wie stuhlprobe aufbewahren — what are common causes?

Stool sample storage depends on the test type. For home kits (e.g., microbiome, fecal occult blood), a collection tube with preservative is usually provided – add sample immediately, seal tightly, store at room temperature or refrigerate per instructions, and return within 24–48 h. Without preservative, refrigerate (2–8 °C) and process within hours. Freezing is only recommended for specific tests (e.g., stool culture). Common reasons for stool collection include: colorectal cancer screening (iFOBT), infection detection (bacteria, parasites), microbiome analysis, inflammation markers (calprotectin), or suspected malabsorption. Avoid contamination with urine or water; do not sample from toilet water. Improper storage reduces test accuracy. Always follow the specific kit instructions.
