Wood's lamp test - of the scalp

Overview

A Wood's lamp is a light that uses long wave ultraviolet light. When an area of scalp that is infected with tinea (a type of ringworm fungus) is viewed under a Wood's light, the fungus may glow. This test may be done to detect the presence of a fungal scalp or skin infection.
