Urine analysis is an essential component of patient assessment, used in screening, diagnosis, and the planning of care. Automated urinalysis systems can save labor and time, and are valuable in high-volume laboratories. The aim of this study was to compare the diagnostic performance of three automated urinalysis systems--Iris iQ200 (AX-4280), the Sysmex UF-1000i (Urisys 2400), and the UriSed LabUMat.
A total of 412 urine samples sent for urinalysis were assessed using all three automated systems.
Correlation between the three instruments, represented as results within one grading unit showed an overall concordance level of more than 80% for chemical urinalysis systems. When we compared microscopy features, red blood cell detection correlation was best between the iQ200 and UriSed instruments (92%). The UF-1000i and iQ200 data on white blood and epithelial cell counts were optimally correlated (86% and 90%, respecttively).
The three automated urinalysis systems demonstrated acceptable correlations in chemical data between instruments. However, whereas the automated microscopy units could be used for initial screening, some manual microscopy was still necessary.
尿液分析是患者评估的重要组成部分，用于筛查、诊断和护理规划。自动尿液分析系统可以节省人力和时间，在大容量实验室中很有价值。本研究的目的是比较三种自动尿液分析系统——Iris iQ200（AX - 4280）、Sysmex UF - 1000i（Urisys 2400）和UriSed LabUMat的诊断性能。
使用所有三种自动系统对总共412份送检尿液分析的样本进行评估。
三种仪器之间的相关性，以一个分级单位内的结果表示，化学尿液分析系统的总体一致性水平超过80%。当我们比较显微镜检查特征时，iQ200和UriSed仪器之间的红细胞检测相关性最佳（92%）。UF - 1000i和iQ200关于白细胞和上皮细胞计数的数据相关性最佳（分别为86%和90%）。
三种自动尿液分析系统在仪器之间的化学数据方面显示出可接受的相关性。然而，虽然自动显微镜检查单元可用于初步筛查，但仍需要一些手动显微镜检查。
