What LDL Particle Number measures

LDL particle number counts LDL particles directly instead of the cholesterol they carry. Reported by NMR lipid panels.

If your LDL Particle Number is low

Fewer LDL particles than the range is generally read as favorable.

Commonly associated with

Worth asking your clinician: Nothing specific; this is usually a reassuring result.

If your LDL Particle Number is high

More LDL particles than the range means more cholesterol-carrying particles in circulation, which is commonly read as higher cardiovascular risk even when LDL cholesterol looks acceptable.

Commonly associated with

Worth asking your clinician: How this compares with LDL cholesterol and ApoB, and what risk picture it paints overall.

Typical reference range

GroupTypical range
Adultsunder 1000 nmol/L

Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.

If it is within range

Your LDL particle number is within the range printed by your lab.
