A 4 Diff Alarm
The 4DIFF populations are not clearly distinguishable
on the scatter diagram.
If other parameters predict a ‘normal’ sample then
perform a cleaning procedure and repeat the
measurement.
If 4DIFF results reported then treat them as ‘reduced
reliability’. If not all the parameters reported or the
sample is predicted as pathological then perform a
manual count on a stained smear.
B WBC blank is high WBC > WBC blank high limit
Check cleanliness of the reagents and the ‘ELite 5’.
Perform cleaning of the ’ELite 5’. Repeat blank
measurement. See chapter: 6.2.5:Pneumatics start
and blank measurement
Treat WBC result as ‘reduced reliability’.
b RBC blank is high RBC > RBC blank high limit
Check cleanliness of the reagents and the ‘ELite 5’.
Perform cleaning of the ’ELite 5’. Repeat blank
measurement See chapter: 6.2.5 :Pneumatics start
and blank measurement
Treat RBC result as ‘reduced reliability’.
C WBC clogging
Drift in the probe voltage of the WBC capillary. The
two main reasons for this drift are the misconnected
reagent and the clogging of the capillary.
Check the reagent connections.
Perform a cleaning procedure! See chapter:
Maintenance.
Please repeat the measurement.
c RBC/PLT clogging
Drift in the probe voltage of the RBC capillary. The two
main reasons for this drift are the misconnected
reagent and the clogging of the capillary.
Check the reagent connections.
Perform a cleaning procedure! See chapter:
Maintenance.
Please repeat the measurement.
