Conventional culture, microscopic exam with fungal-specific stain, manual or automated identification methods and nucleic acid sequence analysis as needed.
The fungal load in a clinical specimen may be low, especially in blood and bone marrow specimens. Specimens with less than the recommended volumes may therefore lead to a false negative result.
Due to high incidence of blastomycosis in this region, a direct fungal exam is performed and billed on all lower respiratory tract and sinus specimens, and on pleural fluids that are submitted for fungal culture with the exception of swab specimens.
No fungal elements observed (fungal smear)
Culture negative for Fungi
