Cholesterol Ratio

Cholesterol ratios commonly included in lipid profile tests include the total cholesterol to HDL cholesterol ratio, low density lipoprotein/high density lipoprotein, and high density lipoprotein/low density lipoprotein. The medical community is divided on the effectiveness of using a cholesterol ratio to predict the chances of developing heart disease. For most people, the goal is to keep the total cholesterol to HDL cholesterol ratio below 5:1.

 

Cholesterol Ratio: An Overview

When a person receives his or her cholesterol test (lipid panel) results, several numbers may be listed, including:
 
 
In addition to these numbers, the results from the cholesterol blood test may also show a cholesterol ratio (or several). These cholesterol ratios may include:
 
  • Total/HDL ratio
  • LDL/HDL ratio
  • HDL/LDL ratio.
 

Total Cholesterol/HDL Cholesterol Ratio

One cholesterol ratio is called the total cholesterol to HDL cholesterol ratio, or total/HDL ratio for short.
 This ratio is determined by dividing the HDL cholesterol into the total cholesterol. If a person has a total cholesterol of 200 mg/dL and an HDL cholesterol of 40 mg/dL, the total/HDL cholesterol ratio is 5:1. The goal is to keep this cholesterol ratio below 5:1, with the ideal being below 3.5:1.
 
Cholesterol research scientists and doctors are divided on the effectiveness of this cholesterol ratio for predicting the chances of developing heart disease. At this point, the American Heart Association recommends using the absolute numbers for total blood cholesterol and HDL cholesterol instead of this total/HDL cholesterol ratio. They believe that the absolute cholesterol numbers are more useful to plan treatment than this cholesterol ratio.
