Quality Control 91
Additional Operating Instructions
To avoid errors or interruptions during operation, please read the following before using
the Chemistry System.
Switching Process Sequence and System Test List numbers
To avoid having quality control data reported for the wrong tests, do not switch
Process Sequence Numbers
after control results have been accumulated. Patient
results are also affected.
To avoid incorrect reporting of results at the Review and Edit, the Daily QC windows,
and the Print Report form,
you must not modify the order of the test items at the
System Test List window after initial setup. If you reposition any test items at the System
Test List window, results for samples already run could be associated with the wrong test
name.
Loading the reagent trays
CAUTION
Make sure that each reagent container (wedge) is loaded on the correct reagent tray to
avoid erroneous results when using reagent containers without a barcode. Reagent Tray 1
(RTT-1) is the front tray, while Reagent Tray 2 (RTT-2) is the rear tray.
The operator is alerted to this problem by the QC results.
Corrective action is to reload the reagents on the correct trays.
Updating the Cumulative QC
Update the QC Cumulative window before more than 200 daily control samples are run.
The QC Daily Precision Control window can manage a maximum of 200 results for each
control product (level). If an additional control sample is run, the current 200
th
result
(Px200) is overwritten by the new control result. Similarly, if multiple repetitions of a
control are requested, the system aspirates only one sample and its result replaces the
existing 200
th
result (Px200).
To avoid losing control results, you must perform a "QC cumulative save" at the QC
Daily Precision Control window at the end of each day, and perform a New Start when
the system is turned on the next day.
Do not update the QC Cumulative window more than once each day.
If you return to the QC Daily Precision Control window after performing a "QC
cumulative save," you must not perform another update.
Specifically,
you must not select Yes when prompted by "Add daily data to QC
cumulative data." If Yes is selected and there is no daily control data available, the
cumulative data point will be deleted for the day and no additional control data can be
saved for the day.
