Understanding KOH Staining, Nail in Howrah
What is KOH Staining, Nail in Howrah?
KOH (Potassium hydroxide) staining is a simple, non-invasive test that helps diagnose fungal infections of the nails. Cells are collected from the affected area and examined for signs of fungal infections under a microscope.
A KOH test is recommended for individuals with the following symptoms of fungal infections:
- A localized rash
- Red patches which are ring-shaped with scaly edges
- Rashes that did not respond to or worsened with corticosteroid medications or those that persist for months
A KOH test does not explicitly identify the type of fungus; it only shows that fungus is present. In most cases, knowing precisely the fungus causing the rash may not be necessary. The doctor can make an informed judgment and prescribe treatment.
