How does C-reactive protein (CRP) differ from high-sensitivity CRP (hs-CRP) in clinical use?

CRP and hs-CRP differ mainly in sensitivity and clinical use. Standard CRP is a general marker of inflammation or infection, rising with acute inflammatory processes but not designed to quantify very low levels. High-sensitivity CRP uses a more precise assay that can detect much lower CRP concentrations, enabling risk stratification for cardiovascular disease in asymptomatic individuals. In practice, CRP helps assess acute inflammation, while hs-CRP informs long-term cardiovascular risk and guides preventive decisions. They are not interchangeable, since the sensitivity and the clinical questions they address differ. Lipid levels and liver function are not measured by these tests, and hs-CRP does have clinically useful applications beyond acute inflammation.
