wieviel stuhl für stuhlprobe — what can you do yourself?

The required stool amount for a stool sample depends on the specific test kit – typically a pea-sized amount (about 1–2 g) or a defined portion from the provided collection tube. What you can do yourself: Read the instructions carefully, collect from different parts of the stool, avoid urine or water contamination, and store the sample cool (do not freeze unless specified). Avoid strongly colored foods (beets, blueberries), alcohol, and certain supplements (e.g., vitamin C, probiotics) for 24–48 hours before collection if recommended by the kit. For DNA tests (microbiome, nutrigenetics), no special diet is needed, but avoid antibiotics for at least 4 weeks prior as they alter bacterial composition. Important: Collection is simple and painless; no bowel cleansing or fasting is required. Evidence is based on practice recommendations from test providers and general lab standards – no strong clinical studies exist. If unsure, contact the test's customer service.
