Non-HDL cholesterol is your total cholesterol minus your HDL cholesterol. What is left is the cholesterol carried by every type of particle that can build plaque, not only LDL.
You can work it out from any standard lipid panel at no extra cost. It is a more dependable guide than LDL cholesterol when your triglycerides are high, because that is when the usual LDL figure is most likely to read too low.
Key takeaways
- The sum is simple: total cholesterol minus HDL cholesterol.
- Non-HDL includes LDL plus the remnant particles that an LDL number leaves out.
- Treatment goals for non-HDL sit 30 mg/dL above the matching LDL cholesterol goal.
- It works without fasting and stays reliable when triglycerides are raised.
- ApoB goes one step further by counting particles instead of measuring their cholesterol.
What non-HDL cholesterol includes
Cholesterol travels in several kinds of particle. HDL is the only one not linked to plaque build-up. Everything else is: LDL, the triglyceride-rich particles made by the liver and their remnants, and Lp(a).
LDL cholesterol counts the cholesterol in just one of those groups. Non-HDL cholesterol counts all of them together. When most of your harmful cholesterol is in LDL, the two numbers tell the same story. When a lot of it sits in remnant particles, as happens with high triglycerides, non-HDL catches what LDL misses.
How to calculate it
Take two numbers from your report and subtract.
- Total cholesterol: 210 mg/dL
- HDL cholesterol: 50 mg/dL
- Non-HDL cholesterol: 210 minus 50 = 160 mg/dL
Many labs now print non-HDL on the report. If yours does not, the sum takes a few seconds. Both inputs are measured directly, which is part of the appeal.
You do not need to have fasted. After an ordinary meal, calculated non-HDL cholesterol changes by only about 8 mg/dL on average.1
Why it beats LDL cholesterol when triglycerides are high
On most lab reports LDL cholesterol is not measured. It is estimated with a formula that uses your triglyceride level to guess how much cholesterol sits in non-LDL particles. The standard formula assumes a fixed ratio of 5 between triglycerides and that cholesterol.2
In real blood samples the ratio differs from person to person, and the estimate drifts as triglycerides climb. A study of more than 1.3 million lipid profiles checked the formula against direct measurement. Among samples with triglycerides of 150 to 199 mg/dL and an estimated LDL cholesterol below 70 mg/dL, only 61% were truly below 70 when measured directly.2
In other words, the formula can make LDL look lower than it is, and it does so in the people whose triglycerides are raised. Non-HDL cholesterol avoids the issue because it involves no estimate.
What the numbers mean
There is no single "normal" non-HDL level. The 2026 ACC/AHA guideline restored treatment goals for it and tied them to your risk category.
| Risk category | LDL cholesterol goal | Non-HDL cholesterol goal |
|---|---|---|
| Borderline or intermediate 10-year risk | Below 100 mg/dL | Below 130 mg/dL |
| High 10-year risk | Below 70 mg/dL | Below 100 mg/dL |
| Established cardiovascular disease at very high risk | Below 55 mg/dL | Below 85 mg/dL |
In the 2026 guideline, the non-HDL cholesterol goal is set 30 mg/dL above the matching LDL cholesterol goal in each main risk category.3
These are goals for people in whom lowering cholesterol is being pursued. They are not definitions of health for everyone. Your category depends on your age, blood pressure, diabetes status and other factors, which we explain in LDL goals by risk category.
How well it predicts risk
The evidence for non-HDL cholesterol is large and consistent.
In a study that followed 398,846 people in 19 countries, the 30-year rate of cardiovascular events rose from 7.7% in women with the lowest non-HDL cholesterol to 33.7% in women with the highest. In men the range was 12.8% to 43.6%.4 The lowest group had levels below about 100 mg/dL. The highest had levels of about 220 mg/dL or more.
A meta-analysis of 12 studies with 233,455 participants ranked three markers by how strongly they predicted cardiovascular events. ApoB was the strongest, LDL cholesterol the weakest, and non-HDL cholesterol in between.5
The advantage holds on treatment too. In a study of 13,015 people taking statins, those with high non-HDL cholesterol despite low LDL cholesterol had a 78% higher risk of heart attack than those with both low.6
Where non-HDL stops being enough
Non-HDL cholesterol still measures cholesterol, not particles. Two people with the same non-HDL result can have different numbers of particles, because some particles carry more cholesterol than others. Since each particle can enter the artery wall, the count matters.
ApoB measures that count directly. Non-HDL and ApoB usually agree. When they do not, lipid specialists generally treat ApoB as the more precise measure. Think of non-HDL as the best number you can get from a routine panel, and ApoB as the test to add when the picture is unclear.
Non-HDL cholesterol and a Cardio Res-Q assessment
Both Cardio Res-Q assessments measure ApoB, the particle count that non-HDL cholesterol approximates, along with Lp(a), hs-CRP, insulin, glucose and A1c. The Comprehensive Assessment is $775 and the Enhanced Assessment, which adds imaging, is $999.
Non-HDL cholesterol comes from a standard lipid panel, which the program page does not itemize. Ask our team whether one is drawn at your visit. If you have a recent panel from your own doctor, see bringing outside test results. To book, go to the Cardio Res-Q program page.

Frequently asked questions
Is non-HDL cholesterol on my lab report?
Often, yes. Look for a line labeled "non-HDL cholesterol" near the total. If it is not there, subtract your HDL cholesterol from your total cholesterol to get it.
What is a good non-HDL cholesterol level?
It depends on your risk. Guideline goals range from below 130 mg/dL for people at borderline or intermediate risk down to below 85 mg/dL for people with established disease at very high risk. Your clinician can tell you which applies to you.
If I know my non-HDL, do I still need ApoB?
Not always. If your non-HDL cholesterol is clearly low or clearly high, ApoB may not add much. It helps most when triglycerides are high, when you have diabetes or insulin resistance, or when LDL cholesterol is already low on treatment.
Does a high HDL make my non-HDL result better?
A higher HDL lowers the result of the subtraction, but that does not mean HDL is protecting you. What matters is how much cholesterol is left in the particles that build plaque.
