Glycerol as a reference material for fecal fat quantitation using low-resolution time domain ¹H NMR spectroscopy.

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.
