remnant cholesterol
Cholesterol carried in triglyceride-rich lipoprotein remnants, calculated as total cholesterol minus LDL and HDL cholesterol.
Full Definition
Remnant cholesterol represents the cholesterol content of partially metabolized triglyceride-rich lipoproteins, including VLDL remnants and chylomicron remnants. It is typically calculated as total cholesterol minus LDL cholesterol minus HDL cholesterol, though direct measurement methods are being developed. Elevated remnant cholesterol is increasingly recognized as an independent cardiovascular risk factor, particularly in patients with diabetes, metabolic syndrome, or hypertriglyceridemia. Normal levels are generally considered to be less than 30 mg/dL (0.8 mmol/L), with values above 40 mg/dL (1.0 mmol/L) considered significantly elevated.
Usage
Usage note: Distinguish from VLDL cholesterol, which is only one component; avoid abbreviated forms in formal writing.
