An endoscopy is the most accurate diagnostic test for identifying the source of upper gastrointestinal bleeding. It allows for direct visualization and potential treatment of the bleeding source. Angiography may be used if the bleeding source is unclear, but it is not as accurate as endoscopy. Gastric analysis and barium contrast studies are not typically used to diagnose sources of gastrointestinal bleeding.
