Risks and limits of Mikrobiom Kinder

Analyzing a child's microbiome carries several risks and limitations that are often undercommunicated. First, validated reference ranges for children are lacking – the gut microbiota changes dramatically with age, diet, and environment, so a single test cannot reliably indicate 'health' or 'disease'. Second, many commercial tests make exaggerated claims (e.g., 'personalized nutrition advice') despite weak or absent scientific evidence for such recommendations in children. Third, an abnormal result (e.g., low diversity) can cause unnecessary parental anxiety, leading to unwarranted doctor visits or dietary changes that may harm the child. Fourth, these tests are not regulated as medical devices in the EU; they are classified as lifestyle products without diagnostic approval. Fifth, reproducibility is poor – different labs often report different results for the same sample. For healthy children without specific symptoms, such tests are not recommended. If genuine symptoms exist (e.g., chronic abdominal pain), a pediatrician should be consulted, not a direct-to-consumer test.
