Specificity of the enzyme-linked immunosorbent assay (ELISA) for Toxoplasma IgG antibody

Abstract
An ELISA developed for Toxoplasma IgG antibody was demonstrated to be more sensitive than the current reference tests, the indirect haemagglutination antibody test (IHAT) and the indirect immunofluorescence test (IIFT). No additional cross reactions were found in the ELISA with sera from patients with other parasitic infections, and there was no interference due to the presence of either rheumatoid factor or antinuclear antibodies.
