What is LDL - Cholesterol?
This test is usually done to determine your risk for heart disease. The LDL test is usually done as part of a lipid analysis, which also checks for total cholesterol, HDL, and triglycerides.
LDL carries cholesterol to various tissues throughout the body. Too much LDL, commonly called "bad cholesterol," can lead to cardiovascular disease.
According to the National Heart, Lung, and Blood Institute, the lower your LDL, the lower your risk for heart disease or stroke.
