Remnant Cholesterol
This is the figure that explains vascular risk persisting despite a normal LDL. It captures cholesterol carried in triglyceride-rich lipoproteins, which an LDL measurement does not see.
Your numbers
Remnant cholesterol
33mg/dL
Non-HDL
158mg/dL
Percentage
15.7%
What it means
33 is high; this is where risk that survives a normal LDL shows up.
Formula
Remnant cholesterol = Total cholesterol − HDL − LDL
Use total, HDL and LDL from the same panel on the same day. Mixing dates can even produce a negative number.
What to enter
| Input | Default | Accepted range |
|---|---|---|
| Total cholesterolAll the cholesterol in the blood, added up. | 210 | 80 ~ 500 |
| HDLThe kind that carries cholesterol back to the liver — higher is better. | 52 | 10 ~ 120 |
| LDLThe kind that builds up in artery walls — lower is better. | 125 | 20 ~ 350 |

What each result means
| Result | At default values |
|---|---|
| Remnant cholesterol (mg/dL)What is left after HDL and LDL — an LDL test does not see it. | 33 |
| Non-HDL (mg/dL)Everything except HDL. | 158 |
| Percentage (%)A share expressed out of 100. | 15.7 |
Common mistakes
Use total, HDL and LDL from the same panel on the same day. Mixing dates can even produce a negative number.

Frequently asked questions
Q. How is Remnant Cholesterol calculated?
Remnant cholesterol = Total cholesterol − HDL − LDL — This is the figure that explains vascular risk persisting despite a normal LDL. It captures cholesterol carried in triglyceride-rich lipoproteins, which an LDL measurement does not see.
Q. Can you walk through an example?
With Total cholesterol 210, HDL 52, LDL 125, the answer is Remnant cholesterol 33mg/dL.
Q. What do I need to enter?
Enter Total cholesterol, HDL, LDL. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Total cholesterol moves the answer to Total cholesterol 105 → Remnant cholesterol (mg/dL) -72 and Total cholesterol 420 → Remnant cholesterol (mg/dL) 243. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Use total, HDL and LDL from the same panel on the same day. Mixing dates can even produce a negative number.
