Toxoplasmosis is one of the common public health problems. The congenital infection is the most serious form of the disease. This work was conducted on 100 serum samples of pregnant women with previous complicated obstetric history suggesting Toxoplasma infection. Anti-Toxoplasma IgG and, IgM antibodies were evaluated using four commercial serological tests: Latex agglutination, IHAT, ELISA and Immuno-Comb test. The results of the study proved that Latex test gave the highest percentage of seropositivity [58.3%], followed by IgG ELISA [55.8%] and Immuno-comb [55%], while IHAT gave a positive result of [50%]. IgM seropositivity was [44.1%] by ELISA and [46.6%] by Immuno-comb. The correlation between all tests was significant
