9. Troubleshooting and System Messages
Sample Pathology Messages and Flag Indicators
LF Lyse system problem The analyzer detected an abnormality during the
ll cycle of the lyse pipette. Reasons for agging
might be timeout, short time or bubbles at the
upper detector.
Verify analyzer is
lled, run a Prime
Cycle and then
re-analyze sample.
LP Lyse system problem The analyzer detected an abnormality during
the empty cycle of the lyse pipette. Reasons for
agging might be timeout, short time or liquid not
detected at the lower detector.
ST Air bubbles The time for the liquid meniscus to pass from the
lower to the upper detector is unreasonably short.
Run a Prime Cycle,
before re-analyzing
the sample.
TB Air bubbles Air bubbles were detected by the start detector in
the diluent column.
TL Possible orice blockage The liquid meniscus in the measuring tube never
passed the lower detector.
TU Possible orice blockage The liquid meniscus in the measuring tube passed
the lower detector but never passed the upper one.
EF EOS reagent pipette Fill
error (EOSa)
The analyzer detected an abnormality during the
ll cycle of the EOS reagent pipette. Reasons for
agging might be timeout, short time or bubbles
at the upper detector.
Verify analyzer is
lled, run a “Prime
cycle” and then
re-analyze sample.
EP EOS reagent pipette
Emptying error (EOSa)
The analyzer detected an abnormality during the
empty cycle of the EOS reagent pipette. Reasons
for agging might be timeout, short time or liquid
not detected at the lower detector.
WBC Dierential Abnormalities (LYM, MON, GRA/NEU, EOS)
Indicator Message Description Action
BD High interference between
populations.
The calculated populations for LYM, MON, GRA
overlap too much. Often in pathological samples
with granulocytosis or lymphocytosis.
Blood sample too
old or pathological
sample. Re-analyze
sample, if still
agged an alternative
methodology such as
e.g. slide review, is
adviced.
NM No WBC population found There was no mode in the WBC distribution
between the LYM-L and GRA-H settings.
LM
MM
GM
Only one WBC population
found
There was only one mode in the WBC
distribution between the LYM-L and GRA-H
settings. Often in pathological samples with
granulocytosis or lymphocytosis.
TM Too many WBC
populations found
There were more than two modes in the WBC
distribution between the LYM-L and GRA-H
settings.
LW Low WBC Flag If the WBC total is < 3.0 10
9
/l or if the 4-part
dierential failed (more EOS particles are
counted than WBC or GRA).
