Additional Information

Apolipoprotein B is the major protein component of low density lipoprotein (LDL). A significant correlation exists between Apo B and total cholesterol levels, so ApoB can be viewed as a positive risk factor for the development of CHD. Measurement of Apo B and the ratio Apo B/Apo A-1, may provide better predictive power for the assessment of risk for CHD than traditional blood lipid determinations.
