You can't see high cholesterol. You can't feel it. It doesn't have any symptoms. Yet it kills 500,000 Americans each year. It's a major risk factor for coronary heart disease and stroke.

This test is based on the treatment goals of the National Cholesterol Education Program and should be used as a guideline only.
