Laboratory Studies

Laboratory testing, including IgE levels, is not necessary or recommended in the evaluation of suspected atopic dermatitis.



Pathologic findings of biopsy samples include spongiosis with a severely damaged stratum corneum, with hyperproliferation in advanced cases.

Histological studies show an inflammatory infiltrate consisting of memory predominantly CD4 T lymphocytes. Chronic lesions also display increased mast cells, eosinophils, and IgE-bearing Langerhans cells.
