Overview:

CRP is an acute phase inflammatory plasma protein synthesized by the liver. The “high sensitivity” CRP test is needed to detect very low levels of CRP that may be seen with vascular and/or systemic inflammation.

Methodology

Immunoturbidimetric

 

  • hs-CRP may be an independent predictor of developing CVD events and can provide independent prognostic information after initiating treatment.
  • High levels of hs-CRP can also predict cardiovascular events and may be useful in determining how well a patient is responding to lifestyle change and statin treatment.1
