From: Immunoglobulin E-Mediated Allergy Plays a Role in Atopic Eczema as Shown in the Atopy Patch Test
In 53 (17%) of 314 patients of a European multicenter study,[59]positive APT reactions, but negative corresponding skin prick test/specific IgE results, were observed (1 allergen, n = 26; 2 allergens, n = 12). In 22 of these patients with a clear-cut positive APT result, no positive skin prick test or elevated specific serum IgE of the investigated allergen panel was seen (7% of total). The figure shows that all allergens contribute to these reactions.
