C-Reactive Protein (CRP) is an acute-phase protein, produced exclusively in the liver. Interleukin-6 is the mediator for the synthesis by the hepatocytesof CRP, a pentamer of approximately 120kDa. CRP is present in the serum of normal persons at concentrations ranging up to 5 µg/ml. High Sensitive (hs)CRP is the novel and evolving biomarker which provides a most useful predictive indicator for subsequent cardiovascular events. A series of prospective studies provide consistent data documenting that mild elevation of baseline levels of CRP among apparently healthy individuals is associated with higher long-term risk for future cardiovascular events. This predictive capacity of CRP is independent of traditional cardiovascular risk factors and offers a prognostic advantage over measurement of lipid alone. Inflammatory markers, specifically hsCRP, may help to identify those who would benefit most from these pharmacological intervention. This test should not be used for assessment of acute inflammation. For acute inflammation normal CRP can be measured (cat.# HK358). This ELISA can for example be used to evaluate Cardiovascular Disease (CVD) risk in apparently healthy individuals who have not had recent infection or other serious illness. CRP values which are <1.0 mg/l="" indicate="" a="" low="" risk="" for="" cvd,="" 1.0-2.9="" mg/l="" an="" intermediate="" risk="" for="" cvd="" and="">3.0 mg/L a high risk for CVD.The standards in this kit have been calibrated against the NIBSC 1st International Standard, 85/506.
