Abstract:
Objective To set up a calibration system for automated hematology analyzers with fresh blood in clinical laboratory.Methods Fresh blood assigned by a traceable measurement system was used to calibrate nine hematology analyzers, and compared the bias before and after calibration.Results In the parameters to be calibrated for the hematology analyzers, there was about 55.6% (25/45) over allowable bias before calibration but 15.6% (7/45) after calibration with fresh blood. Among the results of bias over allowable upper limit were mostly existed in 3-part differential hematology analyzers, and mainly focused on WBC and PLT.Conclusion It is available to calibrate different hematology analyzers with fresh blood in a clinical laboratory.
