Lipoprotein Fractionation Ultracentrifugation - This panel measures serum concentrations of total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol and provides a calculated concentration of very low-density lipoprotein (VLDL) cholesterol. Comprehensive lipid assessment aids in evaluating cardiovascular disease (CVD) risk and the likelihood of an ischemic event. It is also useful for the prevention and management of atherosclerotic disease and diagnosis of metabolic syndrome.
