wie viel kostet ein blutbild — can a microbiome test help?

The cost of a blood test (Blutbild) varies widely: a basic complete blood count (CBC) costs around €20–30 out-of-pocket, while a comprehensive panel including liver, kidney, lipids, and glucose can range from €50–100. In Germany, statutory health insurance covers these only with a medical indication. A microbiome test (stool test) analyzes gut bacteria composition, not blood markers. It may provide additional insights into digestion, inflammation, or metabolism, but it cannot replace a blood test. Evidence for microbiome tests directly aiding weight loss is weak to mixed; most studies show associations, not causation. For weight management or metabolic health, a standard blood test (fasting glucose, HbA1c, TSH, vitamin D) should be the first step. A microbiome test can be an optional add-on, but its clinical utility is limited due to poor reproducibility and lack of robust intervention data. Be cautious of marketing claims. Evidence: mixed.
