Ngamanye amaxesha abantu kufuneka baqaphele ukuba badibeneyo kunye nobudlelwane begazi. Ngokuqhelekileyo, le ngxelo iqhutyelwa ukubonisa ubungqina.
Itheknoloji yanamhlanje ikuvumela ukuba uvavanye ubuntwaba ngegazi, amathe, iinwele kunye nezinye, ezibizwa ngokuba yizinto eziphilayo. Olu luhlalutyo oluqhelekileyo, olunokuthi lunokuchaphazela kakhulu ubomi bethu. Uvavanyo lwe-DNA yezobuntwana luqhutyelwa ukuqinisekisa amalungelo omzali, amalungelo okulifa kunye ngamanye amaxesha nokuvavanya ukuxhomekeka kwizifo ezinobunzima.
Indlela yokwenza uhlalutyo lwe-DNA kubantwana?
Namhlanje kulula ukufumana ubungqina bobawo. Ukwenza oku, kufuneka uqhagamshelane nekliniki, enika ezo nkonzo, kwaye unikele ngokuhlalutya kwento ephilayo ye-baby father and child. Indlela elula kukuthatha i-swab emlonyeni (ukusuka ngaphakathi kwesitram), ngelixa i-DNA impahla ifumaneka kumathe. Ngaphandle koko, kunokwenzeka ukudlulisa iinwele (ngokukhawuleza ukukrazula "ukusuka kwingcambu"), amazinyo, izipikili, i-earwax. Uvavanyo lwegazi lufanelekile ukuhlolwa kwezilwanyana, kodwa kulula ukuba oogqirha basebenze ngamathe, kuba ukuhlolwa kwegazi kunokungabi nolwazi emva kokuxilongwa, ukutsalwa komnatha we-bone, njl njl. Isiphumo soviwo lwe-DNA ngokubambisana nawe uya kufumana kwiintsuku ezimbalwa. Ngelo xesha, uvavanyo lungaba lubi, xa umntu engenawo umntwana onama-100% okanye uyise othe tye. Ubunokwenzeka bokugqibela buvela kuma-70 ukuya kuma-99%. Kufuneka kuqatshelwe ukuba idatha yeemvavanyo ze-DNA ibunzima njengobungqina enkundleni kuphela xa kunokwenzeka ukuba u-97-99.9%.
Uvavanyo lwezilwanyana zokukhulelwa
Ngamanye amaxesha kuyimfuneko yokwenza uhlalutyo lwe-DNA ngaphambi kokuzalwa komntwana. Le teknoloji ibonakale kuhlalutyo - ukuhlalutya kofuzo kwangaphambili kwintando yenzeka kuphela emva kokubeletha.
Uvavanyo luqhutywa ngolu hlobo lulandelayo: ubaba otyholwayo unika uvavanyo lwegazi kwi-vein, kwaye iisampula zeDNA zentsholongwane zithathwa kwigazi lomama, apho inani lale mali elaneleyo loviwo sele liqokelelwe iiveki ezi-9-10 zokukhulelwa. Kukho ezinye iindlela zokuthathwa kwezinto eziphathekayo ze-fetal biological material, umzekelo, i-amniotic puncture (extraal fluid extraction). Le ndlela yokumisela ubume be-DNA inokuchaneka okufanayo, kodwa yingozi kakhulu ngenxa yobungozi beengxaki kunye nokuphela kokukhulelwa, ngoko ke oogqirha baninzi bancomela ukuba bangene kulokho kungenelela.
