Fungal Susceptibility Test (MIC)

Sunquest Code:RESENS  
Synonyms:Fungal Sensitivity; Antifungal Susceptibility; MIC Fungus; Fungus; Yeast Susceptibility
Methodology:Microtiter Panel
Test Includes:Minimal inhibitory concentration of filamentous fungal isolates or yeast isolates to Amphotericin B, Itraconazole, 5-fluorocytosine, Fluconazole, Voriconazole, Micafungin, Caspofungin. Posaconazole and Isavuconazole. Check with laboratory for availability of new antifungal drugs.
Turnaround Time:Performed daily, 0730-1530; availability of result varies with the growth rate of the isolate being tested.
Special Instructions:Indicate ID of organism, as well as which antifungal drugs should be tested: Amphotericin B, Itraconazole, 5-Fluorocytosine, Fluconazole, Voriconazole, Micafungin, Caspofungin, Posaconazole or Isavuconazole. Note: Most filamentous fungi are resistant to fluconazole.

Collection Instructions

Specimen:Test performed on fungal/yeast isolate
Causes for Rejection:Non-viable isolates cannot be tested. Coccidioides immitis isolates will not be tested due to extreme hazards of the growth phase of this agent. Also don't test Histoplasma capsulatum, Blastomyces dermatitidis or dermatophytes.

Processing and Shipping

Specimen Processing:Supply a fresh pure subculture of fungal/yeast isolate on an agar plate or slant. Filamentous fungal isolates should be well-contained (screw-cap tube) for safe transportation. Store at room temperature.
Shipping Instructions:Ship at room temperature.
Test Performed at or Referral Lab Infectious Diseases Diagnostic Laboratory  (UMMC-East Bank)


Reference Range:See interpretive report.
Use:Test susceptibility of yeast and filamentous fungi.
