What can the Stuhlprobe tell you — and what not?

A stool sample test (gut microbiome test) can reveal the composition of your gut bacteria, diversity, and ratios of different bacterial strains. It may indicate potential dysbiosis (imbalance) and is often linked to digestion, immune function, and general well-being. Some tests also screen for pathogenic microbes or inflammatory markers like calprotectin. What it cannot do: A stool test is not a medical diagnostic tool. It does not replace clinical evaluation for serious conditions such as inflammatory bowel disease (IBD), celiac disease, or colorectal cancer. Interpreting results is challenging because a healthy microbiome is highly individual, and there are no standardized 'normal' values. Many commercial tests rely on limited reference databases and overstate clinical significance. Bottom line: The stool test can serve as a lifestyle tracker to monitor dietary changes. It is not suitable for medical decisions. If you have persistent symptoms, consult a doctor.
