ABSTRACT
Sera of 600 asymptomatic pregnant women were tested by IHAT for toxoplasma antibodies. The positive reactors were further tested by IFAT and direct agglutination test [DAT]. The prevalence of toxoplasma antibodies was found to be 27.3% by IHAT, and 58.5% of those found positive were also positive by IFAT, while only 51.8% of them were positive by DAT with 71.34% degree agreement between both tests. So, IFAT was found to be more sensitive than DAT in reference to IHAT and is recommended as a confirmatory test for those found positive on screening by IHAT, DAT, compared to IFAT, gave 69.7% sensitivity and 73.5% specificity. Results support previous findings that IHAT, IFAT, and DAT measure different antibodies of Toxoplasma gondii
