Test ID FGEN Fungal Culture, Routine

Useful For

Diagnosing fungal infections from specimens other than blood, skin, hair, nails, and vagina (separate tests are available for these specimen sites)

Method Name

Conventional Agar Culture/Macroscopy/Microscopy/D2 rDNA Gene Sequencing/Real-Time Polymerase Chain Reaction (rtPCR)/Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectrometry (MALDI-TOF MS)

Dimorphic Pathogen Identification Confirmation: D2 rDNA Gene Sequencing/rtPCR/MALDI-TOF MS

Reporting Name

Fungal Culture, Routine

Specimen Type

Varies


Ordering Guidance


Nocardia and the other aerobic actinomycetes are not fungi, therefore  a fungal culture should not be ordered. However, these organisms grow well on mycobacterial medium. When infection with this group of organisms is suspected, order CTB / Mycobacteria and Nocardia Culture, Varies.



Shipping Instructions


Specimen should arrive within 24 hours of collection.



Necessary Information


Specimen source is required.



Specimen Required


Specimen Type: Body fluid
