The enzyme immunosorbent assay (ELISA) for serologic diagnosis of toxoplasmosis in pregnancy.

Abstract

The enzyme-linked immunosorbent assay (ELISA) is simple, quick, and inexpensive, characteristics that make it particularly suitable for large screening programs. We compared the results obtained by ELISA with those obtained by immunofluorescent antibody test (IFAT), indirect hemoagglutination test (IHAT), and Sabin Feldman Dye test in a group of 105 pregnant women in the course of a screening for toxoplasmosis. Prevalence of IgG antibody titers were not significantly different. ELISA results were particularly close to those of the reference tests (IFAT and Dye test).
