新鲜抗凝全血对Sysmex不同型号血细胞分析仪比对评价

目的：用新鲜抗凝全血在不同型号的血细胞分析仪上测定，各项参数与参考仪器比较，校对检测仪器使得同一份样本在不同型号仪器上测定结果的一致性。方法用参加室间质评结果满意的 Sysmex XE-2100作为参考比对仪器，各仪器性能评价合格后，用不同浓度的抗凝全血在Sysmex XS-800i，Sysmex XT-4000i和Sysmex XT-1800i上进行测定，最后用Sysmex XE-2100测定结果作为靶值，分别与其它仪器的测定结果进行比对。结果 XS-800i与比对仪器 Sysmex-2100的偏倚：WBC 2.85％，RBC 1.44％，HGB 0.75％，HCT 2.11％和PLT 5.53％；XT4000i与比对仪器 Sysmex-2100的偏倚：WBC 1.26％，RBC 0.95％，HGB 0.68％，HCT 1.35％和 PLT 2.68％；XT-1800i与比对仪器 Sysmex-2100的偏倚：WBC 5.21％，RBC 1.96％，HGB 1.60％，HCT 1.96％和 PLT 4.95％，XT4000i，四台血细胞分析仪 WBC，RBC，HGB，HCT， MCV和PLT各项参数的偏倚都在允许范围。结论当实验室有多台血细胞分析仪时，应定期对血细胞分析仪保养维护并定期做好各仪器间比对，及时发现问题校准仪器，确保各仪器间测定结果的一致性，提高检测结果的准确性。

Evaluation of Sysmex Hematology Analyzers with Fresh Blood

Objective To investigate comparability between Sysmex different hematology analyzers.The consistency of all he-matology analyzers with the same fresh sample.Methods Selected Sysmex XE-2100 as reference instrument which attend external quality assessment.Fresh high,medium and low blood were detected in Sysmex XS-800i,Sysmex XT-4000i and Sys-mex XT-1800i,compared results of WBC,RBC,HGB,HCT,MCV and PLT.Results The bias of XS-800i and XE-2100 was WBC 2.85%,RBC 1.44%,HGB 0.75%,HCT 2.11% and PLT 5.53%.The bias of XT-4000i and XE-2100 was WBC 1.26%,RBC 0.95%,HGB 0.68%,HCT 1.35% and PLT 2.68%.The bias of XT-1800i and XE-2100 was WBC 5.21%, RBC 1.96%,HGB 1.60%,HCT 1.96% and PLT 4.95%.It had good compatability.All various parameters was in the al-lowed range.Conclusion Should maintenance and compare the hematology analyzers periodically,found the problem then calibration instruments in time,ensure the consistency of measurement results between different instruments and guarantee accuracy of the results.
