Red Blood Cell Distribution Width Calculator
Posted by Dinesh onThis calculator calculates the red blood cell distribution width (rdw or rdw-cv or rcdw and rdw-sd) using standard deviation of mcv, mcv values.
Measure the Range of Variation of Red Blood Cell (RBC) in Blood Count
The "width" in RDW-CV is sometimes thought to be "misleading," since it in fact is a measure of deviation of the volume of RBCs, and not directly the diameter. However, "width" refers to the width of the volume curve (distribution width, here presented as the coefficient of variation, or CV), not the width of the cells. Thus, it is a reasonably accurate term.
