Assessment of the IgA Immunosorbent Agglutination Assay for the Diagnosis of Congenital Toxoplasmosis on a Series of 145 Toxoplasmic Seroconversions

Abstract

A retrospective analysis of 145 medical records from our teaching hospital laboratory showed an overall specificity of greater than 97% for the IgA immunosorbent agglutination assay (ISAGA A) performed on the sera of babies to diagnose congenital toxoplasmosis (CT). These actualized data emphasize the ability of this test to confirm a diagnosis of congenital toxoplasmosis.
