Vitiligo Diagnosis

The common methods used for vitiligo diagnosis include:

1. Wood's Lamp Examination (UV examination)
2. Skin Biopsy (Cutaneous Biopsy)
3. Blood Tests
4. Autoimmune Antibody Tests
5. Thyroid Antibody Tests
6. Antinuclear Antibody Test (ANA Test)

The accuracy of diagnostic tests for vitiligo varies. Wood's Lamp Examination and Skin Biopsy have high accuracy in confirming the condition. Blood tests, including autoimmune antibody tests and thyroid antibody tests, have moderate to high accuracy in detecting associated conditions. The Antinuclear Antibody Test also has moderate to high accuracy in identifying autoimmune disorders.

Early and accurate diagnosis in vitiligo is important to initiate timely treatment, manage disease progression, and provide psychological support. It allows for better outcomes, improved quality of life, and the opportunity to address associated conditions. Additionally, early intervention can prevent further depigmentation and enhance the effectiveness of therapeutic interventions.
