Introduction Lipids are the building blocks of the fats and fatty substances found in animals and plants. They are microscopic layered spheres of oil, which, in animals, are composed mainly of cholesterol, triglycerides, proteins (called lipoproteins), and phospholipids (molecules made up of phosphoric acid, fatty acids, and nitrogen). Lipids do not dissolve in water and are stored in the body to serve as sources of energy. Cholesterol Cholesterol is present in all animal cells and in animal-based foods (not in plants). In spite of its bad press, cholesterol is an essential nutrient necessary for many functions, including: Repairing cell membranes Manufacturing vitamin D in the skin Producing hormones, such as estrogen and testosterone Possibly helping cell connections in the brain that are important for learning and memory Regardless of these benefits, when cholesterol levels rise in the blood, they can have dangerous consequences, depending on the type of cholesterol.

Alternative Names High-density lipoprotein test What the risks are There is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.

The combined information gathered from all of these tests may help your risk of heart attack, stroke, and peripheral vascular disease. Your health care provider may recommend therapy if your risk is found to be high. Regular exercise can increase HDL levels by several points.
