was ist ein crp wert im blut — can a DNA test help?

CRP (C-reactive protein) is an acute-phase protein produced in the liver and serves as a non-specific marker of inflammation in the blood. Elevated CRP levels can indicate infection, chronic inflammation, tissue damage, or cardiovascular risk. Measurement requires a standard blood test – a DNA test cannot directly measure CRP. While certain genetic variants (e.g., in the CRP gene) are associated with slightly different baseline CRP levels, the effect sizes are small and not clinically actionable. Direct-to-consumer DNA tests claiming to predict 'inflammation risk' or 'CRP levels' lack evidence. Clinical decisions rely on actual blood CRP measurements, not genetic scores. Therefore, a DNA test cannot help determine your current CRP value or diagnose inflammation. For assessing inflammatory status, a conventional blood test is essential. Evidence: human-moderate (GWAS associations, but no clinical validity for DTC tests).
