Assessing the Utility of Quantitative Fecal Fat Studies to Diagnose Small Intestinal Bacterial Overgrowth (SIBO)

Overview

About this study

The purpose of this study is to understand how the results from a fecal fat test compare to results from the duodenal aspirate culture which was collected during a recent clinical EGD. The goal is to determine whether this less expensive, non-invasive test that can be performed at home can potentially be used in place of an EGD with fluid collection and culture, particularly to monitor response to treatment.

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
