Is AllergieCheck | IgE-Antikörper Test useful for Müdigkeit?

The AllergieCheck (IgE antibody test) measures specific IgE against food or inhalant allergens. It is primarily intended for diagnosing allergies such as hay fever or food allergies. Fatigue is a very non-specific symptom with many possible causes (sleep deprivation, stress, iron deficiency, thyroid issues, etc.). Without accompanying allergy symptoms (sneezing, itching, rash), the test is generally not useful for evaluating fatigue. Consumer tests often overstate their utility and can lead to false conclusions. A positive IgE result does not necessarily indicate a clinically relevant allergy. The evidence for using this test in fatigue is weak and based on clinical experience rather than robust studies. Persistent fatigue should be medically evaluated before relying on allergy tests.
