Abstract
OBJECTIVES
To assess glycerol as reference material for low-resolution time-domain (1)H NMR analysis of fecal fat.
DESIGN AND 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.
