Zvakaoma kune munhuwo zvake kufungidzira izvo amai vanouya mune ramangwana kana zvikamu zvekuongorora kwechirongwa che ultrasound kana chimiro chemagetsi mumwana zvakaratidza dambudziko rekuberekwa kwemafuro. Uye kunyange zvazvo pazvikamu zvitatu chete pazviitiko gumi zvakadai kuongororwa kunosimbiswa nekuongororwa kwakajeka, ndiko kudiwa kwekuongorora zvakare kunotyisa vakadzi vane pamuviri vakawanda.
Pfungwa ndeyokuti kuitira kuti arambe kana kutsigira chirwere chinotyisa, zvinokosha kuongorora fetal karyotype, iyo iyo yakawanda yekliniki inoshandisa nzira dzisina kukodzera dzekuenzanisa zvinyorwa zvekudzidza - chorionic villus sampling, amniocentesis (fetal amniocentesis) uye tsvimbo yeropa sampling (cordocentesis). Mukuwedzera kumatambudziko eyo nzira yacho pachayo, inogona kuva nemigumisiro yakaipa kwazvo, iyo inoparadzanisa kubata. Izvi zvinokonzera vamwe vakadzi kusiya urwere hwakadaro uye nokudaro vanozviisa pachena kune chinetso chinotambudza munguva yese yegomba, izvo zvisingagoni asi zvinokanganisa kunyange mwana ane utano hwakakwana.
Nei fetal karyotype kuongororwa?
Mukutarisa kwepabonde mushure mevhiki yegumi nemana yekudzivirira, ultrasound inorayirwa. Pamwe pamwe ne-ultrasound, zviratidzo zvehupenyu hwehupenyu zvinowedzera kuongororwa. Chinangwa chemaitiro aya ndechekutsanangura iyo inonzi inonzi boka risina ngozi. Zvisinei, kuongororwa kwakadaro kunogona kuratidza chikamu chiduku chemukana wehutachiona hwemararamiro uye hazvibviri kuisa chivimbo chekufungidzirwa pamigumisiro yaro. Nokubatsirwa nekuongororwa kwakajeka kwekaryotype ye fetus, zvinokwanisika kugadzirisa nehupamhi hwehutano hunoti chromosomal isingafadzi, iyo iri muzvokurapa inonzi syndromes:
- Kuno;
- Edwards;
- Patau;
- Shereshevsky-Turner;
- Klinefelter.
Noninvasive nzira yekuongororwa kwechromosomal pathologies
Pakupera kwezana remakore rapfuura, fetal DNA yakawanikwa muropa remukadzi ane pamuviri. Zvisinei, makore makumi maviri chete gare gare, nekuvandudzwa kwe nanotechnology, chirongwa cheDNA chekare chisina kuwanikwa chakashandiswa mune mushonga unoshanda. Chinokosha chetsika yacho inosanganisira kuvhara DNA extracellular ye fetus uye amai kubva kune ropa rakawanda raamai uye vozozviona kuti kune chromosomal inenge isina kunaka. Ichi chidzidzo chinonzi kuongororwa kwetrisomy yakakura kana kuongorora kweDOT.
Kubudirira kukuru kwemuedzo weDOT ndeyekuchengeteka kwemukadzi nemwana wake. Mukuwedzera, inogona kuitwa chero ipi zvayo mushure mevhiki yegumi yekuzvitora, uye migumisiro ichave yakagadzirira mukati memazuva gumi nemaviri kubva pa99.7% kuvimba. Kuongororwa kwakadaro kunonyanya kuratidzwa kuvadzimai vari pangozi yekudzivirirwa kwepabonde kutanga. Ima laboratories mashomanana muChina, US uye Russia vanoshandisa nzira iyi mukurapa inoshanda. Munyika yedu, kuongorora kweDOT kunogona kuitwa chete mu laboratori ye "Genoanalyst", iyo nyanzvi yevashandi vekombiki yakadaro. Kuti uone kuwanikwa kwekutsvakurudza kwakadaro kwevakadzi kubva kunzvimbo ipi neipi muRussia, kuunganidza ropa kunogona kuitwa panzvimbo yezvokurapa iri pedyo, mushure mokunge biomaterial inowanikwa kuMoscow kuongororwa kweDOT uchishandisa basa rinokosha rinonyora tsamba. Tora utano hwemwana wako asati aberekwa. Utano kwauri nekuvana vako remangwana!
