Red Cell Distribution Width (RDW)
|To use the RDW and MCV to suggest the likely cause for anemia.|
|laboratory tests, other testing|
|D50-D53, D55-D59, D60-D64, D65-D69, D70-D77|
The Red Cell Distribution Width (RDW) is the coefficient of variation of the red blood cell size as determined on automated blood cell counting instruments. It is a measure of anisocytosis. It has limited value in patients without anemia.
