Typical costs for microbiome tests in everyday life vary widely depending on scope and provider. Basic stool tests for a rough analysis of gut flora often cost between €50 and €150. More comprehensive tests that also examine bacterial diversity, fungi, and specific pathogens usually range from €200 to €500. Additional costs include supplements (probiotics, prebiotics) and dietary changes based on test results – these can add €30 to €100 or more per month. Importantly, many commercial microbiome tests are not clinically validated and often provide contradictory or exaggerated recommendations. The evidence for the benefit of such tests in daily life is weak; they do not replace medical diagnosis. Consumers should be wary of expensive packages that promise 'personalized' health plans. Actual costs can quickly escalate without proven health benefits.
