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).
