Validation of Breath Test Prototype

Condition

  • Small intestinal bacterial overgrowth


Study Name

Validation of a Point-of-Care Breath Test Prototype Gas Chromatograph
(IRB no. 42911)


Summary

The purpose of this study is to evaluate an investigational method of breath testing. Researchers aim to determine whether analysis of an additional gas, hydrogen sulfide, will improve their ability to diagnose and treat patients with small intestinal bacterial overgrowth (SIBO). The study will compare breath gas testing that includes measurement of hydrogen sulfide to the standard testing, which measures only methane and hydrogen gas.

The study will be conducted in just one visit. Breath testing will be taken and read by the standard testing method, as well as by the new prototype analyzer.
