Red cell distribution width: The red cell distribution width (RDW) test

The red cell distribution width (RDW) test measures variation in red blood cell (RBC) size or RBC volume as a part of the complete blood count (CBC). It is used along with other RBC indices, especially mean corpuscular volume (MCV), to help determine the causes of anemia. It helps in the differential diagnosis of anemias and other hematological disorders. [1] RDW is elevated in accordance with variation in red cell size (anisocytosis); that is, when elevated RDW is reported on CBC, marked ...
