KombiCheck | Unverträglichkeits- & Allergietest: which diet helps?

The KombiCheck (Intolerance & Allergy Test) is a commercial product that often measures IgG antibodies to foods. However, the evidence is critical: IgG tests are considered unsuitable for diagnosing food intolerances or allergies by professional societies (e.g., DGAKI, EAACI). True allergies (IgE-mediated) require medical evaluation with skin prick tests or oral challenges. For intolerances (e.g., lactose, fructose, histamine), targeted elimination diets based on confirmed malabsorption tests are effective. The KombiCheck frequently produces long lists of alleged 'intolerances,' which may lead to unnecessary dietary restrictions. A sensible diet for genuine intolerances is individual: e.g., low-lactose for lactose intolerance, low-FODMAP for IBS, low-histamine for histamine intolerance. Without medical confirmation, radical diets should be avoided. The test is intended as a screening aid, not a diagnosis. Safety note: Always consult a doctor if you suspect an allergy or intolerance.
