Reference Range
≤17 years: Not established
>17 years: Optimal <1.0 mg/L
hsCRP level (mg/L) Risk According to AHA/CDC Guidelines
<1.0 Lower Relative Cardiovascular Risk
1.0-3.0 Average Relative Cardiovascular Risk
>3.0-10.0 Higher Relative Cardiovascular Risk. Consider retesting in 1 to 2 weeks to exclude a benign transient
elevation on the baseline CRP value secondary to infection or inflammation.
>10.0 Persistent elevations upon retesting, may be associated with infection or inflammation
