Fungus Testing Laboratory

PLEASE NOTE: We are currently unable to perform species identification by DNA sequence analysis on cultures from New York State.

Services offered include: Fungal identification, the in vitro susceptibility testing of antifungal drugs, the measurement of levels of antimycotic agents in biological tissues and fluids, and the evaluation of antifungal properties of potential and new antifungal drugs. The Fungus Testing Laboratory has been particularly active in the screening and testing of newly licensed antifungal antimicrobics for the pharmaceutical industry and serves as the contract laboratory for clinical efficacy studies involving these agents in therapeutic and clinical trials in humans for the major drug companies involved in the development of such antimicrobial agents.

PLEASE NOTE: Yeast identification now offered by MALDI-TOF MS.  Testing is reflexed to routine identification (DNA sequence analysis and phenotypic characteristics) if unable to identify the species by MALDI-TOF MS.
PLEASE NOTE: Beginning December 15, 2021, we will no longer offer DNA probe identification of Coccidioides, Blastomyces, or Histoplasma species.  Identifications of these fungi will be performed by routine identification (DNA sequence analysis and phenotypic characteristics).
PLEASE NOTE: That ketoconazole susceptibility testing will no longer be performed by the Fungus Testing Laboratory after January 14, 2022.
