Detection of filarial antigen in different groups of sera was carried out by sandwich as well as inhibition enzyme-linked immunosorbent assays using antibody-coated sticks. Both systems were found to be equally sensitive in detecting antigen in 90% of microfilariae carriers. Incorporation of avidin-biotin in the sandwich assay system increased the sensitivity of antigen detection from 10−6 to 10−16 pg. A 67% decrease in the number of false negative results was observed when the sensitive avidin-biotin inhibition enzyme-linked immunosorbent assay system was used for analysis of filaria blood samples.

Urinary filarial antigen isolated from urine samples of microfilaraemic patients was analysed for its antigenic activity by immunoblotting and enzyme linked immunosorbent assay techniques. SDS-PAGE fractionation of urinary filarial antigen showed 11 protein bands, of which two showed reactivity with immunoglobulin-G fraction of filarial serum immunoglobulin in immunoblotting. Antigenic analysis of SDS-PAGE fractions of urinary filarial antigen by inhibition enzyme linked immunosorbent assay using filarial serum immunoglobulin-G and
