title: IgA immunoassay for the diagnosis of bancroftian filariasis.
abstract: In some parasitic infection such as toxoplasmosis, specific IgA is a highly reliable marker of active infection. In bancroftian filariasis, only 10 of 20 (50%) and 3 of 20 (15%) of the microfilaremic patients were positive for IgA anti-Brugia malayi using respectively indirect ELISA and immunocapture ELISA tests. As regard to these low sensitivities, the detection of specific IgA is unlikely to be a useful test for the diagnosis of active Wuchereria bancrofti infection.
