[Anti-Candida albicans IgM antibody: correlation between immunofluorescence and ultracentrifugation (author's transl)].

The indirect fluorescent antibody (IFA) technique for specific IgM anti-Candida albicans was applied to 158 sera and compared with sucrose density gradient centrifugation. For detection of specific IgM results of both methods were in agreement for 157 sera (99.36%). Specific IgM titers determined with IFA on unfractionated sera followed those found on fractionated sera. The results show that specific IgM anti-C. albicans can be identified and titrated by the immunofluorescent technique.
