RUNNING A TEST
Samples are designated as patient samples by default. If a control is being run, the sample type must be
changed from patient sample to QC Normal or QC Abnormal. If a patient sample is being run, this step is

storage of the control results as patient results in the patient database.
Designating the Sample as a Normal or Abnormal Control
1. Press QC to display the QC SELECTS menu:
Note: A cuvette must be inserted into the instrument to display the QC SELECTS menu. If entry of
a cuvette lot number and/or Operator ID or PIN is required, this must be done before the QC
SELECTS menu can be displayed.
2. Press 1 to designate the sample as a normal control (QC Normal is displayed), or press 2 to
designate the sample as an abnormal control (QC Abnormal is displayed).
Note: The sample type can be designated either before or during the test, unless QC lockout
features are enabled. Once QC is selected, pressing the QC key again briefly displays the QC level
and assay being run.
To exit the QC menu, press the CANCEL key.
Important: Once a QC type is selected, it cannot be changed.
