What tests for vitiligo should be done?

Before starting vitiligo therapy, several tests may be recommended to ensure an accurate diagnosis and appropriate treatment plan:

Physical Examination

A thorough physical examination is typically the first step. Your dermatologist will:

  • Visually examine your skin from head to toe
  • Note the location and pattern of depigmented patches
  • Use a Wood's lamp (UV light) to better visualize the affected areas, especially on fair skin

Blood Tests

While not always necessary, blood tests may be ordered to:

  • Check for other autoimmune conditions
  • Assess overall health
  • Identify potential underlying causes

Common blood tests include:

  • Antinuclear Antibody (ANA) test
  • Complete Blood Count (CBC)
  • Thyroid function tests

Skin Biopsy

In some cases, a skin biopsy may be performed to:

  • Confirm the diagnosis of vitiligo
  • Rule out other skin conditions
  • Examine the presence or absence of melanocytes

Additional Tests

Depending on individual circumstances, your doctor may recommend:

  • An eye exam to check for uveitis, an inflammation sometimes associated with vitiligo
  • Tests to rule out other autoimmune diseases

It's important to note that the specific tests ordered may vary based on your individual case, symptoms, and medical history. Your dermatologist will determine which tests are necessary to develop the most appropriate treatment plan for your vitiligo.
