ABSTRACT
Objective To establish the re-examination criteria of the Sysmex XN-9000 automatic blood cell analyzer pipeline suitable for this laboratory for ensuring the accuracy of detection results .Methods A total of 2250 whole blood samples were se-lected from inpatients ,outpatients and subjects undergoing physical examination .The Sysmex XN-9000 blood cell analyzer was a-dopted to conduct the detection .With the manual microscopic examination as the golden standard ,26 items of re-examination criteria were performed the verification and evaluation .The positive predicting value ,negative predicting value ,false positive rate ,false neg-ative rate and re-examination rate were performed by the statistics .Results In compariing the instrument alarm information with the microscopic examination results ,the positive predicting value was 91 .59% ,the negative predicting value was 98 .64% ,the false positive rate was 2 .09% ,the false negative rate was 1 .02% and the re-examination rate was 24 .84% .Conclusion The formulated re-examination criteria of the Sysmex XN-9000 blood cell analyzer is in accord with the characteristics of our laboratory ,which in-creases the detection efficiency ,prevents the missing detection and false detection and has clinical guidance significance .
