NutriCheck I Unverträglichkeits-Test: when to see a doctor?

The NutriCheck I Intolerance Test is a home test that claims to indicate food intolerances. When to see a doctor: If you experience persistent or severe symptoms such as abdominal pain, diarrhea, skin rashes, or breathing difficulties, you should always consult a doctor, as these could indicate more serious conditions. The test itself is not a substitute for medical diagnosis. Many such tests rely on IgG antibodies, whose clinical relevance is debated. Evidence for these home tests is weak to unclear. A doctor can provide a reliable diagnosis through history taking, elimination diets, or validated methods (e.g., breath test for lactose intolerance). Additionally, only a physician can assess interactions with medications or existing diseases. If you are uncertain or if the test shows abnormal results, seeing a doctor is advisable to avoid misinterpretation and unnecessary dietary restrictions.
