Lipoprotein Analysis (NMR) Test in South Dakota

A lipoprotein analysis (NMR) test is a blood test that uses nuclear magnetic resonance to measure the number and size of lipoprotein particles in your blood. It is often ordered when a standard cholesterol panel leaves questions about cardiovascular risk, because particle number and size can add detail beyond LDL, HDL, and triglycerides alone.

What it measures

LDL particle number (LDL-P) — How many LDL particles are circulating; a higher number may suggest more risk than LDL cholesterol alone.
Small LDL particle number — Counts the smaller, denser LDL particles, which may be more likely to contribute to artery plaque.
HDL particle number (HDL-P) — How many HDL particles are present; HDL helps carry cholesterol away from arteries.
Large VLDL particle number — Counts larger triglyceride-rich particles that can be a marker of metabolic risk.
LDL particle size — Reports whether LDL particles are mostly large or small; pattern can inform risk assessment.
Triglycerides and total cholesterol — Standard lipid values are usually reported alongside the particle measurements.

Who it is for

This test is typically ordered by a clinician for adults with a personal or family history of early heart disease, diabetes, or other risk factors, especially when standard lipid results do not fully explain risk. It may also be used to monitor response to lifestyle or medication changes.

Preparation

Fasting for 9 to 12 hours is often recommended because triglyceride levels can affect particle measurements; follow the instructions given by your clinician or lab. Some labs allow non-fasting testing, so confirm before your appointment.

Results and what they mean

Results are reported as particle counts and sizes, often with a risk category or percentile for each measure. A clinician interprets these numbers together with your medical history, other lab tests, and risk factors; results alone do not diagnose a condition. This is general information, not medical advice.

Frequently asked questions

How is this test different from a standard cholesterol panel?

A standard panel measures cholesterol carried in LDL, HDL, and other fractions. The NMR test counts the actual particles and can report their sizes, which may give a clearer picture of risk for some people.

Does the test hurt?

It uses a standard blood draw from a vein in your arm, so you may feel a brief pinch or sting. The sample is then analyzed by a machine.

Can I eat before the test?

Many labs ask you to fast for 9 to 12 hours, but some allow non-fasting samples. Check with your clinician or the lab to be sure.

When will I get results?

Typical turnaround is 1 to 3 business days, though this can vary by lab. Your clinician will review the results with you.
