was ist ein hoher crp wert — which blood markers matter?

A high CRP (C-reactive protein) level is a non-specific marker of inflammation. Normal values are below 1 mg/L; levels above 3 mg/L suggest low-grade chronic inflammation, and above 10 mg/L indicate acute infection or tissue damage. CRP is produced in the liver, mainly in response to interleukin-6 (IL-6). An elevated CRP alone is not diagnostic – it must be interpreted in clinical context. Important complementary blood markers include: IL-6, fibrinogen, TNF-alpha, erythrocyte sedimentation rate (ESR), and high-sensitivity CRP (hs-CRP) for cardiovascular risk assessment. Genetic factors play a role: variants in the IL6 gene (e.g., rs1800795) or CRP polymorphisms (see meta-analysis on stroke risk, PMID 37221147) have only small effects. Clinical relevance is limited because lifestyle, infections, and chronic diseases influence CRP levels more strongly. A single elevated reading should be repeated and correlated with other parameters. Caveat: Without medical evaluation, no specific disease can be inferred. Evidence for CRP as a risk marker is strong, but the genetic component is moderate.
