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

A normal CRP (C-reactive protein) level is generally below 5 mg/L; for high-sensitivity CRP (hs-CRP), <1 mg/L indicates low cardiovascular risk, 1–3 mg/L intermediate, and >3 mg/L high. CRP is a non-specific marker of inflammation – elevations can result from infection, chronic inflammatory conditions, smoking, or obesity. Other relevant blood markers include fibrinogen, interleukin-6 (IL-6), white blood cell count, and erythrocyte sedimentation rate (ESR). Direct-to-consumer tests often report a single CRP value without context, which can be misleading. Evidence for CRP as a standalone predictor is moderate; clinical decisions require repeated measurements and physician evaluation. A normal CRP does not rule out low-grade chronic inflammation.
