WebThe normal range of a MCV value ranges between 80 to 96 fl (=femtoliter). This means that on average a red blood cell volume is, let’s say, 90 fl. If now the standard deviation from this curve is, let’s say, 10 fl then the RDW-CV value would be 11.1% and therefore in the normal range. The RDW-SD is an actual measurement of the width of the ...
