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

The storage duration of a stool sample depends on its intended use. For DNA analysis (e.g., microbiome testing), the sample should ideally be frozen at -20 °C or -80 °C within a few hours of collection. At room temperature or refrigerated (4 °C), DNA remains stable for only 24–48 hours; after that, microbial growth and DNA degradation occur. A DNA test can help analyze microbial composition or detect pathogens, but only if the sample has been stored properly. The provided context does not include specific information on stool storage or DNA testing for stool samples. Therefore, the evidence is unclear. Consumers should follow the instructions of their specific test kit. Improper storage can compromise results.
