wie lange kann man eine stuhlprobe aufbewahren — when to see a doctor?

The storage time for a stool sample depends on the intended test. For microbiological culture (e.g., for pathogens), the sample should reach the lab within 2–4 hours to maintain viability. For fecal occult blood tests or calprotectin, refrigeration at 2–8 °C is acceptable for up to 24–48 hours, but always follow the specific kit instructions. For gut microbiome analysis (e.g., MyBody-X), specialized preservation tubes allow storage at room temperature for several days. When to see a doctor: persistent diarrhea, blood in stool, unexplained weight loss, severe abdominal pain, or fever. Also seek medical advice if home test results are repeatedly abnormal.
