wie hoch darf der crp wert sein — what symptoms are typical?

C-reactive protein (CRP) is a non-specific marker of inflammation. Normal levels are typically below 5 mg/L. For high-sensitivity CRP (hs-CRP) used in cardiovascular risk assessment, values <1 mg/L indicate low risk, 1–3 mg/L moderate risk, and >3 mg/L high risk. Mildly elevated CRP (5–10 mg/L) can result from infections, smoking, obesity, or stress. Markedly elevated levels (>10 mg/L) suggest acute inflammation due to bacterial infection, autoimmune disease, or tissue damage. Typical symptoms associated with elevated CRP are not caused by CRP itself but by the underlying inflammation: fever, fatigue, body aches, swollen lymph nodes, loss of appetite, and local swelling or redness. Chronic low-grade elevation may present with vague symptoms like tiredness, brain fog, or joint pain. Importantly, a single CRP value cannot diagnose a condition; it must be interpreted alongside clinical history, physical exam, and other lab tests. The evidence linking CRP to inflammation is strong (human-strong).
