Special Info

Test includes culture for yeasts and molds plus microscopic examination using calcofluor stain. Full identification will be performed routinely on significant yeast isolates. Limited identification is performed on nonsterile sites. In-house susceptibility testing on yeast isolates is performed only upon request and only when clinically indicated. Mold identification will be performed on significant isolates. Some dimorphic molds will require confirmation using DNA probes. Mold susceptibilities are not performed in-house and will be sent to an outside reference lab upon request only. Note any special requests such as rule out Malassezia furfur on the requisition. For hair, skin and nail sources, please use order code ACFSC for culture requests and order code FHSHSM when requesting both fungal culture and smear. If culture is positive for yeast or mold, identification will be performed as mentioned above at an additional charge. Identification CPT codes that may apply include: 87106, 87107, 87149. Antimicrobial susceptibilities are performed as mentioned above, and CPT code 87186 would apply.

Clinical Info

Order Fungal Culture and Smear to rule out fungal infection and identify the causative agent(s). A single negative culture does not rule out the presence of fungal infection.
