Detailed Description
Healthy and chronic liver disease subjects of all grades will be tested to see that the two devices give equivalent results in both devices. Subjects will be connected to both devices at the same time and will be tested for one hour.
The breath test includes automatic baseline breath collection, 13C-Methacetin ingestion in solution and breath collection post ingestion.
