Reference Values

Normal Range: 0.00-3.00 mg/L

 

HS-CRP values for determining risk of developing cardiovascular disease:
HS-CRP Relative Risk
<1.00 mg/L  Low
1.00-3.00 mg/L Average
>3.00 mg/L High


If the HS-CRP level is >10 mg/L, the test should be repeated and the patient examined for sources of inflammation.  Patients with persistent, unexplained elevations of the hs-CRP >10 mg/L should be evaluated for non-cardiovascular etiologies.
