Warning flags
Warning flags are raised when the analyzer detects
a problem in the analysis process that may cause
incorrect or suspect results or the parameters in the valid blank measurement was too high.
Flag
Meaning
Cause
Action
S
WBC measurement
statistics warning
The distribution of the RBC detection changes in time.
It points to clogging, non-homogeneous sample, cold
sample, partial coagulation of the sample.
Perform cleaning of the ’ELite 5’. Check the
homogeneity, the temperature and the coagulation of
the sample.
Repeat the sample.
s
RBC measurement
statistics warning
The distribution of the RBC detection changes in time.
It points to clogging, non-homogeneous sample, cold
sample, partial coagulation of the sample.
Perform cleaning of the ’ELite 5’. Check the
homogeneity, the temperature and the coagulation of
the sample.
Repeat the sample.
T Blood detector error
Blood Detector malfunction (received signals are all
zeros or not received signals)
Check BD and its connection to the LSDACQ card.
Check sampling tube connection to BD.
u BASO high
The number of the BASO population is high or there
are lyse-resistant cells in the sample.
Repeat the measurement or perform a manual count
on a stained smear.
V WBC vacuum warning
There is a (partial) clogging or leakage in the RBC
part of measurement system. A faulty/ worn-out pump
can create vacuum errors as well.
Perform cleaning of the ’ELite 5’. Perform a self-test.
If vacuum problems persist then call for service.
v RBC vacuum warning
There is a (partial) clogging or leakage in the RBC
part of measurement system. A faulty/ worn-out pump
can create vacuum errors as well.
Perform cleaning of the ’ELite 5’. Perform a self-test.
If vacuum problems persist then call for service.
W Sampling warning
Blood Detector detected a sample volume that was
too small.
Check sample volume in sample vial. Check sampling
process. Re-run sample.
X Differential error
Not enough cells detected during the 4DIFF WBC
differentiating.
Perform a flow cell cleaning procedure! Repeat the
measurement. If the problem persists then ask for
service.
x BASO error
Not enough cells detected during the BASO WBC
differentiating.
If the total-WBC count is below 2 * 103 cells/µl then
perform a manual count on a stained smear.
Perform a flow cell cleaning procedure! Repeat the
measurement. If the problem persists then ask for
service.
Y
Differential percentage
error
Algorithm error while distinguishing the WBC-s in the
4DIFF procedure.
Repeat the measurement. If the problem persists on a
given sample then perform a manual count on a
stained smear.
