Diagnosis and tests of Vitiligo
Reading time: 1 min
The diagnosis of vitiligo is mainly clinical; that is, by a physical examination and by analysing the symptoms, signs and medical history of the patient.
Additional diagnostic tests are:
Wood’s lamp. It’s a source of an ultraviolet light that makes areas without melanocytes appear bright white.
Skin biopsy. Although not usually necessary, if performed, it reveals a lack of melanocytes in the deepest layer of the skin.
Analytical tests. Although not necessary for diagnosis, they help to rule out other autoimmune diseases.
