Non-HDL Cholesterol

The normal reference range for Non-HDL Cholesterol is Calculated as total cholesterol minus HDL. Below 2.5 mmol/L is desirable for most adults, with a target around 2.0 mmol/L for those at high cardiovascular risk. It does not require fasting and is reliable even when triglycerides are high.. Reference ranges may vary between laboratories, so always consult your healthcare provider for interpretation.

Provides a more comprehensive assessment of cardiovascular risk than LDL alone and is a risk marker for dyslipidemia and metabolic syndrome.

Non-HDL captures every artery-damaging particle (LDL plus VLDL and other triglyceride-rich remnants), so it rises with the same factors that raise LDL and triglycerides: a diet high in saturated fat and refined carbohydrate, obesity, insulin resistance and type 2 diabetes, hypothyroidism, kidney disease and familial lipid disorders. It is particularly useful in people with diabetes or high triglycerides, where LDL alone underestimates risk.

A low non-HDL is favourable and is the goal of lipid-lowering treatment. Naturally low values can reflect an overactive thyroid, malnutrition, malabsorption or liver disease, in which case the underlying cause matters more than the number itself.

Non-HDL is calculated from every standard lipid panel, so it follows lipid screening intervals: every 5 years for healthy adults, and 6-12 weekly after a therapy change until stable, then every 6-12 months.
