Document Summary

Cholesterol, triglycerides, and lipoproteins are measured to evaluate a person"s risk for developing atheroscleroticdisease, especially if there is a family history of premature heart disease, or to diagnose a speci c lipoprotein abnormality. Cholesterol and triglycerides are transported in the blood by combining with protein molecules to form lipoproteins. The lipoproteins are referred to as low-density lipoproteins (ldl) and high-density lipoproteins (hdl). the risk of cad increases as the ratio of ldl to hdl or the ratio of total cholesterol (ldl. Hdl) to hdl increases. although cholesterol levels remain relatively constant over 24 hours, the blood specimen for the lipid pro leshould be obtained after a 12-hour fast. Cholesterol (normal level, less than 200 mg/dl) is a lipid required for hormone synthesis and cell membrane formation. It is found in large quantities in brain and nerve tissue. Two major sources of cholesterol are diet (animal products) and the liver, where cholesterol is synthesized.
