Nuclear Magnetic Resonance Lipoprotein Profile, Serum
Use
The Nuclear Magnetic Resonance Lipoprotein Profile is useful for the assessment and management of a patient's risk for atherosclerotic cardiovascular disease (ASCVD). This test helps identify residual risk that may be present in some patients receiving cholesterol-targeting treatment by measuring lipoprotein particles through Nuclear Magnetic Resonance (NMR). LDL-P concentration is positively associated with increased risk of ASCVD, and is considered a more accurate reflection of risk compared to LDL cholesterol values alone. HDL-P concentration inversely correlates with ASCVD risk, even amongst those on cholesterol-lowering medications.
Special Instructions
The patient must fast for 12 hours, and should avoid fatty foods and alcohol 24 hours prior to specimen collection. Use a red top collection container, centrifuge and aliquot serum into a plastic vial. Not ordering electronically requires a Cardiovascular Test Request Form (T724).
Limitations
The test may be hindered by failure to follow specimen collection requirements, which could prevent measurable results. Additionally, gross hemolysis, lipemia, or icterus may cause specimen rejection. Moreover, reference values are not established for patients younger than 18 years of age, which could limit applicability.
