目的评价深圳迈瑞BS-200全自动生化分析仪的主要性能。方法选取涵盖各波长的8个项目进行测定,对BS-200全自动生化分析仪进行重复性、线性、精密度、准确度进行评价,并与日立7170全自动生化分析仪进行对比试验。结果日间、批内、批间及总变异系数较小,重复性好,准确度高,线性范围较宽。与日立71710的对比试验,相关系(r)均>0.98。结论该仪器的各评价指标均较好,值得在中小医院推广应用。 Objective To evaluate the main performance of Shenzhen Mindray BS-200 automatic biochemical analyzer. Methods Eight items covering each wavelength were selected for the determination. The repeatability, linearity, precision and accuracy of the BS-200 automatic biochemical analyzer were evaluated and compared with the Hitachi 7170 automatic biochemical analyzer. Results During the day, intra-batch, inter-batch and total variation coefficient were small, with good repeatability, high accuracy and wide linear range. And Hitachi 71710 comparative test, the correlation (r) were> 0.98. Conclusion The evaluation index of the instrument are good, it is worth in the small and medium hospitals to promote the application.
