About this service

Potassium Hydroxide (KOH) preparation for miscellaneous samples is a rapid microscopic test for the preliminary detection of fungal elements (hyphae or yeast cells) in clinical samples other than hair or nails. The KOH solution (10-20%) dissolves and digests human cells and tissues in the sample, while keeping fungal structures intact and clear for microscopic examination. The sample type should be clearly specified by the requesting physician or clinician.
