What should I know about wie unvertraglichkeiten testen?

When it comes to testing for intolerances, caution is warranted. Many commercial tests (e.g., DNA tests for lactose intolerance, IgG food sensitivity panels) are marketed heavily but often lack strong or reliable evidence. A DNA test for lactase persistence (rs4988235) indicates genetic likelihood, not actual tolerance – genotype does not always equal phenotype. For a reliable diagnosis, clinical methods like a hydrogen breath test or a supervised elimination diet are recommended. IgG-based food intolerance tests are not endorsed by major medical societies because they frequently yield false positives and may lead to unnecessary dietary restrictions. Other tests, such as hormone or metabolic panels (e.g., GPX1 variants), offer only mechanistic clues without strong clinical utility. Bottom line: do not rely solely on genetic or direct-to-consumer tests. Always consult a healthcare professional before making dietary changes. The evidence is mixed – spanning from genetic associations to clinical practice.
