Abstract

Objective To calibrate hematology analyzers with fresh blood to make their parameters comparable. Methods Fresh blood assigned by hematology analyzer Sysmex XT-1800i as normative measurement system was used to calibrate two Sysmex KX-21 analyzers and one KX-21N analyzer respectively.Results In the parameters calibrated for hematology analyzers,there was about 53.3%(8/15) over allowable bias before calibration but 13.3%(2/15) after calibration with fresh blood.Conclusions Parameters of hematology analyzers calibrated with fresh blood are comparable and coincident.
