DETECTION OF ANTITOXOPLASMA IMMUNOGLOBULIN-A ANTIBODIES BY PLATELIA-TOXO IGA DIRECTED AGAINST P-30 AND BY IMX-TOXO IGA FOR DIAGNOSIS OF ACQUIRED AND CONGENITAL TOXOPLASMOSIS

Platelia-Toxo IgA and IMx Toro IgA assays were used with 260 serum sam ples, of which 93 were from seroconverted patients, 58 were from 21 co ngenitally infected children, and 109,were from uninfected patients, t o detect anti-P30 immunoglobulin A antibodies. Because of its enhanced sensitivity, Platelia-Toxo IgA is more efficient in diagnosing acute or congenital toxoplasmosis. IMx Toro IgA must not be used to diagnose congenital toxoplasmosis.
