Microcytosis (MICRO)
Definition
The Microcytosis flag is triggered if the percentage of red blood cells with lower
than normal cell volumes (%MICRO) is equal to or greater than 2.5%.
The %MICRO parameter indicates the percent of red blood cells that have a
volume equal to or lower than 60 fL and is derived from the RBC volume
histogram.
Default trigger values for the three severity levels are:
+
%MICRO = 2.5% to 6.4%
++
%MICRO = 6.5% to 10.5%
+++ %MICRO
>
10.5%
The %MICRO value is intended for flagging and laboratory purposes only.
