NutriCare | INFINITY DNA-Test: can a microbiome test help?

The NutriCare INFINITY DNA-Test is primarily a genetic test, but it may include microbiome analysis. Whether a microbiome test is helpful requires a nuanced answer. Current scientific evidence indicates that commercial microbiome tests for healthy adults and children lack clinical validation. A low Bifidobacteria level, for example, is not a confirmed disease diagnosis but a single measurement heavily influenced by diet, daily variation, and lab differences. Probiotics have specific indications (e.g., post-antibiotic use), but routine supplementation based solely on a test result is not recommended. Microbiome research is still evolving; many associations are correlational, not causal. A test may provide rough hints but does not replace medical evaluation if symptoms exist. Healthy individuals likely benefit more from a fiber-rich diet than from expensive tests. The evidence level is therefore 'practice' (practice-based, not supported by large RCTs). Caveat: Do not overestimate the predictive power of such tests.
