was ist der crp-wert — when to see a doctor?

CRP (C-reactive protein) is a non-specific marker of inflammation produced by the liver. Normal levels are below 5 mg/L; for high-sensitivity CRP (hsCRP), <1 mg/L indicates low, 1–3 mg/L intermediate, and >3 mg/L high cardiovascular risk. An elevated CRP alone does not distinguish between infection, chronic inflammation, or tissue damage. When to see a doctor? If CRP is >10 mg/L with fever, pain, or unexplained fatigue – this may indicate an acute infection. For persistently elevated hsCRP (>3 mg/L) without obvious cause (e.g., after intense exercise), a physician should evaluate cardiovascular risk factors. CRP is also used to monitor chronic conditions like rheumatoid arthritis or inflammatory bowel disease. Important: A single high value is not a reason to panic – it must be interpreted alongside symptoms, lifestyle, and other labs. In athletes, hsCRP can transiently rise after training; repeat testing after rest is advised. Evidence for CRP as a risk marker is strong (human-strong), but the test is non-specific. Do not self-medicate with anti-inflammatories without medical guidance.
