Protect product from freezing.
When stored at 2°C to 8°C, unopened ADVIA OPTIpoint (Prod. No. T03-3682-
01), ADVIA SETpoint Calibrator (Prod. No. T03-3685-01), and ADVIA
TESTpoint Reticulocyte Controls (Prod. No. T03-3690-01, Low; and T03-3691-
01, High, respectively) are stable until the last day of the month (expiration date)
printed on the product label, unless otherwise stated.
After being opened, ADVIA OPTIpoint is stable for 7 days, ADVIA TESTpoint
Reticulocyte Controls are stable for 10 days and the ADVIA SETpoint Calibrator
is stable for 5 days, when stored closed in their original containers at 2°C to 8°C.

Gain Adjustment

The gain adjustment procedure is used to adjust the amplification signals in a
channel to properly position the cell signatures within a cytogram.

Calibration

The system must be calibrated for all parameters except %RETIC. Properly
setting the RETIC gain factor provides sufficient accuracy of the %RETIC result
for most laboratories. In such cases, do not change the factory-set %RETIC
calibration factor of 1.00.
However, laboratories using a manual counting method other than those
recommended by NCCLS or ICSH, or laboratories using certain flow cytometric
methods, could observe a significant bias when comparing to the ADVIA
2120/2120i Hematology system method. In this event, use the calibration
procedure to obtain agreement with the other method.
Calibration procedure should be performed:
•
Upon installation of the system.
•
If there is a significant shift in control values after the replacement of a
critical hardware component or reagent lot, after checking gains.
•
Anytime control results and/or moving averages are out of range and it has
been verified that the out-of-control condition is instrument-related.
