CERNER / EPIC MNEMONIC: MICRO REF
POE DESCRIPTION: MICROBIOLOGY REFERRAL
CPT CODE:

87186 yeast; 87188 mold

CDM NUMBER: 3451011; 3511023
TEST INFORMATION: The test includes susceptibility testing of a fungal isolate to one or more of the following: 5-fluorocytosine, fluconazole, ketoconazole, amphotericin B, miconazole, nystatin, intraconazole, griseofulvin, and/or clotrimazole.
DAYS PERFORMED:

Monday-Friday, 0700-1400 send out

TURNAROUND TIME: 1-3 weeks
SPECIAL INSTRUCTIONS: The physician MUST specify that the isolate be saved within 3 weeks of the submission of the specimen. The requisition MUST state all current therapy including date and time of the last dosage. The antifungal agent(s) to be tested MUST be specified.
SPECIMEN REQUIREMENTS: Pure culture isolate of patient`s fungal isolate
REJECTION CRITERIA: Isolate discarded prior to the request by the physician to save the isolate for testing, or the isolate fails to grow on subculture.
REFERENCE RANGE: Defined for each antifungal agent
LIMITATIONS OF TEST: The test cannot be performed if the fungus isolated from the patient is non-viable, not available, or fails to grow adequately to obtain a readable endpoint.
REFERRAL LABORATORY:

University of Texas

ADDITIONAL INFORMATION: This test is performed to determine the minimum fungistatic concentration (MFC) susceptibility of a given organism to an antifungal agent. The ordering physician must specify drugs to be tested.
