What is non-HDL cholesterol?

Non-HDL cholesterol equals total cholesterol minus HDL cholesterol. It includes all cholesterol carried by atherogenic particles: LDL, VLDL, IDL, and Lp(a). It is a better predictor of atherosclerosis risk than LDL alone.

What is a healthy non-HDL cholesterol level?

For most adults, below 130 mg/dL is considered optimal. For people at high cardiovascular risk (diabetes, prior heart disease, very high LDL), below 100 mg/dL is the ACC/AHA target. Borderline high is 130–159 mg/dL; high is 160–189 mg/dL; very high is 190 mg/dL or above.

Why use non-HDL instead of LDL?

Non-HDL cholesterol does not require a fasting blood draw and is more reliable in people with high triglycerides (above 400 mg/dL), where the standard Friedewald LDL formula becomes inaccurate. It captures all atherogenic particles, not just LDL.

How does non-HDL relate to my LDL goal?

The ACC/AHA recommends that your non-HDL target should be 30 mg/dL higher than your LDL target. For example, if your LDL goal is 70 mg/dL, your non-HDL goal is 100 mg/dL.

Can I calculate non-HDL if I only have my LDL?

Not directly, because non-HDL = Total Cholesterol − HDL, and LDL is only one component. You need both total cholesterol and HDL from a lipid panel report.

Non-HDL cholesterol captures all atherogenic lipoproteins: LDL, VLDL, IDL, and Lp(a). No fasting required.

ACC/AHA Non-HDL Reference Ranges

Category	Non-HDL (mg/dL)	Note
Optimal	< 130	Target for most adults
Borderline High	130 – 159	Lifestyle changes recommended
High	160 – 189	Medical evaluation advised
Very High	≥ 190	High-risk; consult your doctor

For patients with diabetes, prior ASCVD, or LDL ≥ 190 mg/dL, the ACC/AHA target is < 100 mg/dL.

Summary

Non-HDL cholesterol is total cholesterol minus HDL cholesterol. It captures all atherogenic lipoproteins — LDL, VLDL, IDL, and Lp(a) — making it a stronger predictor of cardiovascular risk than LDL alone. The ACC/AHA guidelines set non-HDL targets based on overall cardiovascular risk: below 130 mg/dL is optimal for most adults, and below 100 mg/dL for high-risk patients. This tool calculates your non-HDL value from a standard lipid panel and classifies it against those thresholds.

How it works

Enter your total cholesterol value (mg/dL) from your lipid panel.
Enter your HDL cholesterol value (mg/dL) from the same panel.
The tool subtracts HDL from total cholesterol to get non-HDL cholesterol.
Your result is classified into a risk category per ACC/AHA thresholds.
An interpretation note explains what the result means for cardiovascular risk.

Use cases

Check whether your non-HDL cholesterol meets ACC/AHA treatment targets.
Assess atherogenic lipid burden when LDL alone is unavailable or unreliable.
Monitor lipid changes after starting statin therapy or dietary changes.
Use as a quick screen before a full cardiovascular risk calculation.
