Methods
8-57
The method generates four NRBC counts for every sample.
Histo count
The NRBC count from analysis of the unstained region of the Peroxidase
Channel Y-axis histogram
Gaussian count
The NRBC count from making a gaussian fit to the nRBC section of the
unstained region of the Peroxidase Channel Y-axis
Residual count
The NRBC count from subtracting the noise and lymphocytes from the unstained
region of the Peroxidase Channel Y-axis histogram
Barox count
The NRBC count from the equation #nRBC = #PMNs - #NEUTs - #EOS
The system then uses selection rules to determine which, if any, of the NRBC
counts to report.
NRBC Enumeration Histogram
The NRBC Enumeration Histogram is a
100-channel display of the light scatter
measurements and corresponds to the
unstained region of the Peroxidase Channel
Y-axis histogram. This display of the
NRBC Analysis shows overlays of:
•
Unstained Events
•
PLT Events
•
NRBC Gauss Fit
•
NRBC Residual
•
Lymph Events
The histogram also includes goalposts,
which designate the Histo and Residual
counts. These goalposts appear only when
the Histo or Residual count is the selected
NRBC count.

Calculating Reported NRBC Parameters
The system corrects the reported WBC count when nRBCs are detected.
