Red blood cell distribution width (RDW), as well as various types thereof (RDW-CV or RCDW and RDW-SD), is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. [1]
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
The red cell distribution width (RDW) is a measurement of anisocytosis [1] and is calculated as a coefficient of variation of the distribution of RBC volumes divided by the mean corpuscular volume . Types
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]

An increased red cell distribution width (anisocytosis) also suggests megaloblastosis and is commonly seen in Vitamin B 12 deficiency and folate deficiency. [1] This type of anemia is caused by impaired DNA synthesis and repair, often from deficient thymidine production. [1] Thiamine responsive megaloblastic anemia syndrome also causes ...

Any deviation would usually be indicative of either faulty equipment or technician error, although there are some conditions that present with high MCV without megaloblastic cells. For further specification, it can be used to calculate red blood cell distribution width (RDW). The RDW is a statistical calculation made by automated analyzers that ...
