8.0 Investigations

Investigations are unnecessary in most cases of alopecia areata. When the diagnosis is in doubt appropriate tests may include fungal culture, skin biopsy, serology for lupus erythematosus or serology for syphilis. The increased frequency of autoimmune disease in patients with alopecia areata is probably insufficient to justify routine screening.

One small case series suggested that iron deficiency is more common in women with alopecia areata than the population at large[17] but this was not confirmed in two subsequent studies,[18,19] and routine testing for iron status is not recommended. There are no published studies demonstrating a treatment response to iron replacement therapy.
