Is AllergieCheck | IgE-Antikörper Test useful for Stress?

The AllergieCheck (IgE antibody test) is not useful for assessing stress. IgE antibodies are specific to allergic reactions against environmental allergens such as pollen, pet dander, or foods. Stress, in contrast, is a complex psychophysiological state mediated by hormones like cortisol, adrenaline, and noradrenaline. There is no scientifically established link between IgE levels and acute or chronic stress. Some companies misleadingly market such tests as a 'stress check,' but this lacks evidence. The evidence for any benefit in stress is purely marketing-based. If you want to objectively measure stress, validated tools like the Perceived Stress Scale or biomarkers such as salivary or hair cortisol are appropriate. The AllergieCheck could only be indirectly relevant if an undiagnosed allergy itself causes stress-like symptoms – but this is uncommon and requires medical evaluation. In summary, the test is not useful for stress and should not replace proper medical assessment.
