目的 评价不同检测系统血小板(PLT)计数结果的偏差及临床可接受范围.方法 根据美国临床实验室标准化委员会(NCCLS)EP-9A2文件要求.每天选取8例标本,分别在3个检测系统上进行PLT测定,共测定8 d,记录结果.对所测结果进行统计分析,计算和评价其系统间的偏差.以Beckman Coulter LH 750 System为比较检测系统,Sysmex XT-1800i和Coulter Ac.T5 diff为实验检测系统进行方法学比较,计算相对偏差,以1/3 CLIA'88规定的允许误差为标准进行评估.结果 Coulter LH 750 System与XT-1800i的相关系数(r)=0.999,回归方程为Y=0.995X-2.209;Coulter LH 750 System与Coulter Ae.T 5diff的r=0.997,回归方程为Y=1.006X-1.108.结论 3种系统检测PLT的偏差在临床可接受范围内,结果具有可比性.
目的 評價不同檢測繫統血小闆(PLT)計數結果的偏差及臨床可接受範圍.方法 根據美國臨床實驗室標準化委員會(NCCLS)EP-9A2文件要求.每天選取8例標本,分彆在3箇檢測繫統上進行PLT測定,共測定8 d,記錄結果.對所測結果進行統計分析,計算和評價其繫統間的偏差.以Beckman Coulter LH 750 System為比較檢測繫統,Sysmex XT-1800i和Coulter Ac.T5 diff為實驗檢測繫統進行方法學比較,計算相對偏差,以1/3 CLIA'88規定的允許誤差為標準進行評估.結果 Coulter LH 750 System與XT-1800i的相關繫數(r)=0.999,迴歸方程為Y=0.995X-2.209;Coulter LH 750 System與Coulter Ae.T 5diff的r=0.997,迴歸方程為Y=1.006X-1.108.結論 3種繫統檢測PLT的偏差在臨床可接受範圍內,結果具有可比性.

Objective To evaluate bias and clinical acceptability of platelet results among different detection systems.Methods According to the profile of NCCLS EP-9A2 document,8 samples were chosen to test platelet count on 3 equipments for 8 days.Results were analyzed and the bais among three equipments was evaluated.Coulter RLH 750 System was set as the comparison system,while Sysmex XT-1800i and Coulter Ac.T5 diff were set as the laboratory systems.Relative bias was computed by medical decision level of platelet.With 1/3 CLIA'88 permissive error the biases of the tWO laboratory systems as the standard were evaluated.Results The correlation coefficient of LH 750System and Sysmex XT-1800 was 0.999,and the regression equation was Y=0.995X-2.209;the correlation coefficient of LH 750 System and Ac.T5 diff was 0.997,the regression equation was Y=1.006X-1.108.Condnsion The biases of platelet count among three equipments are in the clinical acceptable range and the result comparibility among them is exist.
