Fungal (Mould/Yeast) Identification : 0060163

Mnemonic: MC FUNGID

Methodology: Identification
Identification methods may include biochemical, mass spectrometry, or sequencing.
Performed: Sun-Sat
Reported: Varies
Specimen Required: Collect: Actively growing mould or yeast in pure culture.

Specimen Preparation: Transport sealed container with pure culture on agar slant. Place each specimen in an individually sealed bag.

Storage/Transport Temperature: Room temperature. If culture is suspected of being a microorganism listed as infectious substance affecting humans on IATA list, submit specimen according to Biological Substance, Category A, shipping guidelines.

Remarks: Specimen source preferred.

Unacceptable Conditions: Mixed cultures or non-viable organisms. Isolates from environmental sources. Agar plate.

Stability (collection to initiation of testing): Ambient: 4 weeks; Refrigerated: 4 weeks; Frozen: Unacceptable
Note: An additional handling charge will be billed for all organisms submitted for identification that are not in pure culture as indicated in the specimen requirements. Identification of referred isolates is performed and billed by the extent of tests required for identification. When the specimen submitted contains both mould and yeast, both will be identified.

Testing to differentiate between Candida albicans and Candida dubliniensis is performed by request only.

Cryptococcus gattii will be ruled out when routine biochemical testing identifies organism as Cryptococcus neoformans.
 
Organisms submitted for identification are kept for 7 days; if organism fails to grow, the client will be contacted. All original submissions are held until the identification is completed or the test is cancelled.
