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

CRP (C-reactive protein) is a blood biomarker for inflammation, measured via a blood test, not a DNA test. A DNA test can identify genetic variants in genes like CRP, IL6, or TNF-α that are associated with slightly higher or lower CRP levels. However, these genetic effects are small (typically 0.1–0.5 mg/L) and are overshadowed by lifestyle, diet, infections, and chronic diseases. Therefore, a DNA test cannot replace a direct CRP blood measurement. Evidence comes from GWAS (e.g., PMID: 20383146) showing moderate associations but no clinical predictive power for individuals. For assessing inflammation risk or status, a blood test remains the gold standard. A DNA test may provide complementary insight but should not be used for diagnosis or treatment decisions. Caution: a normal CRP does not rule out chronic inflammation, and an elevated level requires medical evaluation.
