8-55
RBC Ghosts
This count includes events in the RBC Ghost area of the PLT Scatter cytogram
that have refractive indexes lower than 1.350.
1 RBC Ghost area
2 Platelet area
3 RBC Fragment area
The RBC Ghosts Count is in the same units selected for RBC on the Unit Set
Configuration window of the System Setup tab.
MPC
Mean Platelet Component Concentration
MPM
Mean Platelet Dry Mass
PCDW
Platelet Component Distribution Width
PDW
Platelet Volume Distribution Width
PMDW
Platelet Dry Mass Distribution Width
PCT
Platelet Crit
RBC Fractional Dead Time
The fraction of time that the channel is busy processing flowcell events. While
the RBC/Plt channel is busy identifying a particular flowcell event, it is unable to
process any additional events that might occur. By measuring this "dead time",
the analyzer can compensate for the missed events.
Note that the RBC / Plt channel dead time has RBC and platelet components.
Corrected Platelet Count
The corrected platelet count is calculated using the P Count-2D , R Count-2D
RBC Fractional Dead Time , and RBC Valid Cells.
P Count-2D
The number of cells identified as platelets and large platelets. The platelets are
obtained from the PLT Scatter cytogram, and the large platelets are obtained
from the integrated analysis.
R Count-2D
The count of RBCs, RBC ghosts, and RBC fragments that is obtained from the
integrated analysis.
Number of red cells-2D
(R Count-2D x RBC Valid Cells)
÷
(R Count-2D + P Count-2D)
