Dr. Li Qinghui
Red blood cell distribution width (RDW) is a measure of the variation in red blood cell volume within the bloodstream. A low RDW is commonly associated with iron-deficiency anemia and thalassemia. Patients should receive treatment targeted to the underlying cause and, in daily dietary practice, consume more iron-rich foods.
