Common mistakes around Stuhlprobe Männer

Common mistakes men make when collecting stool samples for home tests (e.g., microbiome, calprotectin) include several practical errors. The most frequent is urine contamination – men often urinate before or during collection, and urine can alter bacterial composition or inflammatory markers. Second, insufficient sample volume: most kits require a pea-sized amount, but men sometimes provide too little. Third, improper storage: the sample must be refrigerated (2–8 °C) immediately and sent within 24 h; leaving it at room temperature degrades DNA and biomarkers. Fourth, ignoring pre-test restrictions: certain foods (beetroot, broccoli) and medications (PPIs, antibiotics) can skew results. Fifth, timing: for microbiome analysis, the first morning stool is recommended. Sixth, collection method: avoid scooping from toilet water; use a collection hat or plastic wrap. These recommendations come from general laboratory guidelines, not from MyBody-X-specific data. For diagnostic purposes, always follow your doctor's instructions. Evidence level: practice (based on standard preanalytical protocols).
