    • Abstract


      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.
