Answer

History and the physical examination are the most important aspects of diagnosis in patients with androgenetic alopecia. The following laboratory tests, however, can play a role in patient assessment:

  • Dehydroepiandrosterone (DHEA)-sulfate and testosterone analysis: In women, if virilization is evident

  • Iron, total iron-binding capacity, and transferrin saturation: To test for iron deficiency, if telogen effluvium is present

  • Thyrotropin level: If a thyroid disorder is suspected
