4.3.1 Calibration Factors
Calibration is performed to ensure the analyzer may deliver accurate sample analysis results.
During the calibration process, a calibrator factor will be calculated. This factor will be used to multiply
with the analysis results to output the final results. When running a calibrator, the analysis results
after being adjusted by the factor should be as close to its assigned targets. Thus the calibrator factor
is derived by below formula:
Calibration with fresh blood includes two modes of "WB" and "PD", which use different fluidic
sequences. Perform calibration for each of the two modes separately.
Besides the calibration factor of the manufacturer, the factor of the users is also used to calculate the
results. For example, under the CBC+DIFF mode, the final analysis results output by the analyzer are
calculated as follow:
Only the 5 traceable parameters are used in the calibration including: WBC, RBC, HGB, MCV and PLT.
When you perform calibration at the service access level, the calibration factors of
manufacturer will be modified, and the calibration factors of user will change to 100.00%.
