Fungi cause many types of infections, some of which may become serious, especially in immunocompromised and hospitalized patients. The appropriate collection, transport and processing of specimens allows the recovery of fungal organisms and the association of a specific fungus with a disease process.
Remove hairs with forceps, scrape skin or scalp scales,
clip nails and include keratin scrapings. Cleanse skin
with alcohol before scraping. Cleanse feet and hands
before collecting nails. Refrigeration is not recommended
because it can inhibit dermatophytes.
