Identification of certain false-positive results in the Cand-Tec test for candidal antigen

Abstract

By repeated testing of sera after heating (56 degrees C, 15 min) certain false-positives in the Cand-Tec test can be identified from the thermo-resistance of the reaction. True titers are drastically reduced by such pretreatment of sera. The thermostable antigen giving rise to falsely positive agglutination is not identical with mannan.
