最近,一些制造商推出了自动化尿液分析平台。本研究旨在比较UF-5000 (Sysmex Corporation,神户,日本)和cobas®u 701 (Roche Diagnostics, Rotkreuz,瑞士)尿液沉积物分析仪与作为参考方法的手动相差显微镜显微镜诊断性能。

在两个自动化平台上共对195份尿液样本进行了分析,并进行了手工显微镜检查。协议通过Cohen的kappa(κ)分析评估了协议,并计算敏感性和特异性。

对于红细胞(RBC)和白细胞(WBC),肾小管上皮细胞,透明管,细菌(BACT)和酵母菌(YLC),UF-5000与手动显微镜的一致性几乎一样(κ> 0.8) 鳞状上皮细胞(SEC)和病理模型的转化率为(κ= 0.61-0.80),过渡上皮细胞的转化率为中度(κ= 0.41-0.60)。 cobas®u 701对WBC表现出基本一致性(κ= 0.61-0.80),对于透明石膏的中度一致性(κ= 0.41-0.60),对于RBC,SEC和非鳞状上皮细胞的公平一致(κ= 0.21-0.40) (NEC),病理类型,BACT和YLC。UF-5000对RBC的敏感性为98.5%,对病理铸型的敏感性为83.3%。cobas®u 701对WBC的敏感性为83.0%,对YLC的敏感性为31.6%。

与cobas®u 701 (Roche)模块相比,UF-5000 (Sysmex)分析仪与人工相差显微镜显示出更好的诊断一致性。Sysmex平台的尿沉渣分析结果可靠。然而,病理样本应经过手动显微镜验证。
