Also Known As: Cholesterol Test, Direct LDL Cholesterol Test, LDL-C Test, Calculated LDL Cholesterol Test
Cholesterol is a fat-like substance that can be found throughout the body and in the blood. There are different types of cholesterol, and low-density lipoprotein (LDL) cholesterol is sometimes called the “bad” cholesterol because too much of it may clog your arteries with a buildup of plaque.
Testing assesses how much LDL cholesterol is in your blood. This testing helps inform you and your doctor about your risk of heart disease, stroke, diabetes, and other health conditions. Cholesterol testing can also be used to evaluate whether treatment for high cholesterol is working.
