A member asked:

What is rdw for bloodwork and what does it mean when it's high. all others normal. ?

A doctor has provided 1 answer

Size variation: It means nothing by itself; plus, hopefully you know that all lab reference ranges are set so that a few percent of healthies fall outside on either end. Early iron deficiency raises RDW before anemia begins but often it's up for no apparent reason. Mine's usually high because I donate blood. Don't worry about it.
