Culture, Fungus, Skin, Hair or Nails
Use
This test is used to detect and identify fungi from superficial sites—skin, hair, or nails. Identifying the specific fungal species can guide appropriate antimicrobial therapy and confirm dermatophyte or other fungal infections.
Special Instructions
Use specimens such as basal hairs, skin scrapings from the active peripheral edge of lesions, or nail scrapings in a sterile, leak‑proof container. Cleanse skin with alcohol before scraping; refrigeration is not recommended as it may inhibit dermatophyte growth.
Limitations
Cultures may take several weeks and false-negative results can occur if specimens are inadequate or if the patient has used antifungal treatment recently. Sterile hyphae may indicate nondiagnostic growth or contaminant; molecular testing may be required.
