Abnormal Cell Locations
If abnormal cells are present, their size and peroxidase activity determine their
location on the PEROX cytogram.
Location of nRBCs on PEROX Cytogram
Nucleated Red Blood
Cells (nRBCs)
appear in
the NRBC cluster (1), which
is located between the Noise
and Lymphocyte areas.
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.
Location of Atypical Lymphocytes
on PEROX Cytogram
Atypical
lymphocytes
are
large cells with no
peroxidase activity
that can appear in
the LUC area (1).
Location of Blasts on PEROX Cytogram
Similarly,
blasts
and other large
abnormal cells
with no peroxidase
activity also appear
in the LUC area
(1).
