Lipoprotein Analysis (NMR) Test in Wisconsin

What this test is

Lipoprotein Analysis (NMR) is a blood test that measures the size and number of different types of lipoprotein particles in your blood. These particles are responsible for transporting cholesterol and other fats throughout your body.

What it measures

• LDL Particle Number (LDL-P) — reflects the total number of low-density lipoprotein particles
• HDL Particle Number (HDL-P) — reflects the total number of high-density lipoprotein particles
• LDL Particle Size — reflects the average size of low-density lipoprotein particles
• HDL Particle Size — reflects the average size of high-density lipoprotein particles
• VLDL Particle Number (VLDL-P) — reflects the total number of very-low-density lipoprotein particles
• Remnant Cholesterol — reflects cholesterol within triglyceride-rich lipoprotein remnants

What the test involves

This test requires a standard blood draw from a vein in your arm. The collected blood sample is then sent to a laboratory for analysis.

Why it is often ordered

Clinicians often order this test to get a more comprehensive understanding of cardiovascular risk beyond standard cholesterol levels. It can help identify specific patterns of lipoprotein that may be associated with increased health concerns.

Preparation

You will need to follow the specific preparation instructions provided by the laboratory where you will have your blood drawn. This may include fasting for a certain period before the test.

How results are reported

Your results will be reported by the laboratory, detailing the levels of various lipoprotein components. Reference ranges can vary between laboratories, so it is important to discuss your results with your healthcare provider.
