora mitemo yeHCG yemavhiki mashoma, chiremba ane ruzivo anogona kunyatsotsanangura nguva yehutano uye zvichiita zvirwere ( kufema kwema fetus , kutyisidzika kwekusiya pamuviri).
Pasina kudarika deta inopa kuongororwa kwemuti, kunyange zviripo kuti mishonga yose yekudzivirira pamuviri inotarwa. Zvakakosha kuziva kuti kana tsanangudzo yehomoni mukuongorora ropa paHCG inoita kuti zvikwanise kutevera nguva yekuzvitakura, ipapo urine tsananguro haisi kupa data yakarurama yakadaro.
Mitengo ye beta-hCG kwemavhiki:
- 1-2 vhiki - 25-156 mU / ml;
- 2-3 mavhiki - 101-4870 mU / ml;
- 3-4 mavhiki - 1110-31500 mU / ml;
- Vhiki 4-5 - 2560-82300 mU / ml;
- Vhiki 5-6 - 23100-151000 mU / ml;
- Vhiki 6-7 - 27300-233000 mU / ml;
- Vhiki 7-11 - 20900-291000 mU / ml;
- 11-16 vhiki - 6140-103000 mU / ml;
- 16-21 vhiki - 4720-80100 mU / ml;
- 21-39 vhiki - 2700-78100 mU / ml.
Zvose zvakagadzirwa nemitemo yeHCG, ingave kuongororwa pavhiki 4 kana pamasvondo 17-18, inobatsira pamusana pechirongwa chepamuviri kamwechete. Kana embryos iri maviri kana kupfuura, mahomoni emahomoni achave akawandisa kazhinji. Saka, somuenzaniso, muhutachiona hwekuberekwa kwehupombwe, hCG pamasvondo matatu kusvika muna 2000 mU / ml uye inoramba ichiwedzera kaviri mazuva mashanu. Nokudaro, pamasvondo mashanu kusvika ku6, mutemo weHCG wehutano hwe 50,000 mU / ml unofanirwa kuve yakakosha.
Zvakakosha kuziva kuti pasi reHCG rinogona kuratidza kubviswa kwepamuviri, ndiko kuti, kupera kwe fetus. Kukura kwakakwana kwehomoni kunoratidzawo ectopic pamuviri uye kutyisidzika kwekutapukira. Penguva yemasvondo gumi nemasere kusvika ku16, huwandu hweHCG, iyo inofanirwa kuve yakaenzana ne10 000-35,000 mU / ml, pamwe chete nemigumisiro yemimwe miedzo inoshandiswa kugadzirisa zvirwere mumusana wekuberekwa kwe fetus.
