ⓘ Hair perforation test

The hair perforation test, also known as an in vitro hair perforation test, is a laboratory test used to help distinguish the isolates of dermatophytes, such as Trichophyton mentagrophytes and its variants. The test is performed by placing an organism into a Petri dish containing water, yeast extract, and hair. The Mayo Clinics mycology laboratory has identified five common dermatophytes, Microsporum gypseum, Microsporum canis, Trichophyton rubrum, Trichophyton mentagrophytes, and Trichophyton tonsurans.
