Clinical Significance
Cholesterol is present in tissues and in serum and plasma either as cholesterol or as cholesterol esters bound to proteins. Cholesterol is an essential structural component of cell membranes and the outer layer of plasma lipoproteins and is the precursor of all steroid hormones, including sex and adrenal hormones, bile acids, and vitamin D.
Cholesterol measurements are used to evaluate the risk of developing coronary artery occlusion, atherosclerosis, myocardial infarction, and cerebrovascular disease. Coronary atherosclerosis correlates with a high cholesterol level. Cholesterol concentrations are increased in primary hypercholesterolemia; secondary hyperlipoproteinemia, including nephrotic syndrome; primary biliary cirrhosis; hypothyroidism; and in some cases diabetes mellitus. Low cholesterol concentrations may be found in malnutrition, malabsorption, advanced malignancy, and hyperthyroidism. Serum cholesterol concentration depends on many factors, including age, gender, and diet.
High Density Lipoprotein (HDL) cholesterol is used to evaluate the risk of developing coronary heart disease (CHD). The risk of CHD increases with lower HDL cholesterol concentrations.
