Large Platelets (LPLT)

Definition
The Large Platelets flag is triggered if the percentage of large platelets (%LPLT)
is greater than 10% of the platelet count.
The %LPLT parameter indicates the percent of platelets with volumes greater
than 20 fL. This parameter is derived from the Platelet Volume histogram based
on Integrated Analysis.
Default trigger values for the three severity levels are:
+
++
+++
The %LPLT value is intended for flagging and laboratory purposes only.
