ROCHE URYSIS-2400和AIKELAI AX-4030尿液干化学分析仪检测一致性的比较

Comparison on the consistency between ROCHE URYSIS-2400 and AIKELAI AX-4030 urine drychemistry analyzers

目的比较ROCHE URYSIS-2400尿液干化学分析仪(简称URYSIS-2400)和AIKELAI AX-4030尿液干化学分析仪(简称AX-4030)的检测结果的一致性。方法分别用URYSIS-2400和AX-4030平行测定500例尿液常规标本,比较检测结果的阳性检出率和符合率。随机选取250例使用尿沉渣显微镜复核尿红细胞(ERY)和白细胞(LEU)。通过添加实验评估URYSIS-2400、AX-4030抗维生素C干扰的能力。结果 2台仪器比重(SG)差异百分率均值<1%,其余9项干化学检测项目一般符合率都>90%。URYSIS-2400和AX-4030 ERY项目与尿沉渣显微镜计数的符合率分别为82.4%、84.4%,LEU分别为76.0%和83.2%。URYSIS-2400、AX-4030葡萄糖(GLU)和ERY项目添加维生素C浓度达50 mg/dL时不受干扰。结论 URYSIS-2400和AX-4030检测结果一致性良好,但尿液干化学分析仪只是筛检仪器,还应结合显微镜尿沉渣计数复核的结果以满足临床需要。

Objective To compare the consistency of ROCHE URYSIS-2400 and AIKELAI AX-4030 urine dry-chemistry analyzers.Methods A total of 500 urine specimens were detected by the 2 kinds of urine chemistry analyzers in parallel,and the results were analyzed statistically by positive detection rates and accordance rates.A total of 250 cases were randomly selected for reviewing erythrocytes （ERY）and leulcocytes （LEU）by urine sediment microscopy. Experiments by adding vitamin C were used to evaluate URYSIS-2400 and AX-4030 anti-interference abilities against vitamin C.Results The mean difference percentage of specific gravity （SG）between the 2 analyzers was 〈1%,and all the general consistency rates of the remaining 9 projects were 〉90%.The consistency rates of URYSIS-2400 and AX-4030 were 82.4% and 84.4% with urine sediment microscopy on ERY,and 76.0% and 83.2% on LEU. URYSIS-2400 and AX-4030 anti-interference abilities against vitamin C were up to 50mg/dL on glucose （GLU）and ERY.Conclusions There is a good consistency between the results of URYSIS-2400 and AX-4030,but urine chemistry analyzer is used only for screening,and the results should be reviewed by urine sediment microscopy in order to meet clinical needs.
