wie lange kann man eine stuhlprobe aufbewahren — can a DNA test help?

The storage duration of a stool sample depends on the test kit and conditions. For a microbiome test (e.g., MyBody-X's gut test), it is generally recommended to refrigerate the sample (2–8 °C) immediately after collection and send it within 24–48 hours. Longer storage, even chilled, can degrade bacterial DNA and compromise results. A DNA test (e.g., a nutrigenetic test) cannot help determine or extend stool sample stability; it analyzes your inherited variants, not the sample's condition. A microbiome test, however, analyzes bacterial DNA from the stool – proper storage is critical. The provided context lacks specific storage instructions; this answer is based on standard lab practice. Caution: Do not use old or improperly stored samples, as they yield unreliable results. If in doubt, contact the test provider directly.
