Lipid Testing

lipid testing

Lipid testing is a blood test that measures fats and fat-carrying particles in your bloodstream, most commonly cholesterol and triglycerides. Typical results report levels of LDL (often called "bad" cholesterol), HDL (the "good" cholesterol), total cholesterol, and triglycerides; some tests also report or estimate particle numbers and related markers. These measurements help doctors assess your risk of developing artery disease and guide decisions about lifestyle changes or medications. Testing can be done on a fasting or non-fasting blood sample depending on the test and medical advice, and special tests can look at particle types or proteins for a more detailed view. Results are used to track progress over time—showing whether diet, exercise, or medications are working. People with a family history of heart disease, diabetes, high blood pressure, or other risk factors are often advised to have testing, and general screening guidelines suggest periodic checks for adults. Understanding your lipid numbers helps you and your clinician make choices to lower risk, such as improving diet, increasing activity, quitting smoking, or starting cholesterol-lowering drugs. Because abnormal lipid levels are a major and modifiable cause of artery disease, testing provides practical information that can prevent heart attacks, strokes, and other circulation-related problems when followed by appropriate action.
