THE PROBLEM of what constitutes average, normal, and optimal levels of serum cholesterol and how the results of tests to determine these levels should be applied to clinical practice still bedevils us.

The risk of complications associated with elevated cholesterol levels is increased when other risk factors such as hereditary premature atherosclerosis, hypertension, smoking, and diabetes occur concomitantly. Average levels vary substantially with different ethnic and geographic populations, specific hereditary traits, a number of diseases, and a wide range of dietary habits. This statement is directed to the situation as it exists in the United States today.
