Skin biopsy: immunofluorescent staining - linear deposits of IgA. 2. Serology test: positive antiendomysium antibody test. As a compromise: the positive serology and the typical skin symptoms are enough for a clinical diagnosis. However, I think most of the dermatologist consider the biopsy as "gold standard" for the diagnosis. It seems that dermatologist needs some education regarding the DH diagnosis ("gluten-sensitive dermatopathy"; this is only my terminology) Karoly Horvath
