Diatron Abacus 5 - Database Record Management

79
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.

Meaning
Cause
Action
f
BASO blank high
More than 100 cells detected during the ’Baso-blank’ procedure.
Check cleanliness of the reagents and the ‘Abacus 5’. Perform
flow cell cleaning of the ’Abacus 5’. Repeat blank measurement.
See chapter: 6.1.5 :Pneumatics start and blank measurement
Treat BASO result as ‘reduced reliability’.
H
HGB blank high
Last accepted blank result: HGB ≥ 1.0 g/dl
Check cleanliness of the reagents and the ‘Abacus 5’. Perform
cleaning of the ’Abacus 5’. Repeat blank measurement. See
chapter: 7.2.5:Pneumatics start and blank measurement
Treat HGB result as ‘reduced reliability’.
l
PLT URI
The PLT-RBC gap is not clearly detectable on the PLT-RBC
histogram: small MCV, fractured RBC-s, aggregated PLT-s (cold
blood), side-effect of blood-transfusion.
Check the sample quality. Repeat the sample. If the problem
persists then perform a manual count on a stained smear.
M
Out of RBC linearity range
The RBC coincidence is over the limit: too high RBC count.
Check the sample homogeneity. Repeat the sample with manual
pre-dilution.
m
Close to RBC linearity range
The RBC coincidence is close to the limit: too high RBC count.
Treat RBC result as ‘reduced reliability’. Check the sample
homogeneity. Repeat the sample with manual pre-dilution.
O
High linearity range limit
exceeded
If any of RBC, PLT or WBC results are higher than high linearity
range limits.
Perform manual pre-dilution of sample and re-measure it.
o
Low linearity range limit
exceeded
If any of RBC, PLT or WBC results are lower than Low linearity
range limits.
None
p
PLT blank high
Last accepted blank result: PLT ≥ 15 x 10
3
/µl
Check cleanliness of the reagents and the ‘Abacus 5’. Perform
cleaning of the ’Abacus 5’. Repeat blank measurement. See
chapter: 7.2.5:Pneumatics start and blank measurement
Treat PLT result as ‘reduced reliability’.
Q
MON - LYM alert
The MON and LYM populations are not clearly distinguishable on
the scatter-gram.
If other parameters predict a ‘normal’ sample then perform a
cleaning procedure and repeat the measurement.
If MON, MON%, LYM, LYM% 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.
S
WBC measurement
statistics warning
The distribution of the WBC detection changes in time. It points
to clogging, non-homogeneous sample, cold sample, partial
coagulation of the sample.
Perform cleaning of the ’Abacus 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 ’Abacus 5’. Check the homogeneity, the
temperature and the coagulation of the sample.
Repeat the sample.
