Fungal Identification

Fungal Identification

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

The Fungus Testing Laboratory is an academic reference laboratory providing fungal identification services. We welcome discussion during any phase of the identification process, and appreciate receiving clinical information that may facilitate documentation of an organism as the etiologic agent.

 

Specimen Requirements:

Isolates must be submitted in pure culture on a slant. Any medium that supports the growth of the organism is acceptable.

Mould Identification CPT 87107 AND 87153

Methods: Phenotypic/morphologic characteristics and DNA sequence analysis

  • Clinical isolates are determined to the species level whenever possible for appropriate patient management. To accomplish this, DNA sequence analysis is routinely combined with morphology and phenotypic characteristics in order to determine species identity. As we continue to further our understanding of the differences between fungal pathogens and susceptibility to antifungal agents, this level of identification is becoming increasingly important for determining appropriate therapeutic options. Thus, we strive to provide the most extensive identification possible while also providing results in a timely fashion.

Yeast Identification CPT 87106 AND 87153

Methods: Phenotypic/morphologic characteristics, MALDI-TOF MS, DNA sequence analysis

The FTL utilizes a variety of tests to arrive at a final yeast identification. Current methods include one or more of the following:

  • Clinical isolates are determined to the species level whenever possible for appropriate patient management. To accomplish this, matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) or DNA sequence analysis are combined with morphology and phenotypic characteristics in order to determine species identity.
