Specimen Requirements

Collection Onsite

HAIR: Using sterile forceps, pluck fluorescent hairs, or non-fluorescent hairs which are broken off and appear diseased, with sterile forceps. If diseased hair stubs are not apparent, scrape the edges of the scalp lesion with a sterile scalpel. SKIN: Cleanse skin lesions first with 70% alcohol to reduce bacterial and saprophytic fungi. Scrape from the outer edges of skin lesions. NAILS: If infections of the nails, scrape out the friable material beneath the edge of the nails, or scrape or clip off portions of abnormal appearing nail and submit for examination and culture. Do not add saline or any other fluid to the container. Specify current antibiotic or antifungal therapy, and clinical diagnosis. For optimum recovery, send directly to the Microbiology Laboratory. Store and transport specimen at room temperature. Do not refrigerate or incubate.
