Overview:
Measurement of CRP by high sensitivity CRP assays may add to the predictive value of other markers used to assess the risk of cardiovascular and peripheral vascular disease.2-8
Increases in CRP values are nonspecific. CRP is an indicator for a wide range of disease processes and should not be interpreted without a complete clinical history. Recent medical events resulting in tissue injury, infections, or inflammation, which may cause elevated CRP levels, should also be considered when interpreting results. Serial analysis of CRP should not be used to monitor the effects of treatment.
