Brief summary

The purpose of the study is to develop a clinical test based on breath analysis that can be used for disease diagnosis or prognosis.

Detailed description

The study will seek to collect and analyze breath samples from a broad range of patients to develop reference ranges and to refine the testing methods. Protocols for breath sample collection and algorithms for analysis will be developed. Samples will be collected from normal volunteers, persons with documented liver disease, organ transplant or with known COVID-19 test results.

Recruitment details

Participants were enrolled from a specialized liver clinic. There was a need to ensure that sample collection and analysis could be performed within a controlled environment that did not pose risk of exposure or transmission of COVID-19 virus. As this could not be assured at the time, participants were not enrolled for the COVID-19 and other arms.
