Non-HDL Formula:
| From: | To: |
Non-HDL cholesterol represents all atherogenic (artery-clogging) cholesterol particles in the blood. It's calculated by subtracting HDL (good) cholesterol from total cholesterol and includes LDL, VLDL, and other harmful lipid particles.
The calculator uses the simple formula:
Where:
Explanation: This calculation provides a comprehensive measure of all cholesterol particles that contribute to atherosclerosis and cardiovascular risk.
Details: Non-HDL cholesterol is considered a better predictor of cardiovascular risk than LDL alone because it accounts for all atherogenic particles. It's particularly useful when triglyceride levels are elevated.
Tips: Enter total cholesterol and HDL cholesterol values in mg/dL. Both values must be positive numbers. The calculator will automatically compute your non-HDL cholesterol level.
Q1: What is a healthy non-HDL cholesterol level?
A: Optimal non-HDL cholesterol is less than 130 mg/dL. For high-risk patients, targets may be lower (<100 mg/dL or even <70 mg/dL).
Q2: Why is non-HDL better than LDL cholesterol?
A: Non-HDL includes all atherogenic particles (LDL, VLDL, IDL) while LDL only measures one type. This provides a more complete picture of cardiovascular risk.
Q3: When should non-HDL be measured?
A: Non-HDL should be calculated as part of routine lipid panel assessment, especially in individuals with elevated triglycerides, diabetes, or metabolic syndrome.
Q4: How can I lower my non-HDL cholesterol?
A: Lifestyle modifications (healthy diet, regular exercise, weight management) and medications (statins, other lipid-lowering drugs) can help reduce non-HDL levels.
Q5: Is fasting required for non-HDL calculation?
A: Unlike LDL calculation, non-HDL can be accurately calculated from non-fasting blood samples, making it more convenient for patients.
