• Ukuhlolwa kobaba kwenziwa kanjani
• Ukuhlolwa kwe-DNA ngenkathi ukhulelwe
• Ungakuthatha kuphi ukuhlolwa kobaba

Ukuhlolwa kobaba luhlobo lokuhlolwa kwe-DNA okuhlose ukuqinisekisa izinga lobudlelwano phakathi komuntu nobaba wakhe ocatshangelwayo. Lokhu kuhlolwa kungenziwa ngesikhathi sokukhulelwa noma ngemuva kokubeletha ngokuhlaziya igazi, amathe noma imicu yezinwele zikamama, ingane kanye nobaba osolwayo.

Izinhlobo eziyinhloko zokuhlolwa kobaba yilezi:

• Ukuhlolwa kokubeletha ngaphambi kokubeletha: kungenziwa kusukela ngeviki lesi-8 lokukhulelwa kusetshenziswa isampula elincane legazi likamama, njengoba i-DNA yesibeletho isivele itholakele egazini likamama, futhi uma iqhathaniswa nezinto zofuzo kababa okusolwa ukuthi zinazo;
• Ukuhlolwa kobunikazi be-Amniocentesis: ingenziwa phakathi komhla ka-14 no-28 wokukhulelwa ngokuqoqa uketshezi lwe-amniotic oluzungeze umbungu bese uwuqhathanisa nofuzo olusolwa ngofuzo lukababa;
• Ukuhlolwa kobaba baseCordocentesis: kungenziwa kusukela ngeviki lama-29 lokukhulelwa ngokuqoqa isampula yegazi embungwini ngentambo yesibeletho bese uyiqhathanisa nofuzo lobaba okusolwa ngalo;
• Ukuhlolwa kobaba be-Corial villus: kungenziwa phakathi kwesonto le-11 nele-13 lokukhulelwa ngokuqoqwa kwezingcezu ze-placenta nokuqhathanisa nezinto zofuzo zikababa osolwayo.

Okuqukethwe kukababa okusolakala ukuthi kungaba yigazi, amathe noma izinwele, kepha-ke amanye amalabhorethri ancoma ukuthi kuqoqwe izinwele eziyishumi ezithathwe empandeni. Uma kwenzeka kushona lowo okusolwa ubaba, ukuhlolwa kobaba kungenziwa kusetshenziswa amasampula egazi avela kumama noma kubaba kamufi.

Ukuhlolwa kobaba kwenziwa kanjani

Ukuhlolwa kobaba kwenziwa ngokuhlaziywa kwesampula elithunyelwe elabhorethri, lapho kwenziwa khona ukuhlolwa kwamangqamuzana okukhombisa izinga lobudlelwano phakathi kwabantu ababehlolwe ngokuqhathanisa i-DNA. Funda kabanzi ngokuhlolwa kwe-DNA.

Umphumela wokuhlolwa kobaba ukhishwa phakathi kwamasonto amabili kuya kwamathathu, kuya nge-laboratory okwenziwa kuyo, futhi unokwethenjelwa ngama-99.9%.

Ukuhlolwa kwe-DNA ngenkathi ukhulelwe

Ukuhlolwa kwe-DNA ngesikhathi sokukhulelwa kungenziwa kusukela ngeviki lesi-8 lokukhulelwa ngokuqoqa igazi likamama, ngoba ngalesi sikhathi i-DNA yesisu ingatholakala ijikeleza egazini likamama. Kodwa-ke, lapho ukuhlolwa kwe-DNA kukhomba kuphela i-DNA yomama, kungadingeka ukuthi uphinde uyiqoqe noma ulinde amasonto ambalwa ukuthi kuqoqwe enye impahla.

Imvamisa evikini le-12 lokukhulelwa, i-DNA ingaqoqwa ngokusebenzisa i-chorionic villus biopsy, lapho kuqoqwa khona isampula lengxenye ye-placenta equkethe amaseli ombungu, elathathwa liyohlolwa elebhu futhi liqhathaniswe nezinto zofuzo umbungu. okuthiwa ubaba. Cishe ngesonto le-16 lokukhulelwa, i-amniotic fluid ingaqoqwa futhi cishe ngesonto lama-20, igazi elivela enkabeni.

Noma iyiphi indlela esetshenziswayo ukuqoqa okokuzalwa kofuzo, i-DNA iqhathaniswa ne-DNA kababa ukuhlola izinga lobudlelwano.

Ungakuthatha kuphi ukuhlolwa kobaba

Ukuhlolwa kobaba kungenziwa ngokuzimela noma ngomyalelo wenkantolo kuma-laboratories akhethekile. Amanye amalabhorethri enza ukuhlolwa kobaba eBrazil yilawa:

• Genomic - ubunjiniyela bamangqamuzana - Ucingo: (11) 3288-1188;
• Isikhungo seGenome - Ucingo: 0800 771 1137 noma (11) 50799593.

Kubalulekile ukwazisa ngesikhathi sokuhlolwa ukuthi ngabe kukhona yini umuntu owafakwa igazi noma umnkantsha ezinyangeni eziyi-6 ngaphambi kokwenziwa kovivinyo, njengoba kulezi zimo umphumela ungangabazeka, ukulungele ukwenza ukuhlolwa kobaba ngokuthi ukuqoqa isampula.
