Specificity of low anti-Toxoplasma IgG titers with IMx and AxSYM Toxo IgG assays.
Low antibody titers (3 to 6 IU/mL) detected by IMx and AxSYM Toxo IgG assays in serum samples from 264 pregnant women were confirmed by the dye test and a high-sensitivity agglutination test in, respectively, 98.5% and 95.6% of cases, attesting a premunition of these patients.
