Why HDL & LDL Don't Equal Your Total Cholesterol

Your TC, or total cholesterol, is composed of many factors, each of which has value in determining your cholesterol reading. HDL, LDL, triglycerides and VLDL are all factors in your overall cholesterol health.

HDL

• HDL, or high-density lipoprotein, is considered the "good cholesterol." It transports cholesterol away from tissues and to your liver for disposal.

LDL

• LDL, or low-density lipoprotein, is the "bad cholesterol." It transports cholesterol to your arteries and tissues for deposit.

Triglycerides

• Triglycerides are also a part of your cholesterol reading. They are a storage form of fat in your blood used for energy. High levels of triglycerides put you at risk for heart disease.

VLDL

• VLDL is very low-density lipoprotein. It is a type of LDL made by the liver that contains a high proportion of triglycerides. The same methods for lowering your LDL and triglycerides work to lower your VLDL, so many doctors do not mention this number.

Calculations

• To determine your LDL, subtract your HDL from your TC to equal your first number. Divide your triglycerides by 5, and then subtract that number from your first number. VLDL is calculated as one-fifth of your triglycerides level.
