HDL – cholesterol

About the test

HDL cholesterol removes LDL from the vascular walls and transports it to the liver. It is then excreted by bile.

HDL cholesterol is therefore useful in the human body and people with high HDL  are reported to have a decreased risk of cardiovascular disease. This is why it is also known as “good” cholesterol.
