Operational Messages and Data Flagging
Section 3
Dispersional Data Alerts
These alerts are triggered by the numeric limits entered into the six Patient Limit
Sets (see
for
an explanation) or taken from the instrument’s preset linearity limits. If results for a
parameter exceed these limits, they are flagged on the screen and on the report.
Dispersional alerts are displayed or printed as follows:
Screen display:
Result below lower limit shown in yellow
Result above upper limit shown in purple
Linearity Exceeded: Result displayed as >>>
Graphic Report:
Results outside limits are underlined
Blank Ticket:
Results outside limits are underlined
Preprinted Ticket:
Results outside limits are marked with an asterisk
Specimens with results that exceed the linearity should be diluted with diluent/
sheath according to the laboratory’s procedure and repeated. (Be sure to correct the
results for the dilution factor used.)
NOTE:
MCV, MCH, MCHC and MPV are unaffected by dilution and do not
require correction.
Suspect Parameter Flags
These flags are generated after the instrument evaluates the measured data for a
particular parameter or group of parameters. The result may be suspect due to
interfering substances or the inability of the instrument to measure a particular
parameter due to a sample abnormality.
Introduction to WBC Flagging
There are five WBC parameter flags: WBC, DFLT (NLMEB), DFLT (NE), DFLT
(LM), and DFLT (B). The following WBC population flags may be displayed:
NWBC, FWBC, NRBC, RRBC, BAND, IG, BLAST, VAR LYM. If any of the
WBC population or parameter flags is displayed, the message
SUSPECT
is
displayed under and to the right of the Limits field on the
RUN
and
LABORATORY
WORKSHEET
screens. This message also appears on printouts.
WBC Descriptors
The WBC Descriptors (WOC and NOC) are included on the display screen and
printout to provide additional information about the reported WBC value. If there
is a clinically significant difference between the two results in the QC and Resistant
RBC specimen types, the instrument will select the appropriate result and display
a descriptor in parentheses next to the WBC value.
NOTE:
In the Fragile WBC specimen types, the NOC value is always selected.
