摘　　要：目的评价日立7600-020自动生化仪电解质模块测定钾钠氯离子的精密度、线性和携带率。方法依据美国临床实验室标准化委员会(National Committee for Clinical Laboratory Standards,NCCLS)EP6-A、EP9-A文件方法,计算线性方程和相关系数,并以此为依据进行结果的判断。结果该仪器电解质模块测定精度为结论钾CV批内=0.68%、钠CV批间= 0.53%,氯CV批内=0.51%、钾CV批间=0.96%,钠CV批内=0.66%、氯CV批间=0.85%,且线性方程回归系数r均大于0.999。结论用日立7600-020电解质模块测定样本快速准确,具有测定线性范围广、携带率低的优点。Objective To evaluate the precision, linearity and sample carrying rate of ISE part of Hitachi 7600-020 biochemical analyzer. Method Based on the NCCLS EP6-A EP9-A document, the bias evaluation, correlation coefficient, linear regression equation were calculated. Results The CV value of the same items measured in different analytic system is （0.51-0.68）%, the CV of values between different days is （0.66-0.96）%. The correlation coefficients are more than 0. 999. Conclusion The instrument has the advantages of a good linearity and low sample carrying rate.
