was bedeutet crp beim blutbild — what symptoms are typical?

CRP (C-reactive protein) is an acute-phase protein produced by the liver in response to inflammation. Elevated CRP in a blood test indicates that inflammation or tissue damage is present somewhere in the body, but it is not specific to any one disease. Typical symptoms that may accompany high CRP are those of the underlying condition: fever, fatigue, muscle aches, swelling, redness, or loss of function in affected areas. In infections, symptoms like cough, diarrhea, or localized pain often appear. In chronic inflammatory diseases (e.g., rheumatoid arthritis, atherosclerosis), CRP may be mildly elevated without obvious acute symptoms. Importantly, CRP alone cannot diagnose a disease – it is a non-specific marker. A normal CRP does not rule out inflammation, and an elevated level requires further investigation. The symptoms are those of the underlying cause, not of CRP itself. For consumer health tests, CRP should always be interpreted together with other lab values and clinical evaluation by a physician.
