Abstract:
Objective To establish and evaluate the review criteria of blood routine detection by the Sysmex XE‐5000 hematolo‐gy analyzer in our hospital for improving the effectiveness of the measurement results .Methods 606 blood samples were collected from the outpatients and inpatients during 2014 and performed the microscopic examination by 2 technologists‐in‐charge with the double‐blind method .The average value of these results was used as the judging criteria .According to the 41 items of rule formula‐ted by the international expert group and combining with the patients characteristics of infectious disease hospital and instrument features in this hospital ,20 items of review criteria for blood routine test of our hospital was formulated .Results With the micro‐scopic examination results as the criteria ,among 606 detected samples ,116 samples were in line with the rules and the review rate was 19 .14(116/606) ,in which the true positive rate was 6 .93% (42/606) ,the false positive rate was 12 .21% (74/606) ,the false negative rate was 2 .64% (16/606) ,the true negative rate was 78 .22% (474/606) ,the sensitivity was 72 .41% and the specificity was 86 .5% .The expected values of positive and negative results were 36 .21% and 96 .73% respectively .The total effective rate was 85 .15% .Conclusion The review criteria formulated by this laboratory are reasonable and effective ,which has an important significance in the clinical application for increasing the detection speed of blood routine ,improving the laboratory reports quality , without missed true blood patients and accurately providing the valuable information for clinicians .
