Routine utilization
In the followings we summarize the warning flags and give an explanation of their
possible cause and a few hints to overcome the problem:
Uppercase letters refer to WBC or HGB problems:
Flag Meaning
No WBC 3-part differential
E
HGB blank is high, or no
H
HGB blank
B WBC blank is high, or no
WBC blank
WBC clogging
C, Q
Warning flags in lowercase refer to RBC or PLT problems:
Flag Meaning
PLT blank is high, or no
p
PLT blank
RBC blank is high, or no
b
RBC blank
RBC/PLT clogging
c
Warning flags can be grouped according to measurement conditions and according
to the problems relating to the blood sample.
Measurement conditions: when the flags are related to clogging (c, C), probably
hemolysing problems (E, b, B, p) and pressure problems (Fatal pressure error). In
this case we suggest repeating the measurement.
The asterisk flag (*) near a parameter shows some doubt suspected during the
evaluation of that parameter. The reasons can be: a high PLT blank (PLT value will
be marked), a case of indefinite discriminator setting (default location is used for
some reasons, related parameters will be marked), etc.
Another flagging method is evaluation against the normal ranges. If some of the
parameters is out of range it gets a (-) flag if under the range, or gets (+) if over the
range. You can customize ranges for all kind of patients by setting the corresponding
lower and upper ranges. If you set 0 for a range limit, it will be not verified.
5-6
Possible
lymphocytosis.
Repeat the blank measurement. If HGB blank is not stable
there are probably bubbles in the WBC chamber: Run a
cleaning and try blank again. Close the side door if open
during measurement.
Repeat the blank measurement, or run prime lyse and try
blank again.
Possible lyse contamination, or noise problem.
Aperture clogging. Perform cleaning and repeat the
measurement. If it is a general problem, please contact your
Service Personnel.
Low temperature reagents can cause it as well (mainly
diluent), in this case you will have to wait until they reach
room temperature.

Run cleaning and repeat the blank measurement.
Diluent or system cleanliness problem. If it is stable high,
replace the diluent by opening a new tank.
Same action as in case of warning flag p.
The same action as in case of the C warning flag.
