wie viel stuhl für stuhlprobe — can a microbiome test help?

The amount of stool required varies by test kit, but typically a pea-sized sample (about 1–2 grams) is sufficient. Always follow the specific instructions provided with the kit. A microbiome test can help by revealing the composition and diversity of your gut bacteria, which may offer insights into your overall gut health. However, it cannot diagnose medical conditions such as irritable bowel syndrome (IBS) or leaky gut. Those require clinical evaluation by a physician. The evidence for diagnostic claims from such tests is weak; they are marketed as wellness tools, not medical devices. In Germany, direct-to-consumer tests are not cleared for diagnosis. If you have persistent digestive issues, consult a doctor. The test can be a useful starting point for lifestyle adjustments, but it is not a substitute for professional medical advice.
