For the clinical performance, the PCR/ESI-MS method was applied to prospectively collected BAL specimens obtained from patients suspected of, or at high risk for, pulmonary fungal infections. All BAL samples were processed at the Johns Hopkins Hospital Microbiology Laboratory for the detection and identification of fungal pathogens using all standard of care reference tests including direct microscopic examination by calcofluor white staining, fungal culture, galactomannan (positive cutoff value: GMI 0.5), and direct fluorescent antibody (DFA) microscopic examination that is the only method used for the detection of Pneumocystis jirovecii. ./cache/cord-335359-4rcj75tc.txt ./txt/cord-335359-4rcj75tc.txt
