摘　　要：目的探讨UF-50尿沉渣分析仪检测尿液有形成分的干扰因素。方法随机抽取近期部分该院住院患者、门诊患者和体检人员尿液标本共1 200份,利用UF-50尿沉渣分析仪和尿沉渣镜检分别对尿液标本进行测定,对各检测项目的结果进行分析比较。结果 UF-50尿沉渣分析仪能快速、准确地分析多个参数指标,已成为尿液检测标准化的基础,但由于存在许多复杂的干扰因素,部分检测结果会出现假阳性和假阴性。因此,UF-50尿沉渣分析仪可以作为一种有效的过筛工具,但不能代替尿沉渣显微镜检。结论在临床尿液常规检查中,尿沉渣分析仪结合尿沉渣镜检,可以提高检测结果的准确度。Objective To evaluate the influencing factors of the visible components in the urine samples by UF-50 urinalysis analyzer.Methods 1 200 urine samples taken from inpatients,outpatients and examined people were tested with UF-50 urinalysis analyzer and microscopy.The obtained results were comparatively analyzed.Results UF-50 could test multiparameters quickly and accurately as a foundation of urine test standardization.Due to many complicated influencing factors,the partial false-positive（FP） and false-negative（FN） results existed,so that UF-50 could be an effective screening instrument,but which could not replace microscopy.Conclusion Combined use of UF-50 and microscopy can improve the accuracy in routine urine analysis.
