Abnormal Cell Locations

If abnormal cells are present, their size and nuclear configuration determine the
location of their signals on the BASO cytogram. Click the cytogram buttons
below to see where the abnormal cells will appear.
Location of Blasts on the BASO Cytogram
Methods
This threshold (shown as a
red line) is set at channel 8
on the x axis and between
channels 4 and 21 on the y
axis.
All cells below (to the left
of) this threshold are
counted as Blasts, which are
monitored for flagging
purposes only.
The Blast count should not
be reported as a patient
result.
The "valley" threshold
(shown as a red line)
separates the Mononuclear
(MN) and
Polymorphonuclear (PMN)
populations.
The valley threshold is a
floating threshold that is set
using the Baso X histogram.
