The Healthy Endoscopy Study

The Healthy Endoscopy Study

Researchers at Seattle Children's Research Institute want to find ways to understand gastrointestinal disease such as Inflammatory Bowel Disease (IBD), Irritable Bowel Syndrome (IBS) and Graft-Versus-Host-Disease (GVHD). We want to compare healthy cells from the gastrointestinal tract to cells from people with gastrointestinal diseases.
We are looking for healthy participants 18-25 with no gastrointestinal symptoms to volunteer to collect blood and stool samples and to have an upper and lower endoscopy.
We hope the information we learn in this study will help us better predict and treat these diseases in the future.
What will happen if you join this study:
1 hour appointment at Seattle Children's Hospital to determine eligibility
Blood Draw
Upper and Lower Endoscopy with tissue biopsies
Stool Sample collection
Participants will get $600 to thank them for their time.
