Introduction
The normal range for high-sensitivity C-reactive protein (hs-CRP) is 0.5–10 mg/L, and its levels are unaffected by time of day or food intake. In healthy individuals, the average hs-CRP concentration ranges from 1 to 2 mg/L. When inflammation associated with atherosclerosis reflects systemic, low-grade vascular inflammation, the amount of CRP synthesized in the body is relatively low, thereby limiting the utility of conventional detection methods.
After undergoing a complete blood count (CBC) test, many people notice “high-sensitivity C-reactive protein” (hs-CRP) listed in their results. You may be unfamiliar with this term. So, what is the normal reference range for hs-CRP?
Normal Reference Range for High-Sensitivity C-Reactive Protein
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 rhythm 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 relatively low, thereby 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 for cardiovascular disease, evaluation of infection, and monitoring after kidney transplantation. As a nonspecific marker of systemic inflammation synthesized by the liver, hs-CRP is one of the strongest predictive biomarkers for cardiovascular risk. Laboratory measurement of hs-CRP employs ultra-sensitive detection techniques capable of quantifying very low concentrations of CRP.
If your hs-CRP level significantly exceeds the normal reference 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 your daily routine to enhance overall physical fitness and immune resilience. Additionally, maintain a light, balanced diet. We hope this information has been helpful. Wishing you good health and happiness!
