How to read cholesterol blood test results

Understanding cholesterol levels can be confusing, but it is an important part of your health. When it comes to understanding the difference between lipids, "good cholesterol," "bad cholesterol" and triglycerides, you often need expert advice. Learn what each term means and what the American Heart Association's guidelines are for healthy levels of each.

Lipids

Fats, cholesterol and other waxy substances fall under the classification of lipids. The lipids that cause particular concern are triglycerides.

Triglycerides

Triglycerides are fats that, along with cholesterol, are thought to be a major factor in the development of coronary artery disease. The American Heart Association (AHA) recommends a level of less than 150 mg/dL.

HDL

High-density lipoprotein (HDL) is known as "good cholesterol" and is thought to help remove build-up in the coronary arteries. According to the American Heart Association, HDL makes up one-forth to one-third of the total cholesterol levels.

LDL

Low-density lipoprotein (LDL), better known as "bad cholesterol" or just "cholesterol," sticks to the walls of the artery, causing build up and contributing to coronary artery disease. The American Heart Association recommends a level of less than 100 mg/dL.

Total Cholesterol

Total cholesterol is the total of both HDL and LDL levels. The American Heart Association recommends a total cholesterol level of less than 200 mg/dL.
