REVIEWING ICT™ CALIBRATION INFORMATION
Calibration of the ICT assays is requested from the RUN OPTIONS
screen using the same procedure described in Module 6, Calibration. The
ICT calibrators are loaded in the Calibrator/Control Carousel in
Positions 40 and 41, and the ICT urine calibrators are loaded in Positions
38 and 39.
When the calibration is complete the calibration information may be
viewed in the ASSAY STATUS and the CALIBRATION SUMMARY
screens.
ASSAY STATUS Screen
The Calibration Information area of the ASSAY STATUS screen of the
Na-S assay is shown below:
Figure 9.2: Calibration Information for Na-S Assay
Most functions and areas of this screen are the same as described in
Module 6, Calibration. The areas that are different are described in the
following table:
• Discuss + and - mV readings
above and below reference
solution mV.
• Cals run in triplicate.
• Slope is the % of ideal
response - change in mV/time
using the Nernst Equation
(flipchart).
• Ideal = A change 61 mV/decade
(Natural log of concentration)
at 37°.
• ICT require calibration every 8
hours.
• SLP Cal Error Code = The slope
of the calibration curve
is < 45%.
