- Original description
This study will evaluate how well the a new stool test can distinguish inflammatory bowel disease (IBD) from non-IBD conditions compared with standard calprotectin testing and colonoscopy findings. Participants will undergo only routine clinical care, including colonoscopy, and will provide a stool sample for testing. The study will also examine how test results relate to endoscopic, histologic, and ultrasound measures of disease activity. Findings may help determine whether the new test could reduce unnecessary colonoscopies and support future regulatory submissions.Read full original descriptionShow less
