ANALYZING CELL CONTROLS
8. If any of the control results are outside the expected range, it could be a control problem,
a statistical outlier, or an instrument problem.
a. Review the logic outlined under Heading 4.3, INTERPRETING AND USING CELL
CONTROL DATA in this Training Guide to correct the problem.
b. This information is also covered in
Reviewing Control Results under Heading 7.3
RUNNING CELL CONTROLS
, in the Online Help System or the Instructions for Use
manual.
9. When the control is out of range, the QC alarm is triggered.
a. When the QC alarm is triggered, flashes and a QC Failed message is posted on
the Alarm screen.
b. You can elect to have the instrument stop analyzing patient samples when a QC
alarm is triggered.
1) Selecting Auto-Stop for a QC Failed message is covered under Heading 3.1,
MISCELLANEOUS (OPERATIONAL) SETUP OPTIONS, in this Training
Guide.
2) Click tt tt
General tab to see the current setting for this option.
c. You can elect to have the instrument display (and print) a QC Failed message in the
tree view for the control that exceeded its limits and for any patient sample ran
following that control.
1) Selecting the display of a QC Failed message in the tree view (
Display and Print
“QC Failed” message
) is covered under Heading 3.1, MISCELLANEOUS
(OPERATIONAL) SETUP OPTIONS, in this Training Guide.
2) Click tt tt
General tab to see the current setting for this option.
3) Once triggered, the QC Failed message is displayed in the tree view of all
patient samples until one of the following occurs:
a) A QC analysis of the same control lot is ran and is within limits.
b) All the QC data for the control lot that triggered the message is deleted.
10. The Operator may decide to exclude an analysis.
a. Control results should only be excluded immediately if you can trace the
unacceptable results to an Operator error.
b. Excluding too many runs can cover up an instrument problem and bias results.
11. Have the trainee run controls in the Manual mode, using the
Running Cell Controls: Manual
(Stat) Mod
e procedure under Heading 7.3 RUNNING CELL CONTROLS, in the Online Help
System or the Instructions for Use manual.
12. Give the trainee a copy of the
CONTROL ANALYSIS SUMMARY from this Training Guide and
review the procedures.
