CSF Fungal Culture for Coccidiodes

Item Value
Approval req'd? No
Available Stat? No
Utilization Guidelines For diagnosis of yeast and Cryptococcal meningitis, recommended tests are: CSF bacterial culture (yeast, including Cryptococcus neoformans grow well on routine bacterial culture) CSF and serum Cryptococcal Antigen (CrAg)

Sensitivity of CSF Culture for Coccidiodes immitis is limited. Serum and / or CSF serology for Coccidioides (Coccidioides immitis Antibody, Immunodiffusion) are more sensitive than culture and are the recommended first-line diagnostic tests.

The yield of CSF cultures for other dimorphic fungi and invasive molds, including Aspergillus, Blastomyces, Histoplasma and the Zygomycetes (Mucor and Rhizopus) is extremely low. Tissue biopsy, if possible, is the recommended specimen for fungal diagnosis by culture.
