A member asked:

High rcdw in a blood test. is it bad?

A doctor has provided 1 answer

Big picture: Red cell size distribution width can be high simply from donating blood, or from early iron deficiency before anemia or any of several non-problems. And reference ranges are set so that several percent of healthies fall outside. Your history, physical exam and other labs are what matter; ignore a lone high rdw.
