Auto-Calibration And Auto-Qc Situations That Need Corrective Steps; Auto Calibration With System-Related Errors; Auto-Calibration With Lot Change; Reagent Pack Switch In Mid-Calibration - Siemens ADVIA 1800 Operator's Manual

Auto-calibration and auto-QC Situations that need corrective steps

For additional information on auto-calibration and auto-QC, refer to the online Operator's
Guide.

Auto calibration with system-related errors

If the system switches to a Backup reagent pack and is scheduled to run a BLK (Blank)
and STD calibration, but there is a system-related error ("s", "t", "S", "r", "F", "A", "M",
"Q" or "G") associated with the STD result, the new BLK and the previous STD will be
used to calculate the calibration curve.
To avoid these system-related errors, load adequate amounts of the BLK and STD
materials in the positions defined in Calibration Setup. If this situation occurs, resolve the
system error and repeat the calibration.

Auto-calibration with lot change

If the system switches to a Backup reagent pack that is from a different lot, and is
scheduled to run only a BLK, the system will use the BLK from the new lot and the STD
value from the old lot to calculate the calibration curve.
If Auto-Calibration with QC is enabled when placing a new lot of reagent on the system
while the current lot is still in use, monitor the Reagent Inventory window and ensure that
a new calibration and QC run is performed on the new lot as soon as it becomes the
Primary pack. Alternatively, pre-calibration of a new lot can be performed prior to its first
use. Review QC values for the new lot before reporting patient results. Repeat the
Calibration and/or QC as needed.

Reagent pack switch in mid-calibration

If the system switches to a Backup reagent pack in the middle of a calibration or QC run,
the software will display a result for the calibration or QC. There is no flag to indicate a
reagent pack switch. However, Reagent Inventory will indicate the use of a new Primary
reagent pack.
If Auto-Calibration with QC is enabled, and a calibration and QC run is coming due,
review Reagent Inventory before reporting patient results to determine if a pack switch has
occurred. If a pack switch has occurred within the calibration, repeat the calibration and/or
QC.
