What is it?
Cholesterol is a waxy and fat-like substance that is produced by the liver. High-density lipoproteins (HDL) or “good cholesterol” is one of the types of cholesterol found in the body.
Why does it matter?
HDL helps to remove "bad" cholesterol from the arteries by taking the excess back to the liver for removal.
What do abnormal results indicate?
Excess cholesterol in the blood has been shown to lead to coronary artery disease.
