Core Tip

Core tip: Mounting evidences show that red blood cell distribution width can be used as a prognostic marker in gastrointestinal disorders. A number of retrospective studies have been published about the use of this index of anisocytosis in prognostication of gastrointestinal disorders, especially inflammatory bowel disease and viral hepatitis among others. However, only a few have included confounding factors which could affect red blood cell distribution width. Our objective is to consolidate the current literature to better understand the use and further investigate the significance of red blood cell distribution width in gastrointestinal disorders.
