Kuongororwa kwe AFP uye hCG panguva yekudzivirira

Kusvika iye zvino, ropa romudzimai ane pamuviri ndiro rinonyanya kudzidzisa, rakakwanisa kupa ruzivo rwakajeka kwete chete nezvehutano hwehutano hwake, asiwo nezvekuti mwana akabatwa sei uye anovandudza. Uyezve, kuongororwa kweropa kunogona kuratidzira kuvapo kwezvirwere uye zvirwere mumuviri wemukadzi, iyo inotora basa rinokosha, sezvo inobatsira kudzivirira kuonekwa kwevhiringidzi mukukudziridza nhengo dze fetal uye zvirongwa.

Pamasvondo gumi nematanhatu ekuberekwa, zvinokurudzirwa kuti uende kunonzi inonzi katatu. Kuti uite izvi, zvakakosha kugovera ropa pakusarudza kwe AFP uye hCG panguva yekuzvitakura , izvo zvinogona kuisa njodzi yekuva nehutano hwemwoyo mumwana anouya, uyewo kusabvisa kuvapo kweArt's syndrome, chromosomal kusagadzikana uye zvimwe zvisiri izvo. Chiyero chechitatu chinowanikwa pasimba risina chinhu, rinosanganisira kuongorora kwehuwandu hweACE, kureva, kuongorora serum yekukura mumucheche, uye HCG, ndiko kuti, proteine ya placenta.

Ngationgororei zvakajeka zvinonzi AFP uye hCG panguva yekudzivirirwa uye kuti matanho avo ane simba sei kubudirira kwevana remangwana.

Alpha-fetoprotein (ACE) ipuroteni inoberekwa nechiropa che fetal. Kuongorora puroteni iyi kunobatsira kuona zviremera mukuumbwa kwee-neural tube, urogenital system uye nhengo dzekudya dzomukomana, uyewo apo kukura kwayo kunonoka. Nekubatsirwa kweropa rekuongorora ropa, kuvepo kwechirwere chechiromosomal, zvirwere zveAnder, Turner kana Edwards, kusakanganiswa mukugadzirwa kwenhengo dzomukati, uyewo zvirwere zvepentcenta zvinotarirwawo. Kunyange zvakadaro, kuchinja muhurukuro dzeACE kunogona kuva mugumisiro wekushaya kukwana kana kutyisidzika kwekusununguka kwepamuviri, uyewo kuratidza kutaura kusina kutenderwa kwekuita pamuviri kana kuti kuvapo kwekuita pamuviri. Mune zvimwe zviitiko, zvikamu zveACE zvakaderera zvinoratidza kufa kwekufa kana kuberekwa kwenhema. Chero mamiriro ezvinhu, zvakakosha kudzokorora chidzidzo, pamwe chete pamwe chete kugoverwa ultrasound, kuongorora kwembilical cord uye amniotic fluid.

Izvo zvinofanira kuonekwa kuti hCG mumadzimai ane pamuviri ihomoni inoberekwa ne-placenta yemukadzi, saka, zvichienderana nenguva yehutumbi, huwandu hunosiyana. Kuchinja kwehuwandu hweHCG kunogona kushandiswa kutonga pamuviri wekuzvarwa kwakasiyana-siyana, kutyisidzika kwekusununguka kwepamuviri uye kusagadzikana kwakanyanya, uye kunogonawo kuratidza kuumbwa kwekudzivirira kusina kukodzera, kuvapo kwechirwere cheshuga mumukadzi, toxicosis uye chirwere chekudzivirira kwemukati.

Kune tafura yakanakisisa yeHCG panguva yekuzvitakura, iyo inobatsira kunyatsoona hutano hwemahomoni pazvikamu zvose zvepamuviri. Zvisinei, mitemo yeHCG inogona kusiyanisa zvimwe, inobva kune yeb laboratory iyo yakaitisa chidzidzo, uye pamusoro pezera uye kuyerwa kwemukadzi, ukama hwake, hunhu hwehupenyu, kuvapo kwezviito zvakaipa. Nokudaro, zvinokurudzirwa kutaurirana neyanyanzvi, nokuti kuburikidza nerubatsiro rwekuongorora ropa hazvigoneki kuongorora zvakajeka, kumwe kuongorora kunodiwa.

Nokudaro, AFP neHCG panguva yekuzvitakura, iyo inosanganiswa mumuedzo unoverengeka, kubvumira kuziva vakadzi vari pangozi yekukura mushure mekudzivirira vana. Pano iwe unofanirwa kutarisa uwandu hwemhomoni mune dynamics.

Inofanira kurangarirwa kuti nhasi kune zvikanganiso zvakawanda muongororo ye laboratori. Inenge 80% inowira pamigumisiro yemanyepo, uye inotariswa apo kuberekwa kusina kururama, kutakura uye zera remukadzi, uye kana ane zvirwere zvakasiyana-siyana zvegadziriro ye endocrine. Kana tichiongorora AFP neHCG panguva yekuzvitakura , chiremba anofunga nezvemavara ose aya, uye kana zvichidikanwa, anopa kuongorora kwechipiri.

Pari zvino, kuedza katatu kunowanzoshandiswa kusarudza boka rekukuvadza, iro rinosanganisira vakadzi vane pamuviri vane test scores kure nezvinodiwa. Asi usakurumidza kugumbuka, nokuti kusimbisa chirwere chakakodzera kunoda kuongorora zvakare.
