wann ist der crp wert erhöht — when to see a doctor?

CRP (C-reactive protein) is a non-specific marker of inflammation. Levels above 5 mg/L are generally considered elevated, though reference ranges vary by lab. High-sensitivity CRP (hs-CRP) is used for cardiovascular risk assessment: <1 mg/L low risk, 1–3 mg/L moderate, >3 mg/L high risk. You should see a doctor if CRP is persistently elevated without an obvious cause (e.g., infection, injury), if levels exceed 10 mg/L (suggesting acute inflammation), or if you have accompanying symptoms like fever, fatigue, or joint pain. For cardiovascular risk, an elevated hs-CRP warrants medical evaluation. Important: CRP alone is not diagnostic – it must be interpreted in clinical context. Evidence for routine CRP screening in asymptomatic individuals is moderate; guidelines do not recommend it universally.
