2.7 HbA1C Control Measurement
2.7.1 Quality Control
Control measurement should be performed at regular intervals to check the status of the instrument and accuracy of
measurement results. Use Canterbury HbA1c control (extendSURE Haemoglobin A1c Lyophilised Controls,
assignment of standard values is based on JCCRM411) or commercially available controls that are specified by your
distributor. For more information, contact your distributor. After changing the measurement mode, always perform
control measurement.
2.7.2 Control Measurement
Prepare: Controls for HbA1c measurement, CONTROL DILUTION SET 80 (RECONSTITUENT 80, DILUENT 80),
sample containers (see step 3), hemolysis control rack (label: H CTRL), barcode labels (when using the internal
barcode reader) and protective gloves
* If sample rack transportation is set to “loop transportation”, the start rack (START) is needed in addition
to the hemolysis control rack.
Wear protective gloves to prevent exposure to pathogenic microbes.
Discard used control and protective gloves in accordance with local regulations for
biohazardous waste.
The typical method for dissolving and diluting controls are explained here. Dissolve and dilute controls as
described in the package insert that comes with the controls.
Carefully read the package insert that comes with the control before use.
Prepare controls with a hemoglobin concentration between 75 mg/dL and 225 mg/dL. Inaccurate
measurement results will be obtained if the control’s hemoglobin level is outside this range.
Be sure to use DILUENT 80 to dilute controls.
Use controls before their expiration dates. Inaccurate measurement results will be obtained if controls are
used beyond their expiration dates. Using expired controls may also seriously degrade the column,
requiring its replacement.
Store controls properly. Inaccurate measurement results will be obtained if controls are not properly stored.
Improperly stored controls may also seriously degrade the column, requiring its replacement.
Use the hemolysis control rack to measure controls.
