A Dot Immnunobinding assay (DIB) has been applied to the serodiagnosis of urinary schistosomiasis and its resuls have been compared with those obtained with the Enzyme Linked Immunosorbent Assy (ELISA). The two techniques have been shown to be closely related (p<0.001). DIB however is more economical and can be read in less than 4 hours. It is simple to perform and easily adaptable for field use
