If your doctor suspects that you have atopic dermatitis, he or she may

  • Perform a physical exam and specifically inspect the appearance of the skin
  • Take a personal and family history
  • Perform a skin biopsy (the removal of a small piece of skin for examination) to confirm the diagnosis or to rule out other causes of dry, itchy skin
  • Perform allergy skin testing, which may be helpful for individuals with hard-to-treat atopic dermatitis or who have symptoms of other allergic diseases.
