How are AllergieCheck | IgE-Antikörper Test and fatigue related?

The AllergieCheck (IgE antibody test) from MyBody-X measures specific IgE antibodies to allergens. This indicates sensitization, not clinical allergy. Fatigue can be a symptom of allergies, such as allergic rhinitis or food allergies triggering inflammatory responses. However, the test alone cannot explain or diagnose fatigue. There are no validated studies directly linking the test result to fatigue. The evidence is weak and based on marketing claims, not clinical practice. False reassurance from a negative result may delay proper diagnosis of true allergies or other fatigue causes (e.g., sleep disorders, nutrient deficiencies, chronic inflammation). The test should not be used as the sole basis for health decisions. For persistent fatigue, a medical evaluation with history, physical exam, and possibly further tests (e.g., provocation tests) is necessary.
