KombiCheck | Unverträglichkeits- & Allergietest: when to see a doctor?

The KombiCheck (Intolerance & Allergy Test) is a home test that often measures IgG antibodies against foods. Scientific evidence for such tests is weak: IgG levels do not reliably indicate true intolerances or allergies. You should see a doctor if you experience recurring symptoms like abdominal pain, diarrhea, skin rashes, or fatigue after eating. An allergist or gastroenterologist can use validated methods (e.g., skin prick test, IgE measurement, supervised elimination diet) for an accurate diagnosis. This home test may offer rough orientation but cannot replace medical evaluation. Caution: unnecessary dietary restrictions based on these tests can lead to malnutrition, especially in children. Seek immediate medical help for severe symptoms like difficulty breathing or swelling.
