摘　　要：目的探讨UF-100尿沉渣自动分析仪的临床应用价值及荧光相关指标、尿蛋白对误认RBC、管型的诊断意义。方法用UF-100和尿沉渣镜检分别对320例随机病人的尿标本检测,比较二者对尿液有形成分的检出率,同时对UF-100误认的RBC、管型的荧光相关参数和尿蛋白进行相关分析。结果UF-100和尿沉渣镜检对RBC、管型、小圆上皮细胞的检出有显著性差异,对WBC、酵母菌、结晶检出无显著性差异;UF-100发生误认时,误认RBC的RBC-MFl为(18.68±2.13)ch,与真性RBC-MFl:(15.08±1.28)ch比较差别有显著性,RBC-Fl-DWSD也呈现出与RBC-MFl的一致变化。尿蛋白阳性,管型检出符合率为81.1%。结论尿沉渣成分复杂,UF-100分析只能起筛选作用,其中UF-100的荧光相关指标对RBC误认时判断有重要意义,尿蛋白检测有助于管型诊断,尿沉渣镜检可以提高检验准确性。Objective To evaluate the clinical accuracy of the Sysmex OF- 100 automated urinalysis analyzer. Methods Urinary specimens from 320 patients were analyzed by UF- 100 and reports from microscopic examination of urinary sediments were compared with the parameters of fluorescent light and urinary protein when RBC and pathocast were miscalculated by UF- 100. Results Comparing UF - 100 and the microscopic examination of urinary sediments, the detection rates of red blood cell （RBC）, pathocast, and small round cells （SRC） showed significantly differences, but white blood cell （WBC）, yeast, and crystalline not. When RBC was miscalculated, the non- RBC＇s Mfl was 18.68 ± 2.13ch vs. RBC＇s Mfl 1.5.08 ± 1. 28ch and showed significant difference. There was a significant difference compared to the RBC - MF1, and the same result found in RBC - FI - DWSC. If urinary protein was positive, the detection rate of pathocast was 81.8 % consistent. Conclusions The urinary components are complex. UF 100 can be used just for the screening examination. The fluorescent light parameters of UF - 100 are important to observe when RBC was miscalculated. The urinary protein is helpful in the diagnosis of pathocast＋ The microscopic examination of urinary sediments improves the accuracy of urinary sedimentation evaluation.
