This test is user-pay.

The average of two assays two weeks apart provides a more stable estimate of the level of this marker.  Levels of CRP >10 mg/L likely indicate active inflammation or the presence of chronic inflammatory condition, which can invalidate the prediction of coronary risk.  In most cases, a period of two weeks is adequate for CRP concentrations to return to basal values.

Higher levels of CRP are associated with increased risk of future cardiovascular events.

<1 mg/L	Decreased risk
1-3 mg/L	Average risk
>3 mg/L	Increased risk
