WebRDW-SD and RDW-CV are parameters that are analyzed as part of the red blood cell blood analysis: RDW-CV = Coefficient of Variation. RDW-SD = Standard Deviation. One important factor to mention now is that when we are looking at the red cell distribution width, we are not looking at the actual width (or diameter) of the individual red blood cells. WebA coefficient of variation (CV) can be calculated and interpreted in two different settings: analyzing a single variable and interpreting a model. The standard formulation of the CV, the ratio of the standard deviation to the mean, applies in the single variable setting. In the modeling setting, the CV is calculated as the ratio of the root ...
