Lipoprotein Profile by Nuclear Magnetic Resonance (NMR), Serum
Orderable by Ontario ND
Test Overview
Clinical Utility
Assessment and management of a patient’s risk for atherosclerotic cardiovascular disease.
Identifying residual risk that may be present in some patients on cholesterol targeting treatment.
Method
Nuclear magnetic resonance spectroscopy (NMR)
Method Description
Lipoprotein particles are quantified in serum by nuclear magnetic resonance (NMR). The deconvoluting algorithm used is the AXINON Mayo LP Profiler software.(AXINON System User Manual Version 1.3.2, 3/2018)
Result Included
LDL Particles; HDL Particles; LDL Cholesterol (NMR), S
Aliases/Synonyms
Lipoprotein particles; LDL particle number; HDL particle number
