Field comparison of circulating antibody assays versus circulating antigen assays for the detection of Schistosomiasis japonica in endemic areas of China

Background Schistosomiasis remains a serious public health problem in affected countries, and routine, highly sensitive and cost-effective diagnostic methods are lacking. We evaluated two immunodiagnostic techniques for the detection of Schistosoma japonicum infections: circulating antibody and circulating antigen assays.
