Brief summary
The aim of the study is to confirm that the new generation state of the art breath analyzer gives equivalent results to the previous model of the Exalenz breath analyzer.
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.
Interventions

BreathID is the name of the original Exalenz breath analyzer system

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| DOB Peak | One hour | The DOB (Delta over Baseline) is measured before and after ingestion of challenging test substrate: 13C- Methacetin. The peak of the DOB is indicative of liver health. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of subjects with adverse events related to breath test substrate | 48 hours | Adverse events within 48 hours of the breath test will be recorded |
