welche blutwerte check up — can a microbiome test help?

A standard blood check-up typically includes a complete blood count, fasting glucose, lipid panel (cholesterol, triglycerides), liver and kidney function, electrolytes, vitamin D, iron status, and sometimes thyroid markers. A microbiome test (e.g., stool analysis) can provide complementary insights into gut bacteria composition, inflammation markers like calprotectin, and microbial diversity. However, it does not replace blood work. The evidence for clinical utility of microbiome tests is still emerging – many associations are mechanistic or observational. A test for specific genes (like FUT2) may hint at gut microbiome patterns, but effect sizes are small. Caveat: normal blood values do not guarantee safety from toxicity if you take high-dose supplements, especially fat-soluble vitamins. A microbiome test can be a useful addition but should not be used alone for medical decisions.
