A method for determining gastric emptying consisting essentially of
- determining 13CO2 content in exhaled respiratory air of a patient, followed by
- orally administering to the patient free 13C-octanoic acid together with a standardized test meal, wherein the free 13C-octanoic acid is in a form bound to egg yolk, followed by
- determining 13CO2 content in exhaled respiratory air of the patient, wherein body-related conversion factors are dispersed with.
A method for determining gastric emptying consisting essentially of, in the absence of using body-related conversion factors,
- determining 13CO2 content in exhaled respiratory air of a patient, followed by
- orally administering to the patient free 13C-octanoic acid together with a standardized test meal, wherein the free 13C-octanoic acid is in a form bound to egg yolk, followed by
- determining 13CO2 content in exhaled respiratory air of the patient.
