EVALUATION OF SYSMEX SF-3000 PERFORMANCE CONCERNING INTERPRETIVE MORPHOLOGY FLAGGING OF THE LEUKOCYTE DIFFERENTIAL COUNT

Results from the Sysmex SF-3000 automated haematology analyser are rep orted with special attention to leucocyte morphology Ragging in pathol ogical conditions. Results for leucocyte differential counts provided by the Sysmex SF-3000 were compared with those obtained from the Sysme x NE-8000 and a visual evaluation based on a differential count of 400 leucocytes. One hundred samples from apparently healthy subjects and 100 samples from patients with haematological abnormalities were exami ned, The SF-3000 yielded a rather high frequency of flagging inappropr iately referring to blasts, immature granulocytes, left shift and nucl eated red blood cells/platelet clumps, The presence of atypical lympho cytes was not indicated by appropriate nagging.
