How to Figure a Cholesterol Ratio

Blood cholesterol readings are used to assess health and to determine risk of disease. A comprehensive blood cholesterol reading has several components, and one of these is the cholesterol ratio. While this ratio is not used to determine appropriate treatment to reduce high cholesterol, it is sometimes used as a predictor of heart disease risk. The higher your cholesterol ratio, the higher your risk of developing heart disease.

Instructions

• 1

  Determine your total cholesterol reading in mg/dL. If you have recently had your blood cholesterol measured by a health professional, total cholesterol will be provided. It is often abbreviated "TC."

• 2

  Determine your high-density lipoprotein cholesterol in mg/dL. This also called "HDL cholesterol" and is often referred to as "good" cholesterol.

• 3

  Divide your total cholesterol by your HDL cholesterol.

• 4

  Record the ratio you determine through this calculation. This is your cholesterol ratio. For example, if your total cholesterol is 200 mg/dL and your HDL cholesterol is 40 mg/dL, your ratio is 5:1.

• 5

  Aim to keep your ratio below 5:1 for health. An optimum level is 3.5:1.
