【Abstract】 Objective] To assess the value of detecting circulating antigens and antibodies in urine as a noninvasive method for the diagnosis of schistosomiasis. [Methods] A sandwich ELISA and ELISA using McAb were applied to detect circulating schistosomal antigens and specific antibodies in the urine of patients with acute and chronic schistosomiasis. [Results] When the urine samples from 10 cases of acute schistosomiasis and 61 cases of chronic schistosomiasis were examined, the positive rates of circulating antigens and specific antibodies were 60%,40%, and 80%, 60 1%, respectively; when both detection was combined, the positive rates were 100% and 71 7% respectively, whereas a false positive rate of 3% of CAg or CAb was detected in the urine of 100 normal controls. [Conclusion] The detection of circulating antigen in urine is a practicable and noninvasive method for the diagnosis of schistosomiasis.更多还原
