Out-of-linear range indicators (WBC, HGB, RBC, PLT)
AL – Result is above
linearity
The result is above linear range.
The sample can be diluted
and rerun, and then the
dilution factor can be
multiplied with the result to
calculate the correct value.
BL – Result is below
linearity
The result is below linear range.
Measuring Chamber Indicators (RBC, PLT, WBC)
Measurement warning –
re-analyze
The cell pulses arrived faster than the analyzer
could process them. Possible reasons might be air
bubbles, electrical disturbances or incomplete
lysing.
Note: Filtered away cell pulses might raise the OR
flag, so it might not be possible to see them in the
histograms or the result parameters. This is a hard
limit determined by the software.
Measurement Statistics
Warning; re-analyze
The rate of cell pulses per time unit varies too
much. Possible reasons might be clogging, air
bubbles, electrical disturbances or difficult to lyse
cells.
Note: Filtered away cells might raise the SE flag,
so it might not be possible to see them in the
histograms or the result parameters.
Mixing Beaker Indicators (RBC, PLT, WBC)
Liquid System Problem –
run prime cycle
The analyzer detected an abnormality during the
emptying of the first dilution from the mixing
beaker. Reasons for flagging might be timeout, or
too short of a transfer time.
Run a “Prime cycle”, before
re-analyzing the sample.
Reagent and Control Indicators (RBC, PLT, WBC, LYM/MID/GRAN)
A control blood was used past its expiry date.
Use a fresh blood control
The reagent was used past its expiry date. Change
to a non-expired lot of reagent.
Use a new lot of reagents
Not enough reagent left,
check reagent levels
The analyzer’s capacity counter has gone below
zero and no reagent is detected. Reason for no
reagent may include empty reagent container or
reagent level sensor not inserted correctly into
reagent container.
Reagent Pipette Indicators (RBC, PLT, WBC)
Diluent system problem
– run prime cycle
The instrument detected an abnormality during one
of the fill cycles of the diluent pipette. Reasons for
flagging might be timeout, short time or bubbles at
the upper detector.
Verify instrument is filled,
run a “Prime cycle” and then
re-analyze sample.
Diluent system problem
– run prime cycle
The instrument detected an abnormality during one
of the empty cycles of the diluent pipette. Reasons
for flagging might be timeout, short time or liquid
not detected at the lower detector.
Lyse system problem –
run prime cycle
The instrument detected an abnormality during the
fill cycle of the lyse pipette. Reasons for flagging
might be timeout, short time or bubbles at the
upper detector.
Lyse system problem –
run prime cycle
The instrument detected an abnormality during the
empty cycle of the lyse pipette. Reasons for
flagging might be timeout, short time or liquid not
detected at the lower detector.
