Stool tests could make IBD monitoring easier and cheaper
NCT ID NCT06623383
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 120 adults with inflammatory bowel disease (IBD) to see if simple stool tests can tell if the disease is active or in remission, just like a colonoscopy does. Colonoscopy is the current gold standard but is expensive, invasive, and not ideal for frequent checks. The researchers compared two stool tests—calprotectin and fecal immunochemical test—with colonoscopy results to see how well they match. The goal is to find a simpler, less costly way to monitor IBD over time.
