3 Calibration
Calibration overview
When to calibrate
Refer to the ADVIA Chemistry system methods documentation for the calibration and
the reagent blank/rate recommendations.
Setting up the calibration
•
Use the Calibration Setup window to set up calibration for the photometric methods.
•
Absolute and single-point calibration samples are aspirated from the
calibrator/control tray (CTT), while multipoint calibration samples are aspirated from
the sample tray (STT). The blank solution (water) used to run the reagent blanks/rates
is typically assigned to CTT-1.
•
For IgA, IgG, and IgM methods only: Use the Multi-Standards Set Calculator to
determine standard values. Refer to the IgA, IgG, and IgM method sheets for
instructions about setting standard values and calibrator handling and preparation.
NOTE:
If you are running IgA_2, IgG_2, or IgM_2, this does not apply.
•
For multi-point calibration methods, simplified calibration is available after a valid
multi-point calibration is performed.
•
Use the ISE Parameter Settings window to set up calibration for the electrolyte
methods.
ISE Calibration samples are aspirated from the calibrator/control tray (CTT):
serum -
low cal, CTT-11; high cal, CTT-12
urine -
low cal, CTT-13; high cal, CTT-14
Entering absolute or single-point (STD) calibration methods
1. At the Calibration Setup window, in the Proc. Test No. list area, locate the applicable
method.
2. In the Blk posi. Box for the method, enter the cup position for the blank solution on
the calibrator/control tray (CTT).
3. In the STD posi. Box, enter the cup position for the calibrator on the
calibrator/control tray (CTT).
