Why This Test Matters

Cholesterol is a type of fat that your body needs, but having too much can build up in your arteries, increasing your risk of heart disease or stroke. HDL cholesterol helps remove cholesterol from your arteries. This test helps doctors evaluate your overall cholesterol health and identify areas for improvement.

How the Test Works

Blood is drawn from a vein in your arm. The sample is processed to separate serum, where cholesterol and HDL levels are measured using a specialized immunoassay or enzymatic method. Results are reported as a total cholesterol value and HDL subtype concentration.

What You Should Know Before Testing

You may be asked to fast for 12 hours before the test to get more accurate results. Avoid smoking, caffeine, or heavy meals right before your appointment. Wear comfortable clothing and bring any medications you’re currently taking.

Common Results and Interpretation

Total cholesterol and HDL levels are used together to assess your risk. While specific reference ranges vary by lab, higher total cholesterol or lower HDL levels may signal a need for lifestyle changes or medical advice.

Clinical interpretation
