Enter the total cholesterol level and high-density lipoprotein cholesterol level, as well as the triglycerides level into the calculator to determine the Cholesterol Index.

## Cholesterol Index Formula

The following formula is used to calculate the Cholesterol Index.

CI = (TC / HDL) + (TG / 5)

Variables:

• CI is the Cholesterol Index
• TC is the total cholesterol level (mg/dL)
• HDL is the high-density lipoprotein cholesterol level (mg/dL)
• TG is the triglycerides level (mg/dL)

To calculate the Cholesterol Index, divide the total cholesterol level by the high-density lipoprotein cholesterol level. Then, divide the triglycerides level by 5. Add the two results together to get the Cholesterol Index.

## What is a Cholesterol Index?

A Cholesterol Index, also known as a cholesterol ratio, is a calculation used by medical professionals to determine a person’s risk of developing heart disease. It is calculated by dividing the total cholesterol level by the high-density lipoprotein (HDL, or “good” cholesterol) level. A lower ratio indicates a lower risk of heart disease, as it means there is a higher proportion of good cholesterol in the body, which helps to remove low-density lipoprotein (LDL, or “bad” cholesterol) from the bloodstream.

## How to Calculate Cholesterol Index?

The following steps outline how to calculate the Cholesterol Index (CI).

1. First, determine the total cholesterol level (TC) in mg/dL.
2. Next, determine the high-density lipoprotein cholesterol level (HDL) in mg/dL.
3. Next, determine the triglycerides level (TG) in mg/dL.
4. Next, use the formula CI = (TC / HDL) + (TG / 5) to calculate the Cholesterol Index.
5. Finally, calculate the Cholesterol Index using the obtained values for TC, HDL, and TG.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Total cholesterol level (TC) = 200 mg/dL

High-density lipoprotein cholesterol level (HDL) = 50 mg/dL

Triglycerides level (TG) = 150 mg/dL
