Examine medium at 24 hours for pH indicator change in medium from yellow to red. Most pathogenic dermatophytes will
produce full color change within 3 - 6 days. Certain strains of Candida albicans are capable of converting indicator to red,
but yeasts can be recognized by their white bacteria-like appearance. Certain nondermatohyte fungi rarely can produce
alkaline products (false-positive results). For definitive identification of isolates, inoculate onto conventional media.
