Ukuxilongwa AFP futhi hCG Ukukhulelwa

Kuze kube manje, igazi nokuthumba owesifazane owayezithwele, indaba kakhulu ulwazi, uyakwazi ukunikeza ulwazi olucacile hhayi kuphela mayelana nesimo sakhe sempilo, kodwa futhi kanjani ukuba balolonge nokuthuthukisa umbungu. Ngaphezu kwalokho, ukuhlolwa kwegazi kwembula khona izifo ezithathelwanayo nezenhliziyo kwabesifazane, okuyinto kubalulekile ngoba kusiza ukuvimbela ukubukeka yokuphazamiseka ukukhula kwezitho futhi izinhlelo umbungu.

Ngesikhathi isonto nesithupha yokukhulelwa, kutuswa ukuba kudlule okuthiwa ukuhlolwa kathathu. Ukuze wenze lokhu, kumele unike igazi ukuzimisela AFP futhi hCG ekukhulelweni ezingaba ukubona ingozi nesifo senhliziyo umntwana ongakazalwa, kanye ukuqeda khona ne-Down syndrome, kwezinso chromosomal nezinye kombungu. ukuhlolwa Kathathu wenza esiswini esingenalutho, ihlanganisa ukutadisha ACE, kuba isifundo serum umbungu okhulayo, futhi hCG, iprotheni okungukuthi placenta.

Ake sicabangele ngokuningiliziwe lokho AFP futhi hCG ngesikhathi sokukhulelwa futhi kanjani ukusebenza zabo ziyithinta kanjani enganeni esizayo.

Alpha-fetoprotein (APF) simele amaprotheni okuyinto kuveza esibindini fetus. Lolu cwaningo lokhu amaprotheni kusiza ukucacisa yokulimala ukwakheka kwe-neural tube, urinary futhi izitho zokugaya umbungu, kanye ingasheshi ukuthuthukiswa yayo. Ngosizo ukuhlolwa kwegazi futhi kunqunywe khona chromosomal ukukhubazeka, isifo Down, Turner noma Edwards, ngeziphambeko ukukhula kwezitho zangaphakathi, kanye nezifo ze-placenta. Nokho, ukushintsha kwemigomo ACE kungaba yi ka esingamahlalakhona esinomhlapho noma usongo kwesisu, kanye ubufakazi esesibelethweni okungalungile wakhulula noma khona nokukhulelwa izingane eziningi ngasikhathi. Kwezinye izimo, ongaphakeme ACE izinkomba asikisela ukufa fetus noma ukukhulelwa zamanga. Kunoma ikuphi, kufanele ukuphinda cwaningo, kanye co-pass ultrasound ukutadisha umzanyana kanye amniotic fluid.

Kufanele kuqashelwe ukuthi ekukhulelweni hCG kuyinto hormone ethakwa abesifazane placenta, ohlukanisa kunjalo, kuye ngokuthi yobudala sokukhulelwa, ezingeni zingahluka. Iyehla iyenyuka hCG ezingeni likhomba nokukhulelwa izingane eziningi ngasikhathi, sesatshiswa esingamahlalakhona kwesisu kanye esinomhlapho, futhi kungase kubonise siyilungiselelo ayilungile yokukhulelwa, khona ngesifo sikashukela kwabesifazane, toxicosis kanye pathologies ekuthuthukiseni umbungu.

Kukhona ekhethekile ithebula hCG ngesikhathi sokukhulelwa, esiza ukuze kutholakale izinga evamile le-hormone zonke izigaba yokukhulelwa. Nokho, imithetho hCG kungahluka kancane, lithembela kokubili elabhorethri mayelana cwaningo, kanye yobudala kanye nesisindo yowesifazane, ubuzwe bakhe, izimfanelo umzimba, khona imikhuba emibi. ke Kuyancomeka ukuba uthintane onguchwepheshe, ngoba ngosizo ukuhlolwa kwegazi akunakwenzeka ukwenza ukusazi ngokunembile isifo esikuphethe, udinga luhlolo ezengeziwe.

Ngakho, i-AFP futhi hCG ekukhulelweni, izifundo ezihlanganisa isivivinyo kathathu ukuhlonza abesifazane abasengozini sokuthuthukiswa kwezinso ku-fetus. Kuyadingeka ukuqapha ezingeni la ma-hormone the Dynamics.

Kumele kukhunjulwe ukuthi namuhla kukhona inqwaba amaphutha zocwaningo laboratory. Mayelana 80% imiphumela amanga, futhi abona othile ewunikela ngesikhathi zilethwe kahle sokukhulelwa, ngeziphambeko isisindo nobudala yowesifazane, kanye khona kuwo izifo ezihlukahlukene uhlelo endocrine. Ukwenza ukuhlolwa yayo AFP futhi hCG ngesikhathi ekhulelwe, udokotela ikhumbule zonke lezi umehluko wemisindo nemiqondo yamagama, futhi, uma kunesidingo, uhlongoza ukuba baphumelele isivivinyo yesibili.

Okwamanje, isivivinyo kathathu kabanzi ukucacisa iqembu lobungozi, okubandakanya abesifazane abakhulelwe, ne ukuhlolwa nemingcele zikude kuyinsakavukela. Kodwa musa nje uphatheke kabi, ngoba ukusihlola iyadingeka ukuze uphethwe yini.
