Izinketho zokuvavanya
Ukuba ayishiywanga, i-cystic fibrosis (i-CF) ibangela umonakalo ongenakuguquka kumzimba. I-CF yangaphambili ifunyaniswa, unyango olukhawulezayo luya kuqala ukukhusela umonakalo kunye nokunciphisa ukuqhubeka kwesifo. Ngaphambili, abantu bagula kakhulu kwi-cystic fibrosis ngaphambi kokuba kwenziwe i-diagnostic. Ngaphezulu kweminyaka emibini edlulileyo, iimvavanyo zenziwe zivumela ukuxilongwa phambi kokuba uphawu lokuqala luvele.
Uvavanyo lweGenesis
Ukuhlolwa kwe-Genetic yindlela ephela yokuxelela ukuba umntu uphethe umzila we-cystic fibrosis. Kwakhona ngamanye amaxesha kwenziwa ukuba ufumane ukuba umntu unayo i-cystic fibrosis, okanye ukufumanisa ukuba yiyiphi inguquko eyenziwa ngumntu oneCF.
Ukuvavanywa kwangaphambi kokubeleka
Ukuvavanya i-Genetic kunokwenziwa ngokubanzi ukuqinisekisa ukuba umntwana uya kuzalelwa nge-cystic fibrosis. Ukuba isibini esilindeleyo siyazi okanye sikhankanya ukuba singabathwali befayili ephosakeleyo, banokukhetha ukuvavanya ukuba bancede ukuba bakhethe okanye bangaqedi ukukhulelwa. Ukuba isibini siceba ukuqhubeka nokukhulelwa i-CF ukuxilongwa kuya kwaziwa ngaphambi kokuzalwa kwaye umntwana uya kuba nenzuzo yokufumana unyango lokuqala.
Kukho iimvavanyo ezimbini ezingenziwa kwithuba lokubeleka. Zomibini iimvavanyo zingenasiphelo kwaye zithatha inqanaba elincinci lomngcipheko okumele lixoxwe kunye nodokotela ngaphambi kokuvavanya.
I-Chorionic Vampus Sampling (CVS): Inani elincinane leethambo lisuswe kwi-placenta kwaye lithunyelwa kwibhabhi ukuze lichonge ukuba i-GF ifikile .
Olu vavanyo lwenziwa rhoqo ngeveki ye-11 yokukhulelwa.
Amniocentesis: Ixabiso elincinane le-amniotic fluid lisuswa kunye nenaliti kunye nesirinji kwisisu kwaye ithunyelwe kwibhobho ukuze ichane ukuba i-GF ifikile. Olu vavanyo lwenziwa rhoqo ngeveki ye-16 yokukhulelwa.
Ukuzalwa kwintsana
Ukuhlolwa kwesandul 'ukuzalwa akutholi i-CF, kodwa umphumo omuhle uphakamisa ifulegi ebomvu ukuze uqaphele ugqirha ukuba aqhubeke nokuvavanya.
EUnited States, amaninzi amaninzi ngoku aquka uvavanyo lwe-cystic fibrosis kwiimvavanyo zabo zokuzalwa zokuzalwa.
U vavanyo lwe-Sweat
Uvavanyo lwe-sweat lube luvavanyo lwe-gold standard diagnostic test for CF iminyaka emininzi. Uvavanyo lwe-sweat luvavanyo olukhawulezayo, olungabonakaliyo, olungenabuhlungu olulinganisa amanqanaba e-sodium kunye ne-chloride ekhutshwe ngokukhukhuma. Yisilathisi esihle esihle se-cystic fibrosis kodwa ayikho into ekhohlisayo.
