Enter the total cholesterol level and high-density lipoprotein cholesterol level into the calculator to determine the Atherogenic Index. This calculator can also evaluate any of the variables given the others are known.

## Atherogenic Index Formula

The following formula is used to calculate the Atherogenic Index.

AI = (TC - HDL) / HDL

Variables:

• AI is the Atherogenic Index
• TC is the total cholesterol level (mg/dL)
• HDL is the high-density lipoprotein cholesterol level (mg/dL)

To calculate the Atherogenic Index, subtract the high-density lipoprotein cholesterol level from the total cholesterol level. Then, divide the result by the high-density lipoprotein cholesterol level.

## What is an Atherogenic Index?

The Atherogenic Index is a medical tool used to predict the risk of cardiovascular diseases in an individual. It is calculated based on the levels of different types of cholesterol in the body, including total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). A higher Atherogenic Index indicates a higher risk of developing atherosclerosis and subsequent cardiovascular diseases.

## How to Calculate Atherogenic Index?

The following steps outline how to calculate the Atherogenic Index (AI).

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, gather the formula from above = AI = (TC – HDL) / HDL.
4. Finally, calculate the Atherogenic Index.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

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
