| Cholesterol Levels : What is a cholesterol test? A cholesterol test is a blood test that measures the amount of cholesterol and triglycerides (a type of fat) in your blood. Cholesterol is a waxy, fat-like substance that's found in your blood and every cell of your body. Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods. Your liver makes all the cholesterol your body needs and removes excess amounts. Cholesterol is also found in foods from animal sources, such as meat, egg yolks, poultry, and dairy products. Foods high in dietary fat can increase the cholesterol in your blood. If there's too much cholesterol in your blood, your liver can't remove it all. There are two main types of cholesterol: LDL (low-density lipoprotein), or "bad" cholesterol, and HDL (high-density lipoprotein), or "good" cholesterol. Too much LDL cholesterol in your blood increases your risk for coronary artery disease and other heart diseases. High LDL levels can cause the buildup of a sticky substance called plaque in your arteries. This buildup of plaque is known as atherosclerosis. Over time, plaque can narrow your arteries or fully block them. When this happens, parts of your body may not get enough blood: - If the blood flow to your heart is blocked, it can cause a heart attack. - If the blood flow to your brain is blocked, it can cause a stroke. - If the blood flow to your arms or legs is blocked, it can cause peripheral artery disease.
