2.8 HbA1C Calibration
Calibration provides operation coefficients (calibration coefficients) for correcting measurement results. Use
ARKRAY calibrator (CALIBRATOR 80, assignment of standard values is based on JCCRM411).

2.8.1 Performing Automatic Calibration
When required Description
After installing the instrument Perform HbA1
C calibration before the instrument
is used for the first time after installation.
After replacing the column Measurement errors may occur due to
differences among instruments or changes in
environmental conditions. Perform calibration to
eliminate potential errors.
When restarting the instrument after extended periods of disuse
If HbA1
C control measurement results deviate from control
expected values
If HbA1
C control measurement results obtained after changing
the measurement mode are out of accuracy control range
REFERENCE:
Deviations in control measurement results can be detected by setting <Control expected values> and <Control
error range> to the appropriate values on the [HbA1c measurement setup] screen (see “3.3.5. Setting the HbA1
C
Measurement Conditions” on page 3-13).
Calibration method Description
Automatic calibration Normal calibration method. The instrument measures two HbA1
C standard solutions
(Low and High solutions), and uses the results to automatically determine the calibration
coefficients. Standard values of the standard solutions can be set by:
• Entering numbers using the numeric buttons, or
• Reading the calibration information barcodes during measurement (when using the
internal barcode reader).
User-specified coefficient
setup
Set coefficients “a” and “b” of the HbA1
C correction formula, “Y=aX+b”, using the
numeric buttons.
 Wear protective gloves to prevent exposure to pathogenic microbes.
 Discard used samples and protective gloves in accordance with local regulations for
biohazardous waste.
IMPORTANT:
 Carefully read the package insert that comes with the calibrator before use.
 Use the calibration rack to perform HbA1
C calibration.
