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