拜耳ADVIA2400全自动生化分析仪临床应用评价

The evaluation of ADVIA2400 automatic chemical analyzer

目的评价拜耳ADVIA2400全自动生化分析仪的主要性能,探讨仪器在临床中的应用价值。方法使用正常人、患者血清,DADE质控、Bayer质控品和Bayer校正血清,进行重复性试验、准确度试验、样本携带污染率的评价、线性试验、回收试验以及与日立7170A进行相关性试验和t检验。结果各项目在ADVIA2400全自动生化分析仪所进行的试验结果显示该仪器有良好的精密度、准确度,样本携带污染率小(0.17%￣0.68%),线性好,回收率接近100%;与日立7170A全自动生化分析仪测定结果高度相r>关0(.998),没有显著性差异(P>0.05)。结论拜耳ADVIA2400全自动生化分析仪是一台设计合理且性能优良的仪器,适合大批量和速检生化标本的检测。

Objective To evaluate the main performance of Bayer ADVIA2400 automatic chemical analyzer and discuss its value in clinic appliance.Methods Healthy serum,serum of patients,quality-control of DADE,quality-control of Bayer were used to evaluate five parameters like precision,accuracy,linearity,relativity with Hitachi 7170A,nearity and residual contamination of the following tests.Results The assay results showed that the precision,the accuracy and the linearity were good.The residual contamination rate was low（0.17%~0.68%）.Response rate was good and close to 100%.The results are coincident compared with Hitachi 7170A automatic chemical analyzer（r0.998） and without significant difference（P0.05）.Conclusion Bayer ADVIA2400 is a good automatic chemical analyzer and performed well with its design characteristics and suit for large quantities of samples and rapid assay.
