Standardization of FIAXtm for schistosomiasis using crude cercarial and adult worm antigens

A fluoroimmunoassay (FIAXTM) has been developed for quantitating the antibody response to schistosomiasis by using cercarial and adult worm antigens of Schistosoma mansoni. The FIAXTM assay was calibrated by using an enzyme-linked immunosorbent assay (ELISA) performed with the same antigens. Studies of reproducibility and preliminary data on a battery of sera from proven cases of schistosomiasis an uninfected control sera are presented.
