Non-HDL Cholesterol Calculator
Calculate your non-HDL cholesterol level to better assess cardiovascular risk.
Understanding Non-HDL Cholesterol
Non-HDL cholesterol is a critical metric in cardiovascular health because it measures all the "bad" types of cholesterol in your blood. While LDL (low-density lipoprotein) is the most famous type of bad cholesterol, non-HDL accounts for LDL plus other lipoproteins like VLDL (very-low-density lipoprotein) and IDL (intermediate-density lipoprotein).
The Formula
The calculation is straightforward. It does not require fasting or complex blood work beyond a standard lipid panel. The formula is:
Non-HDL Cholesterol = Total Cholesterol – HDL Cholesterol
Why Non-HDL Matters More Than LDL Alone
Medical professionals increasingly focus on Non-HDL because it includes all atherogenic (plaque-forming) particles. Even if your LDL levels appear "normal," a high Non-HDL level can indicate a significant risk of heart disease, especially for individuals with high triglycerides or diabetes.
Reference Values (mg/dL)
| Category | Target Non-HDL Level |
|---|---|
| Optimal | Less than 130 mg/dL (3.4 mmol/L) |
| Borderline High | 130 – 159 mg/dL (3.4 – 4.1 mmol/L) |
| High | 160 – 189 mg/dL (4.1 – 4.9 mmol/L) |
| Very High | 190 mg/dL and above (4.9 mmol/L +) |
Calculation Example
Suppose an individual has a Total Cholesterol of 210 mg/dL and an HDL of 45 mg/dL.
- Calculation: 210 – 45 = 165 mg/dL.
- Interpretation: This individual falls into the "High" category for Non-HDL, suggesting a need for lifestyle changes or consultation with a physician, even if their LDL alone seemed lower.
How to Improve Your Numbers
To lower your Non-HDL cholesterol, focus on increasing soluble fiber (oats, beans), reducing saturated and trans fats, and engaging in regular cardiovascular exercise. Maintaining a healthy weight and quitting smoking are also primary factors in improving your overall lipid profile.
