title: Comparison of indirect immunofluorescence and enzyme-linked immunosorbent assay for detection of toxoplasma antibody.
abstract: Eighty samples of human serum were tested for antibody to Toxoplasma gondii by enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence (IIF). Development of ELISA suggested that accurate results could only be obtained with serial serum dilutions. ELISA and IIF tests showed a significant degree of correlation, but ELISA was found to be more sensitive: 17% of 24 sera showing negative IIF values showed slightly positive ELISA titres.
