Location of Bands on the BASO Cytogram
Bands
appear between the
mononuclear (MN) and
polymorphonuclear (PMN)
populations.
Calculating Parameters
Reported Parameters
The following parameters are available for patient reporting:
Parameter Explanation
WBCB RawWBC x (BasoCalFactor
÷
[1-FracDT ])
%BASO 100 x (BASO Count
÷
BASO PHA Cells )
#BASO (%BASO
÷
100) x WBCB
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:
