The breath test system involving a novel tracer, ¹³C-uracil and Wagner-Nelson analysis: comparison with the gastric emptying scintigraphy.

In this pilot study, a new breath test system for gastric emptying study has been proposed.The system involves 13C-uracil as a novel tracer and the Wagner-Nelson method for analyzing breath data.In three healthy volunteers, the new breath system allowed quantification of gastric emptying profiles as accurately as the scintigraphic technique.Further validation studies with a lager sample size are needed.
