Specifying QC Lockout Parameters
QC lockout parameters specify the maximum length of time that can elapse before liquid quality control (LQC)
or electronic quality control (EQC) must be successfully run (QC Interval). When the lockout interval has
elapsed and the test cuvette is inserted into the instrument, the user will be prompted to perform the appropriate
QC.
If 911 Limits are enabled, the user will be offered the choice to run a patient test. If this option is selected, the
instrument displays the number (from 0 to 240) of remaining tests per assay that can be run (the 911
override) before QC must be performed (see To Specify QC Exceptions on page 60). Separate requirements can
be specified for the frequency at which EQC and LQC for various tests must be run at normal and abnormal levels.
To Specify Lockout Parameters for All Tests Except EQC:
1.
Click Lock-Out Control on the Configuration Module dialog box (page 53) to display the QC
Lockout dialog box. Select the QC Lock Out Requirements tab (if needed).
2.
Select the test for specifying lockout parameters. Current settings for the test are displayed:
Note: The number of patient tests that have already been run against the 911 override limit is
displayed in the # of 911s Used field when a configuration is read from an instrument. This
value is automatically reset to zero when QC is successfully run.
3.
Enter a check mark in the QC Normal Required box to require QC Normal testing to be run at a
specified interval.
Note: The number of QC Normal tests that have been run and failed is displayed in the #of QC
Tests Failed field.
4.
(If QC Lot Options are not specified) Designate the acceptable range for Normal LQC of the specified
test by entering a value in the Low and High fields.
Note: If Required, Scan only, and/or Pre-stored only is specified for QC Lot Options, the Low
and High fields are not displayed.
5.
Enter a check mark in the QC Abnormal Required box to require QC Abnormal testing to be run at
a specified interval.
Note: The number of QC Abnormal tests that have been run and failed is displayed in the #of QC
Tests Failed field.
6.
(If QC Lot Options are not specified) Designate the acceptable range for Abnormal LQC of the
specified test by entering a value in the Low and High fields.
