Swallow this capsule: could it replace scopes for hidden bleeding?

This study tests a small, swallowable capsule called PillSense™ that can detect blood in the upper digestive tract in about 10 minutes. Researchers want to see if a negative result from the capsule can safely rule out serious bleeding, so patients with anemia or a positive stool test might avoid an invasive endoscopy and be discharged sooner. The study involves 20 hospitalized adults and will compare capsule results with standard care to measure accuracy and safety.
