10 Calibration
The ‘ELite 5’ analyzer must be calibrated in order to provide correct, reliable results.
Calibration should be done at the following times:
•
At initial installation,
•
After replacing any component critical to the dilution or measurement process,
•
Any time quality control shows a systematic error or is outside predefined limits,
•
At periodic time intervals determined by laboratory regulations.
The ‘ELite 5’ analyzer calibration process consists of running a commercial calibration
material or a human whole blood sample with known parameter values multiple times. The
known parameter values and the average values of multiple runs are used to calculate
calibration factors. The new calibration factors take effect once they are accepted by the
operator.
If you are using a human whole blood as a calibrator, the calibration target values must be
measured on a reference analyzer according to applicable regulations, standards, or
laboratory procedures.
An automated calibration procedure is provided that guides the operator through the
calibration process and performs the calibration factor calculation. Calibration factors can
also be modified directly without running a calibration procedure. Only the parameters that
are traceable to reference methods are calibrated: WBC, RBC, PLT, HGB, MCV and MPV.
To view the calibration functions of the ‘ELite 5’ analyzer, select the ‘Calibration’ icon on the
main menu to display the calibration panel. The Calibration panel displays an option to
calibrate the ‘ELite 5’ analyzer or to view prior calibrations.
