Lipids, such as cholesterol and triglyceride, are insoluble in plasma. They are made soluble by attachment to circulating lipoproteins that transport lipids to various tissues for energy utilization, lipid deposition, steroid hormone production, and bile acid formation. The lipoprotein consists of esterified and unesterified cholesterol, triglycerides, and phospholipids, and protein. There are five major lipoproteins in blood: chylomicrons, very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). Each of these classes of lipoproteins carries cholesterol and triglyceride to a varying degree, with LDL carrying the majority of cholesterol and VLDL carrying the majority of triglyceride. In general, patient care issues related to screening, diagnosis, and treatment are based on the results of the measurement of serum lipids, which is generally accomplished by obtaining a lipid profile. On occasion, measur
