Anisocytosis (ANISO)
Definition
The Anisocytosis flag is triggered if variation in RBC volume (RDW) is equal to
or greater than 16%. The Red Cell Distribution Width (RDW) parameter is the
coefficient of variation of the cell volume distribution on the RBC volume
histogram.
Default trigger values for the three severity levels are:
+ RDW = 16.0% to 17.9%
++ RDW = 18.0% to 22.0%
+++ RDW > 22.0%
