wie hoch darf der crp wert sein — what are common causes?

CRP (C-reactive protein) is measured in mg/L. For cardiovascular risk: <1 mg/L = low risk, 1–3 mg/L = moderate risk, >3 mg/L = high risk. Values above 10 mg/L typically indicate acute infection or inflammation. Common causes of elevated CRP include infections, chronic inflammatory diseases (e.g., rheumatoid arthritis), smoking, obesity, metabolic syndrome, and tissue injury. Genetic factors like the rs1205 SNP have only a small effect (about 1–3% variance). Lifestyle factors dominate. An hsCRP of 4.2 mg/L is elevated and warrants medical evaluation, especially for cardiovascular risk. Reduction is often achieved through weight loss, exercise, Mediterranean diet, and smoking cessation. Note: Single measurements can fluctuate; repeat testing is recommended.
