NMR LipoProfile
INSULIN RESISTANCE
Plasma lipoprotein particle sizes and concentrations were analyzed by proton nuclear magnetic resonance (NMR) spectroscopy at LabCorp (LipoScience, Inc.). This analysis, certified according to the Clinical and Laboratory Standards Institute EP5-A2 guidelines, uses NMR to estimate the number and size of lipoprotein particles within the lipoprotein subclasses, including very-low-density lipoprotein, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) particles from small to large, reporting a calculated lipoprotein insulin resistance index [
