Apoliprotein B-100

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

Sample type and Volume required: 
Clotted (yellow SST tube). Serum.
Turnaround time: 
3 days
Special sample instructions: 

Seat the patient 5 minutes before sampling. Fasting sample preferred, but non-fasting acceptable. Patient should follow their normal diet for 3 weeks prior to sampling.
