Suspect Large Plt Interference (NRLPLT, NP)

The Suspect Large Plt Interference flag is triggered if the system counts more
than 40,000 large platelets /μL in the RBC/PLT channel.

Suspect Lipid Interference (NR-LPD, NL)

Definition
The Suspect Lipid Interference flag is triggered if the number of signals in the
noise region of the Basophil/Lobularity Channel exceeds a specified limit when
the system reports an NRBC count.
The NR-LPD flag is triggered when both of the following conditions occur:
•
BASO % Noise > 2
•
BASO % Noise x WBCB > 10
6-50
