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)

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.

Differentiation of Candida dublinensis from the biochemically and clinically similar species Candida albicans is performed on request only.
