Inkcazo eneenkcukacha
Isifo se-Chagas yintsholongwane, intsholongwane ye-zoonotic yi-protozoan T. cruzi, ebangela ukusuleleka kwenkqubo yabantu ngokubonakaliswa okubukhali kunye ne-sequelae yexesha elide.Kuqikelelwa ukuba i-16-18 yezigidi zabantu bosuleleka kwihlabathi jikelele, kwaye malunga nama-50,000 abantu bafa nyaka ngamnye ngenxa yesifo esingapheliyo seChagas (World Health Organization).Ukuhlolwa kwe-Buffy coat kunye ne-xenodiagnosis esetyenziswa njengeyona ndlela ixhaphakileyo ekuxilongweni kwe-acute T. cruzi infection.Nangona kunjalo, zombini ezi ndlela zidla ixesha okanye zingabi novakalelo.Kutshanje, uvavanyo lwe-serological lube yeyona nto iphambili ekuchongeni isifo sikaChagas.Ngokukodwa, iimvavanyo ezisekelwe kwi-antigen eziphinda-phindaneyo zisusa iimpendulo ezingezizo ezibonakala ziqhelekile kwiimvavanyo ze-antigen zomthonyama.I-Chagas Ab Combo Rapid Test luvavanyo lwe-antibody olukhawulezayo olufumanisa izilwa-buhlungu ze-IgG i-T. cruzi kwimizuzu eyi-15 ngaphandle kweemfuneko zesixhobo.Ngokusebenzisa i-T. cruzi specific recombinant antigen, uvavanyo lubucayi kakhulu kwaye luthe ngqo.
