The Establishment and Application of Quality Control System on Sysmex-XN Series Automatic Blood Cell Analyzer

ObjectiveTo establish a comprehensive, appropriate quality control system on the Sysmex-XN series automatic blood cell analyzer to improve the reliability of blood cell count results. MethodsRoutine quality control was carried out every day, using high, normal and low levels of fresh whole blood controls offered by Sysmex. The results from the Sysmex online quality control was got timely. We monitored the variation of mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) with the moving average method real-timely, and quality control was performed for fresh whole blood samples of patients once every two hours. ResultsEverything was under control, and the moving average was within the permitted range. ConclusionThe reliability of laboratory blood cell count results can be effectively improved by using this quality control system effectively and comprehensively on the Sysmex-XN automatic blood cell analyzer.

應用Spife Combo電泳儀進行血紅蛋白電泳的質量保證及特殊故障分析

不同廠商紫頭真空采血管的血常規結果比對

目的：對不同廠商的紫頭真空采血管進行評估，其血常規結果是否有差異。方法：同時使用美國BD公司和成都瑞琦公司生產的紫頭真空采血管采集40份新鮮全血標本，分別在自動血液分析儀XE-2100進行檢測，再進行白細胞(WBC)、紅細胞(RBC)、血紅蛋白(HGB)、血小板(PLT)等參數的相關性比較。結果：WBC、RBC、HGB和PLT等參數的差異百分率分別為：0.49%、0.05%、0.13%和1.01%；相關系數(r)分別是：0.9985、0.9964、0.9966和0.9932；t檢驗的P值分別是：0.9706、0.9020、0.9679、0.9061，均gt;0.05。結論：真空采血管普遍應用于臨床標本的采集，由于真空度、抗凝劑的量、管壁的質量對血常規結果均有影響，不同廠商的真空采血管質量不完全相同，通過新鮮全血的結果比對，美國BD公司和成都瑞琦公司生產的紫頭真空采血管的血常規結果相關性好，其相關系數均在0.99以上，P值均gt;0.05，無顯著性差異，差異百分率小，均lt;±2.0%的可接受范圍，表明可用于臨床。
