ABSTRACT
We conducted a prospective study to evaluate the Schisto-fast test as rapid method for diagnosis of active Schistosomiasis. Fifty patients with active Schistosomiasis were diagnosed by detecting Schistosomal eggs in stool, urine and rectal snips, fourteen persons infected with helminthes other than Schistosomiasis[to detect cross-reaction], and eighteen persons as a control group were included in the present study. Schisto-fast test and ELISA for detection of circulating antigen were done before and after anti-bilharzial therapy. The present study showed that Dot- ELISA test was positive in 100% and 68% in patients before and after anti-bilharzial treatment respectively, while ELISA test was positive in 96% and 16% in patients before and after treatment respectively. Also it was found that Dot- ELISA test was positive in 10/18 [55.6%] in normal control, and 57.14% [8/14] of infected control with other helminthes; while ELISA test was negative in normal control and positive in 14.29% [2/14] of the infected controls. It is our conclusion that the Dot- ELlSA test is not a reliable for diagnosis of Schistosomiasis, and ELlSA test can be used in detecting circulating Schistosomal antigen
