Normal Range of High-Sensitivity C-Reactive Protein (hs-CRP)
After undergoing a complete blood count (CBC) test, many people notice “high-sensitivity C-reactive protein” (hs-CRP) listed in their results but are unsure of its meaning. So, what is the normal reference range for hs-CRP?
Normal Reference Range for High-Sensitivity C-Reactive Protein (hs-CRP)
The normal reference range for hs-CRP is 0.5–10 mg/L. Levels of hs-CRP remain relatively stable over time and are unaffected by circadian rhythms or food intake. In healthy individuals, the average plasma concentration of hs-CRP is approximately 1–2 mg/L. However, in cases of systemic, low-grade vascular inflammation—such as that associated with atherosclerosis—the amount of CRP synthesized in the body remains comparatively low, limiting the clinical utility of conventional detection methods.

High-sensitivity C-reactive protein (hs-CRP) is a form of C-reactive protein (CRP) present in plasma. Its primary clinical applications include risk assessment and monitoring in cardiovascular disease, infectious conditions, and renal transplantation. As a nonspecific biomarker of systemic inflammation synthesized by the liver, hs-CRP is one of the strongest independent predictors of cardiovascular risk. Laboratory measurement of hs-CRP employs ultra-sensitive analytical techniques capable of detecting very low concentrations of CRP.

If hs-CRP levels significantly exceed the normal range, comprehensive clinical evaluation is essential, and timely therapeutic intervention should be initiated to prevent disease progression. We recommend incorporating regular, moderate physical exercise into daily routines to enhance overall physical fitness and immune resilience. Additionally, dietary habits should emphasize light, balanced meals. We hope this information proves helpful. Wishing you optimal health and happiness!
