Antimicrobial Susceptibility - Fungal (Yeasts and Molds)
Also known as: MA FUNGAL
Use
This test is used to determine the in vitro susceptibility of fungal organisms, including yeasts and molds, to a range of antifungal agents. Interpretive data include designations like susceptible, intermediate, susceptible dose dependent (SDD), or resistant. The test helps clinicians in selecting appropriate antifungal treatments for infections.
Special Instructions
Not provided.
Limitations
The susceptibility testing of some molds may not be clinically relevant (e.g., Penicillium species or Cladosporium species). Certain antifungal agents might not attain effective concentrations in all body sites, notably in vitreal, cerebrospinal fluid, and urinary tracts. Some fungi, such as Blastomyces dermatitidis and Histoplasma capsulatum, are not tested at ARUP, and specimens are sent elsewhere for testing. Testing is not applicable to isolates from environmental sources.
