HelpTest ID: MMLYP Antimicrobial Susceptibility Panel, Yeast, Varies
Infectious
Reporting Name
Susceptibility Panel, YeastUseful For
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)

Testing Algorithm
When this test is ordered, the susceptibility yeast panel will be performed at an additional charge. All yeast submitted will have susceptibility testing performed and billed as appropriate.
Clinical Information
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.
Interpretation
The Clinical and Laboratory Standards Institute method, breakpoints, and interpretive criteria are used.
