Yeast Only, Culture
Also known as: Blood Culture, Fungus, Culture, Fungus (Mycology), Fungus Culture, Blood
Use
Blood: Isolate and identify yeast; establish the diagnosis of fungemia, fungal endocarditis, and disseminated mycosis in patients at risk for fungal infections
Special Instructions
If a yeast is isolated, it will automatically reflex to identification. Cultures are incubated for one week before a final report is issued. Proper specimen collection and handling are important to avoid contamination with commensal organisms. Specify the source of the specimen and include any relevant clinical information to ensure accurate results.
Limitations
A single or even multiple negative fungal blood cultures do not exclude disseminated fungal infection. In cases where a deep fungal infection is strongly suspected yet blood cultures are negative, obtaining a biopsy of the appropriate tissue and/or bone marrow aspiration for sections and culture should be considered. This culture methodology will not recover certain filamentous fungi such as Histoplasma capsulatum, Blastomyces dermatitidis, or Coccidioides immitis, nor dermatophytes like Trichophyton, Microsporum, and Epidermophyton. It is not recommended for sterile body sites, corneal scrapings, or surgically-collected specimens.
