Abstract
OBJECTIVE:To analyze the performances of MEK-7222K hematology analyzer(Japan).METHODS:The evaluation was performed on the indices of complete blood cells by using guidelines established in the International Committee for Standard-ization Haematology(ICSH)document.The performances of MEK-7222K hematology analyzer were evaluated from aspects of precision,total repeatability,carry-over rate,linearity,the correlation between the analyzer and microscope in leukocyte differential count,the its correlation to Sysmex XE-2100 in detection results,and the correlation between the mode of whole blood and capillary vessel blood of the instrument.RESULTS:The CV value of within-and between-batch precision and that of the total repeatability were all within the designed range.The carry-over rate was lower than 1%.The linearity was good.The correlation between the instrument and microscope in leukocyte differential count,between the instrument and Sysmex XE-2100 and between the mode of whole blood and capillary vessel blood of the instrument were all satisfactory.CONCLUSION:MEK-7222K automatic hematology analyzer was proved to be accurate and reliable in test results,and the perfomances of the analyzer could all meet the clinical needs,which serves as a choice for large,medium,and small size hospitals in China.
