AllergieCheck | IgE-Antikörper Test: which blood markers matter?

The IgE antibody test (AllergyCheck) measures total immunoglobulin E (IgE) levels and specific IgE antibodies to common allergens such as pollen, dust mites, pet dander, or foods. It is crucial to understand that elevated IgE or positive specific IgE indicates sensitization – an immune response to an allergen – but does not necessarily mean clinical allergy with symptoms. False positives are common, especially for total IgE. Clinical correlation with symptoms, history, and possibly provocation tests is essential. Key blood markers typically measured: total IgE (age-dependent reference range) and specific IgE to individual allergens (e.g., grass, birch, mites, peanut). Caveat: Antihistamines can affect results; preparation (discontinuation) is recommended. This test is a screening tool, not a standalone diagnosis. In children, caution is warranted as the immune system is still developing.
