Testing Algorithm
When this test is ordered, the reflex test may be performed and charged.
Method Name
Conventional broth culture technique with identification by macroscopic and microscopic morphology, nucleic acid hybridization probes, D2 rDNA gene sequencing, real-time polymerase chain reaction (rtPCR), or MALDI-TOF mass spectrometry. Dimorphic pathogen identification is confirmed using molecular methods (ie, nucleic acid hybridization probes, D2 rDNA gene sequencing, rtPCR or MALDI-TOF mass spectrometry).
(PCR is utilized pursuant to a license agreement with Roche Molecular Systems, Inc.)

Clinical Information
Due to the high mortality rate from fungemia, the expeditious detection and identification of fungi from the patient's blood can have great diagnostic prognostic importance. Risk factors for fungemia include, but are not limited to, extremes of age, immunosuppression, and those individuals with burns or indwelling intravascular devices.
