How are IgE Allergietest and Allergie related?

The IgE allergy test (e.g., MyBody-X AllergieCheck) measures specific IgE antibodies against food or inhalant allergens. However, detectable sensitization does not necessarily mean clinical allergy. Many individuals have IgE against certain allergens without developing symptoms (asymptomatic sensitization). Conversely, allergies can occur without measurable IgE (e.g., non-IgE-mediated reactions). The test is a lifestyle product for adults and is not diagnostic. A medical allergy diagnosis requires additional history, provocation tests, and possibly skin tests. The test can provide orientation but does not replace clinical evaluation. Misinterpretation can lead to false reassurance or unnecessary worry. For children or suspected severe allergies, always consult a physician.
