comparative study between IFAT, COPT, CHR and IDT in the diagnosis of schistosomiasis mansoni

ABSTRACT

Human sera were collected from various localities in Egypt from 103 cases of parasitologically confirmed schistosomiasis mansoni and 20 volunteers free from parasitic diseases. The presence of antischistosomal antibodies were detected in vivo by intradermal test [IDT] and in vitro by IFAT, COPT and CHR. The results showed that the sensitivities of the 4 serological tests ranged from 71%-98% in acute cases and 83.5% -96% in chronic cases. It was observed that IFAT showed the best sensitivity in both acute and chronic cases in general with a percentage of positivity 96%
