title: Glycerol as a reference material for fecal fat quantitation using low-resolution time domain ¹H NMR spectroscopy.
abstract: OBJECTIVE
  To assess glycerol as reference material for low-resolution time-domain (1)H NMR analysis of fecal fat.
  
  
  METHODS
  NMR analysis of fecal fat in stool samples with added glycerol was used to assess linearity, recovery, and relationship with NMR lipid signal.
  
  
  RESULTS
  The study revealed for added glycerol excellent linearity (r=0.9998), recovery (101-104%), and linear relationship with simulated fecal fat content.
  
  
  CONCLUSIONS
  Glycerol is an effective reference material for NMR fecal fat analysis.
