How are IgE Allergietest and Müdigkeit related?

An IgE allergy test measures specific antibodies to allergens. Fatigue can be a symptom of allergic reactions, e.g., due to histamine release or chronic inflammation. However, fatigue is non-specific and can have many causes (sleep deprivation, stress, infection). The test itself does not indicate fatigue; it only shows sensitization. A positive IgE result does not necessarily mean that fatigue is caused by that allergen. MyBody-X does not appear to offer an IgE allergy test based on the provided context. The evidence for a direct link between IgE test results and fatigue is weak and unsupported by the given sources. Caution: an allergy test cannot replace a medical workup for fatigue.
