Reproducibility and Simplification of 13C-Octanoic Acid Breath Test for Gastric Emptying of Solids

Abstract

The 13C-octanoic acid breath test for gastric emptying of solids is as reproducible as scintigraphy. A subset of 11 sampling times provides sufficient information to characterize the whole breath-test curve, but the sampling period should be extended to 6 h after dosing.
