UF-100尿沉渣分析仪和显微镜检测尿液中有形成分的比较

Comparison of Examining the Visible Component in Urine between Sysmex UF-100 Automated Urinalysis Analyzer and Microscope.

目的探讨UF-100尿沉渣分析仪与显微镜检测尿液有形成分的结果符合情况及影响因素。方法应用配对分析法将同一标本同时用UF-100尿沉渣方法和显微镜检测尿液中有形成分,对结果进行对比分析。结果UF-100检测红细胞、白细胞、管型、小圆上皮细胞的结果普遍偏高和假阳性。结论UF-100尿沉渣分析仪检测结果受诸多因素影响,表现为检测结果偏高和假阳性。应用UF-100仪器检测结果阳性时必须用显微镜计数法复检进一步确认后,方可向临床发出最终确诊报告。

Objective To understand the coincident conditions and inferencing factors about examining the shaped components between sysmex UF-100 automated urinalysis analyzer and microscope. Methods Applied matching analyse method to detect and measure the shaped components for all urine samples using direct microscope enumerative method and apparatus, then analysed the consistency of these results. Results The amount of red blood cells （ RBC ） ,white blood cells （ WBC ）,pipe models and small round cells （SRC） are usually higher and misjudge when using UF-lOO.Conclusion The amounts of UF-100 are usually higher than that of actual results and have false positive. Before delivering the diagnosis report to the clinic, the results from UF-100 should be checked by microscope enumerative method.
