What role does AllergieCheck | IgE-Antikörper Test play in Haut?

The AllergieCheck (IgE antibody test) measures specific IgE against common allergens. In skin conditions like eczema or urticaria, it can help identify allergic sensitization. However, a positive IgE result does not automatically mean the skin symptoms are caused by that allergen – there is often a gap between sensitization and clinical relevance. The test provides clues but does not replace physician-led diagnostics (e.g., provocation tests). Moreover, many skin disorders are not IgE-mediated. Evidence is moderate: the test is clinically established, but its predictive value for skin complaints is limited. Combining it with history and possibly specific IgG/IgA tests (e.g., for food allergies) can be useful. Caveat: overinterpretation of IgE results may lead to unnecessary diets or avoidance behaviors.
