KombiCheck | Unverträglichkeits- & Allergietest: what symptoms are typical?

The 'KombiCheck' (Intolerance & Allergy Test) is a home test that measures IgG antibodies to foods. Typical symptoms often linked to intolerances or allergies include bloating, diarrhea, abdominal pain, fatigue, skin rashes, headaches, and brain fog. However, the clinical evidence for IgG-based food sensitivity tests is weak. True allergies (IgE-mediated) can cause severe, life-threatening reactions like anaphylaxis. This test may provide clues but is not a substitute for medical diagnosis. Many symptoms overlap with other conditions (e.g., IBS, stress). Results should be discussed with a doctor or dietitian before making major dietary changes.
