NMR Small LDL-P

Small LDL-P

A direct count of small, dense LDL particles.

What is it

NMR Small LDL-P — in plain English.

Small LDL-P measures the number of small, dense LDL particles specifically. These particles have been studied as a more atherogenic subfraction of LDL.

Why it's measured

What Small LDL-P can reveal.

Elevated small LDL-P has been linked to insulin resistance and cardiovascular risk in published research.

Reference range

Where most laboratories draw the standard line.

Standard laboratory reference

< 600 nmol/L

Reference ranges vary by laboratory. Your individual reference range will appear on your test report and should be interpreted by your physician in the context of your overall health profile.

What results may indicate

Higher vs. lower Small LDL-P — at a high level.

Elevated

Has been associated with insulin resistance and cardiovascular risk in research literature.

Lower

Is generally considered favorable in published research.

These associations are general. They are not a personal diagnosis or prediction. Discuss your individual results with your physician in the context of your full health profile.

When it's measured

When Small LDL-P is typically run.
