How to confirm the vitiligo diagnostic






wood's lamp





One of the methods through which doctors can confirm the vitiligo diagnosis is by using the Woods Lamp (black light)

This equipment emits ultraviolet light on a wavelength of 365 nanometers, making a vitiligo patient's skin glow yellow green or blue. In contrast, the healhy skin will have no reaction to the UV light

It is used to detect several skin conditions including fungal and bacterial infections and skin coloring changes such as vitiligo

The Woods Lamp test must be conducted in a dark room and the skin area being examined

must not be contaminated with any agents (eg. topical medication, soap, deodorant or makeup). This means washing your hands just before the exam might yield a false positive result

The health care provider will take several precautions such as advising you not to look directly in the ultraviolet light or providing you protective goggles when examining the face


The Woods Lamp examination holds no risk and you won't feel anything during the procedure


This test reveal different colors according to the type of skin disease, which may include:


Golden Yellow > Tinea Versicolor

Pale Green >Trichophyton Schoenleini

Bright Yellow green >Microsporum Audouini or M. Canis

Aquagreen To Blue >Pseudomonas Aeruginosa

Pink To Pinkorange >Porphyria Cutanea Tarda

Ash-Leaf-Shaped Spot >Tuberous Sclerosis

Bluewhite >Leprosy

Pale White >Hypopigmentation

Purplebrown >Hyperpigmentation

Yellow green or blue >Depigmentation, Vitiligo

Bright White >Albinism
