KOH Test
The KOH Test (pronounced as K-O-H test), also known as the Potassium Hydroxide Test, is a quick, inexpensive microscopic examination used primarily in the field of dermatology and mycology to diagnose fungal infections.
Etymology
The term "KOH Test" is an acronym derived from the chemical compound used in the test, Potassium Hydroxide (KOH). Potassium is represented by the symbol 'K' from the Latin word 'Kalium'. Hydroxide is a compound made up of an oxygen atom bonded with a hydrogen atom.
Procedure
The KOH Test involves the application of a drop of 10% to 20% potassium hydroxide solution to a sample of the affected skin, hair, or nails. The sample is then heated and examined under a microscope. The KOH dissolves the keratin in the tissue, making it easier to spot the fungal elements.
