wie viel stuhl für stuhlprobe — what can you do yourself?

For a stool sample for microbiome analysis, you typically need a small amount – about pea-sized or 1–2 grams. Most kits include a collection tube with buffer solution and a spoon or applicator. It's important to avoid contamination with urine or water. Collect the sample directly after a bowel movement on a clean surface (e.g., toilet paper or a collection sheet). Ship the sample as soon as possible (within a few hours) at room temperature or according to kit instructions. Refrigeration is usually not required, but avoid direct sunlight and heat. What you can do yourself: read the instructions carefully, wash hands, work cleanly, and do not store the sample too long. Results are for orientation, not medical diagnosis. Evidence for the benefit of such tests is still limited (evidence: practice).
