Cholesterol Tests

Doctors draw a small amount of blood, then analyze it in a lab, to determine your cholesterol level.

A cholesterol test is a simple blood test that's nearly painless and fairly inexpensive. And getting your blood-cholesterol level checked is the first step in keeping it under control.

In a doctor's office or at a hospital, a small amount of blood is drawn into a test tube and analyzed at a laboratory. The test result is then sent back to your doctor, who informs you of the numerical value and explains what it means. The numerical value indicates the weight, in milligrams, of the cholesterol contained in one deciliter of your blood and is expressed as mg/dL.

New technology has also made large-scale cholesterol screening possible. Cholesterol screening programs use portable machines that deliver results in less than ten minutes, using blood drawn by pricking the patient's finger.

The programs offer many Americans the convenience of having their cholesterol checked in such places as shopping malls and workplaces, but the results of such tests should be confirmed at a doctor's office or a laboratory, where greater accuracy can be achieved.

A lipid panel gives doctors more information about your cholesterol level. Find out about this test on the next page.
