<P> Red cell distribution width (RDW): reflects the degree of variation in size and shape of red blood cells as calculated by automated analyzers . RDW determination, in conjunction with RBC count and MCV, is useful in the interpretation of several hematological disorders . The RDW is measured as a coefficient of variation of red cell size distribution . </P> <P> Platelet numbers are given, as well as information about their size and the range of sizes in the blood . </P> <P> Mean platelet volume (MPV): a measurement of the average size of platelets . </P> <P> An example of reference ranges for a complete blood count . Note that test names, measurement units and reference ranges may vary between countries and laboratories . Patient results should always be interpreted using the units and reference ranges from the laboratory that produced the results . </P>
