| 摘 要： | 目的：探讨科室2台血细胞计数仪测定结果的可比性。方法：依据NCCLS EP9-A2文件,每天选取患者新鲜全血标本8份,分别用比较系统Sysmex XT-2000i和实验系统Abbott CD1700这2台血细胞计数仪重复测定标本2次,共测定5 d,应用Excel软件对所测结果进行统计。结果：CD1700与XT-2000i血细胞计数仪测定WBC、RBC、Hb和PLT的相关系数（r）分别为0.997 3、0.998 9、0.997 0和0.998 6,二者的相关性很好（r〉0.975）;对于临床可接受性评价,除了RBC不可接受外,其余3项的预期偏倚均未超过1/2CLIA′88。结论：2台血细胞计数仪测定WBC、Hb和PLT结果一致,但CD1700测定RBC结果的偏倚临床不接受,应采取适当的校正措施。虽然2台仪器均采用原装试剂,检测结果具有溯源性,但为保证其结果的可比性,应进行结果比对和偏倚评估。
