Cholesterol is an essential body fat needed to produce substances such as hormones and bile. High levels of cholesterol are usually associated with a higher risk of heart disease and narrowed blood vessels. Lipids included in total cholesterol are HDL cholesterol, LDL cholesterol, and triglycerides.
HDL cholesterol is commonly called “good” cholesterol because it can aid in the removal of excess cholesterol in body tissues and help prevent the accumulation of LDL cholesterol in the arteries. Higher levels of HDL cholesterol are desirable.
LDL cholesterol is considered “bad” cholesterol because it can accumulate in the inner walls of your arteries, narrowing them and reducing blood flow. This result is not measured directly, rather it is derived from the total cholesterol, HDL cholesterol, and triglyceride results. Lower levels of LDL cholesterol are desirable.
Triglycerides are fats composed of fatty acids and glycerol. Triglycerides combine with proteins to form particles called lipoproteins that transport fats through the bloodstream. These lipoproteins carry triglycerides from the liver to other parts of the body that need this energy source. Triglycerides then return to the liver where they are removed from the body. The level of triglycerides in your blood can indicate how efficiently your body processes the fat in your diet. Accurate results require a minimum of a twelve-hour fast (no food or drink except water and medication) prior to testing.
This calculation is obtained by dividing the total cholesterol level by the HDL cholesterol level. The higher the number, the greater the risk of coronary heart disease.
