Location of Bands on the BASO Cytogram

Calculating Parameters

Reported Parameters
The following parameters are available for patient reporting:
Parameter
WBCB
%BASO
#BASO
The system uses data from the perox channel and the baso channel to derive the
Nucleated Red Blood Cell (NRBC) count (%NRBC and #NRBC). If NRBCs are
present, the system corrects the WBC results to account for them.
Additional Parameters
The following parameters are for research or laboratory use only and are not for
patient reporting:
Parameter
%BASO Suspect
%BLAST
%MN
%PMN
%PMN Ratio
BASO % Dead Time 100 x FracDT
BASO % Noise
Methods
appear between the
Bands
mononuclear (MN) and
polymorphonuclear (PMN)
populations.
