Antigen assay with the potential to aid in diagnosis of blastomycosis.
We report results of an immunoassay for Blastomyces dermatitidis antigenuria. Sensitivity was 92.9%, and specificity was 79.3%. Cross-reactions occurred in 96.3% of patients with histoplasmosis, 100% of patients with paracoccidioidomycosis, 70% of patients with penicilliosis marneffei, 2.9% of patients with cryptococcosis, and 1.1% of patients with aspergillosis. Reproducibility was 96.3%. These findings support a potential role for antigen testing in blastomycosis.
