    Test Description


    Total cholesterol is used to measure lipid status and metabolic disorders. Cholesterol is necessary for life, but is also associated with atherosclerosis. It is used to make hormones, vitamin D, and cell membranes. About two-thirds of the body's cholesterol is made by the liver and one-third obtained through the diet. Increased cholesterol is found in high fat diets, primary hypercholesterolemia, the nephritic syndrome, hypothyroidism, primary biliary cirrhosis and in some cases of diabetes. Low levels have been found in malnutrition, malabsorption, severe liver disease, polycythemia vera, etc.
