Fungal Culture : 0060149

Mnemonic: MC FUNG

Methodology: Standard reference procedures for fungal culture. Standard reference procedures for identification and/or ITS rDNA Sequencing. DNA probes available for Histoplasma, Coccidioides, and Blastomyces
Performed: Sun-Sat
Reported: Positive cultures are reported as soon as detected
Preliminary negative within 3 weeks
Final negative within 5 weeks
Specimen Required: Collect: Material or fluid from any body site, EXCEPT blood, fecal, genital, hair, nails, oral, skin, and urine.

Specimen Preparation: Place each specimen in a separate, individually sealed bag. (Min: 1 mL fluid) A single specimen may be cultured for both bacteria and fungi. Also acceptable: Swabs (but sub-optimal for recovery of fungi).

Storage/Transport Temperature: Specimens from a sterile body site (fluids, tissues, etc.): Room temperature.
Specimens from a non-sterile site (respiratory, GI tract, etc.):
Refrigerated.
If CSF cannot be transported within eight hours, hold CSF at 35°C until the time of transport.

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Remarks: Specimen source required. Indicate if Malassezia furfur is suspected. Special media must be used for the cultivation of this yeast.

Unacceptable Conditions: Catheter tips.

Stability (collection to initiation of testing): Ambient: 24 hours; Refrigerated: 1 week; Frozen: Unacceptable
Reference Interval:
Culture negative for fungus.
Note: If Histoplasma, Coccidioides, or Blastomyces is the presumptive diagnosis, a DNA probe will be added for confirmation at an additional charge per probe.

Identification performed on mould isolates. Limited yeast identification performed from non-sterile sites. Identification of moulds and/or yeasts on positives is billed separately from culture.

Fungal smear must be ordered separately.  Refer to Fungal Stain, KOH with Calcofluor White (ARUP test code 2004589).
