WebRDW is a measure of the variation in size between different RBCs and is normally less than 15%. Increased RDW may indicate the presence of abnormal RBCs (e.g., sickled cells or RBC fragments). Microscopic examination of blood smears permits identification of specific RBC abnormalities (e.g., schistocytes in microangiopathic hemolytic anemia). WebVariation in red blood cell size on a blood smear is called anisocytosis and this can be due to increased proportions of larger red blood cells than normal, smaller red blood cells than normal or a combination of both. Thus, anisocytosis has no more specific meaning other than increased variation in red blood cell size (diameter).
