Apolipoprotein A1 is a major protein of HDL. Apolipoprotein B is the only protein of LDL. Apolipoprotein concentrations provide sensitive and specific markers for coronary artery disease (CAD). Measurement of Apo A1 and B are useful tools for the assessment of CAD. Apo A1 is a better discriminator of angiographically documented CAD than HDL-cholesterol. When Apo A1 and Apo B results are considered together as a ratio, ApoB/ApoA1 correlated better with the degree of coronary stenosis when compared to total HDL, and LDL-cholesterol, during monitoring of the effects of cholesterol-lowering drugs such as Lovastatin. Low apolipoprotein A-1, high apolipoprotein B and high lipoprotein (a) correlate with increased risk of MI or stroke.

Patient should fast 12 hours prior to testing. Moderately or
grossly lipemic, icteric, or hemolyzed samples are not suitable for
analysis. Split serum into 2 plastic vials.
