Low Density Lipoproteins (LDL) transport one half to two thirds of all blood cholesterol to various body tissues. This test is a component of the Heart Health Profile. A certain amount of LDL cholesterol (up to 130) is normal. But when the level increases, LDL promotes plaque development on the walls of the coronary arteries, slowing the flow of blood and sometimes blocking the artery entirely. Levels of 130-160 are considered borderline high and levels of 160 or higher are definitely abnormal and should be reduced with rigorous diet, other lifestyle changes, and/or with drug therapy.
