摘要
目的通过与显微镜检测、干化学检测进行比较的方法对尿沉渣分析仪UF-50临床应用评价。方法用UF-50检测不同浓度质控物内红细胞、白细胞、管型和细菌,并与理论计算值进行比较的方法评价UF-50准确性和线性。收集109份住院患者尿液标本,分别用UF-50、显微镜检测和干化学方法进行检测,评价3种方法之家的差异和相关性。结果 UF-50检测红细胞、白细胞和细菌的污染携带率分别为0.00344%、0.12%和0.17%。UF-50检测红细胞、白细胞管型和细菌的结果和理论计算结果的回归方程的斜率分别为1.03、0.98、0.75和0.97(P<0.01),呈现非常好的相关性。UF-50检测109份尿液标本结果与显微镜检测结果、干化学检测结果有显著性差异,而UF-50结果与镜检、干化学检测结果存在正相关性。结论结合干化学检测方法和显微镜检测方法 ,UF-50能够为临床诊断和治疗泌尿系统疾病提供快速、可靠依据。
ObjectiveTo evaluate the clinical performance of Sysmex UF-50 automated urinalysis analyzer by comparing UF-50 test results with those of automated dipstick reader and microscopy. MethodsAccuracy and linearity were determined by analyzing different dilutions of quality-control samples.The slope and intercept were measured. A cross-check of UF-50, dipstick and manual microscopy were performed in 109 urine samples.The differences and correlation among them were calculated. ResultsCarryover analysis of UF-50 was 0.00344% for RBC, 0.12% for WBC and 0.17% for bacteria. It suggested that no substantial carryover was determined in all samples. The slope of regression equation was 1.03 for RBC, 0.98 for WBC, 0.75 for cast and 0.97 for bacteria（P〈0.01）. Although the cross-checked results of 109 samples by UF-50 were significantly different compared with those determined by dipstick and manual microscopy, and the significant positive correlation existed between three methods. ConclusionCombinaing with dipstick and manual microscopy, the UF-50 provides a convenient and reliable method for diagnosis and treatment for diseases of urinary system.
