APO-B | Apolipoproteins Blood Test

Apolipoprotein B (APO B) is the primary apolipoprotein of low density lipoproteins (LDL or "bad cholesterol"), which is responsible for carrying cholesterol to tissues. While it is unclear exactly what functional role APO B plays in LDL, it is the primary apolipoprotein component and is absolutely required for its formation. What is clear is that the APO B on the LDL particle acts as a ligand for LDL receptors in various cells throughout the body (i.e. less formally, APO B "unlocks" the doors to cells and thereby delivers cholesterol to them). Through a mechanism that is not fully understood, high levels of APO B can lead to plaques that cause heart disease (atherosclerosis). There is considerable evidence that levels of APO B are a better indicator of heart disease risk than total cholesterol or LDL. However, primarily for practical reasons, cholesterol, and more specifically, LDL-cholesterol, remains the primary lipid target and risk factor for atherosclerosis. Apo B-100 levels may be ordered to monitor the effectiveness of lipid treatment.

This is a simple blood test. You must first fast 12 hours before going into lab. The American Heart Ass. established that APO B100 levels that are associated with coronary heart disease, are even a better predictor of it than is LDL level. Abnormal should be followed up by your primary MD.
