Reporting Name
Fungal Culture, RoutineUseful For
Diagnosing fungal infections from specimens other than blood, skin, hair, nails, and vagina (separate tests are available for these specimen sites)
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Specimen Type
VariesOrdering Guidance
Nocardia and the other aerobic actinomycetes are not fungi, therefore a fungal culture should not be ordered. However, these organisms grow well on mycobacterial medium. When infection with this group of organisms is suspected, order CTB / Mycobacteria and Nocardia Culture, Varies.
