Non-HDL Cholesterol Calculator

How to calculate Non-HDL cholesterol?

Non-HDL cholesterol represents all the "bad" cholesterol types in your bloodstream. Unlike LDL alone, it accounts for every lipoprotein that can contribute to arterial plaque buildup and cardiovascular disease.

Formula: Non-HDL = Total Cholesterol - HDL

Using the calculator: a practical example

To understand how this works, let's look at a common scenario where an individual has a Total Cholesterol reading of 200 mg/dL and an HDL (good) cholesterol level of 50 mg/dL.

Step-by-step calculation

• First, subtract the HDL value (50) from the Total Cholesterol (200).
• Check the resulting Non-HDL value, which is 150 mg/dL in this example.
• Finally, calculate the Total/HDL ratio by dividing 200 by 50 to get a ratio of 4.0.

Frequently Asked Questions

Why is Non-HDL important?
It captures all atherogenic particles (including LDL, VLDL, and IDL) that contribute to heart disease, providing a more comprehensive risk profile than looking at LDL alone.

What is a good Non-HDL level?
For most healthy adults, a Non-HDL level is generally considered good if it is below 130 mg/dL. However, targets may be lower depending on individual heart disease risk factors.

How does it differ from LDL?
While LDL measures one specific type of "bad" cholesterol, Non-HDL includes LDL plus other triglyceride-rich lipoproteins like VLDL and IDL that also damage arteries.
