RDW-CV "width" refers to the width of the volume curve (distribution width), not the width of the cells. [5] [6] RDW-SD is calculated as the width (in fL) of the RBC size distribution histogram at the 20% height level. This parameter is, therefore, not influenced by the average RBC size (mean corpuscular volume, MCV). [7]
Red blood cell distribution width (RDW or RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume, yielding clues about morphology. [ citation needed ] Erythropoietic precursor indices
A blood smear can be used to view individual red blood cells. The diameter of each red blood cell can be measured, which is usually analogous to volume. [2] This is usually performed automatically by particle counters. [2] [4] Data is then converted into a histogram. [1] This can be used to assess red blood cell distribution width (RDW). [1] [4]
The mean corpuscular volume, or mean cell volume (MCV), is a measure of the average volume of a red blood corpuscle (or red blood cell). The measure is obtained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit ), and dividing that product by the number of erythrocytes (red blood cells) in that volume.
Anisocytosis is a medical term meaning that a patient's red blood cells are of unequal size. This is commonly found in anemia and other blood conditions. False diagnostic flagging may be triggered on a complete blood count by an elevated WBC count, agglutinated RBCs, RBC fragments, giant platelets or platelet clumps due to anisocytosis.
The index is calculated from the results of a complete blood count. If the quotient of the mean corpuscular volume (MCV, in fL) divided by the red blood cell count (RBC, in million per microliter) is less than 13, β-thalassemia trait is said to be more likely. If the result is greater than 13, then iron-deficiency anemia is said to be more likely.

A complete blood count includes red blood cell (RBC), white blood cell (WBC), hemoglobin, and platelet counts, as well as hematocrit levels. Other analyses include: [citation needed] RBC distribution width; Mean corpuscular volume; Mean corpuscular hemoglobin; Mean corpuscular hemoglobin concentrations; WBC differential count in percentage and ...
