Tests and diagnosis

By Mayo Clinic staff

Medical history and exam
If your doctor suspects you have vitiligo, he or she will ask about your medical history and examine you. Important factors in your medical history include:

  • A family history of vitiligo or an autoimmune disease
  • A personal history of sun sensitivity or other skin conditions
  • A rash, sunburn or other skin trauma within two to three months of the start of pigment loss
  • Premature graying of the hair (before age 35)
  • Stress or physical illness

Your doctor will also examine you to rule out other medical problems or skin conditions, such as dermatitis or psoriasis.

Skin biopsy and blood draw
Along with gathering your personal and family medical history and examining your skin, your doctor may also:

  • Take a small sample (biopsy) of your affected skin
  • Draw blood to check your blood cell count, thyroid function and to look for the presence of anti-nuclear antibodies (a type of autoantibody) that would indicate an autoimmune disease

Additionally, your doctor may recommend that you see an eye specialist (ophthalmologist) for an eye examination to check for inflammation in your eye (uveitis).
