What Is HDL Cholesterol?
Reviewed: Dr. Gromatzky
2. Investigation
Since the costs of directly measuring low density lipoprotein (LDL) and HDL are high, testing is often done for the surrogate value. This means testing is done for the cholesterol associated with the Apo-A1 particles. In normal individuals, about 30% of cholesterol is carried by HDL.
This can be compared with the cholesterol carried by LDL. HDL functions to remove fats and cholesterol and transports it to the liver for reutilization or excretion. This also means that those with higher levels of HDL cholesterol will have fewer cardiovascular issues while those with a lower HDL level with have a higher rate for cardiovascular disease.
