Apoliprotein B-100
Description:
Serum Apo A-1 and Apo B concentrations are recognised as better indicators of atherosclerotic risk than cholesterol and triglycerides alone. Atherosclerotic patients are better distinguished from normal individuals by the finding of increased plasma Apo B or decreased plasma Apo A-1 than by a raised LDL and low HDL. The ratio of the Apo A-1 to Apo B may provide a better index of cardiovascular risk than the individual values.
Clinical details:
Apo B is central to lipoprotein transport and is essential for the secretion of Triglyceride (TG) rich lipoproteins from the liver and gut.
Reference range:
Hypobetalipoproteinaemia occurs at ApoB < 0.4 g/L Cardiovascular Risk increases with ApoB > 0.8 g/L
Units:
g/L
