RBC Fragments (RBCF)
Definition
The presence of RBC fragments is suspected.
This flag is triggered if the number of events in the RBC Fragment area of the
PLT Scatter cytogram is greater than 100,000 cells/µL. The event count in this
area includes red blood cell fragments with volumes less than 30fL and refractive
indexes greater than 1.400.
RBC fragments are excluded from the PLT count and the RBC count.
There are no severity levels associated with this flag.

1 RBC Ghost area
2 Platelet area
3 RBC Fragment area
NOTE
Whenever the ratio of RBC fragments to platelets exceeds 0.25, the system uses
the log normal fit calculation to determine the platelet count, and the log normal
fit curve appears on the Platelet Volume histogram.
The RBC Fragment value is intended for flagging and laboratory purposes only.
