Determining in vitro quantitative antifungal susceptibility (minimum inhibitory concentration) of non-fastidious yeast
As an aid in the management of certain circumstances, such as:
-Refractory oropharyngeal infections due to Candida species in patients who appear to be experiencing therapeutic failure with standard agents at standard doses
-Invasive infections due to Candida species when the utility of azole antifungal agents is uncertain (eg, when the infection is due to a non-Candida albicans organism)
Antifungals included in the assay are amphotericin B, anidulafungin, caspofungin, fluconazole, itraconazole, isavuconazole, rezafungin, micafungin, posaconazole, and voriconazole.

Candida species are the fourth leading cause of nosocomial infections and are frequent causes of community-acquired infections.
Antifungal susceptibility testing may aid in the management of patients with invasive infections due to Candida species or patients who appear to be experiencing therapeutic failure.
The Clinical Laboratory Standards Institute has approved the use of a broth microdilution method for determining the susceptibility of Candida species.
Results reported in mcg/mL
The Clinical and Laboratory Standards Institute method, breakpoints, and interpretive criteria are used.
The assay cannot be used for minimum inhibitory concentration determinations for the dimorphic yeast or filamentous fungi.

Yeast susceptibility is determined by colorimetric microdilution broth method using TREK Sensititre YeastOne Y011 Susceptibility Plate. Each plate is setup with appropriate dilutions of antifungal agents and a colorimetric indicator. After inoculation with a standardized suspension of organism in inoculum medium and incubation at 35 degrees C for 24 to 48 hours; the minimum inhibitory concentrations for the test organism are determined by observing the lowest antifungal concentration showing inhibition of growth as evidenced by no color change of the test medium.(Clinical and Laboratory Standards Institute [CLSI]: Performance Standards for Antifungal Susceptibility Testing of Yeasts. 2nd ed.
