was ist ein hoher crp wert — what does this mean exactly?

A high CRP (C-reactive protein) level is a non-specific marker of inflammation. It indicates an ongoing acute or chronic inflammatory response in the body – caused by infection, tissue damage, autoimmune disease, or lifestyle factors such as smoking, obesity, or intense physical exertion. The magnitude of the elevation provides clues about the intensity of inflammation but not its cause. Values above 10 mg/L typically suggest acute infection, while mildly elevated levels (2–10 mg/L) are often linked to chronic low-grade inflammation and increased cardiovascular risk. Importantly, a single high CRP reading is not diagnostic; it must be interpreted in clinical context. From a precision medicine perspective, genetic variants (e.g., in the CRP gene) can influence baseline CRP levels, but their effect sizes are small and not clinically actionable for individual risk assessment. Consumer DNA tests claiming to show an 'increased inflammation risk' should be viewed skeptically – they do not provide a diagnosis. The evidence for CRP as a risk marker is strong (prospective cohorts, meta-analyses), but applicability to individuals is limited. Persistently elevated CRP warrants medical evaluation to identify the underlying cause.
