摘要
目的探讨尿沉渣定量分析仪联合尿干化学分析仪在尿液细胞检测中的应用价值。方法 500例住院患者,采用sysmex UF-500i、AX4030和离心沉渣镜检对尿液标本进行检测,以沉渣镜检结果为金标准,分析sysmex UF-500i、AX4030在尿液细胞检测中的诊断价值。结果三种检测方法阳性检出率比较差异无统计学意义(P>0.05)。sysmex UF-500i检测白细胞(WBC)的特异度、敏感度和准确度分别为86.96%、80.65%和85.00%;AX4030检测WBC的特异度、敏感度和准确度分别为87.25%、80.00%和85.00%;sysmex UF-500i检测红细胞(RBC)的特异度、敏感度和准确度分别为91.78%、79.59%和88.20%;AX4030检测RBC的特异度、敏感度和准确度分别为92.07%、80.27%和88.60%;sysmex UF-500i+AX4030检测WBC的特异度、敏感度和准确度分别为95.65%、90.32%和94.00%;sysmex UF-500i+AX4030检测RBC的特异度、敏感度和准确度分别为97.17%、93.20%和96.00%。sysmex UF-500i和AX4030联合检测的特异度、敏感度和准确度明显高于单一sysmex UF-500i或AX4030检测,差异有统计学意义(P<0.05)。结论尿沉渣定量分析仪联合尿干化学分析仪在尿液细胞检测中能显著提高特异度、敏感度和准确度,为临床诊断和治疗提供可靠的依据。
Objective To investigate application value by urine sediment quantitative analyzer combined with urine dipsticks analyzer in urinary cells detection. Methods A total of 500 hospitalized patients received sysmex UF-500i, AX4030 and centrifugation sediment microscope examination for urine samples. With sediment microscope examination outcome as the golden standard, analysis was made on diagnostic value by sysmex UF-500i and AX4030 in detection of urinary cells. Results There was no statistically significant significance of positive detection rate in the three detection measures （P〉O.05）. Specificity, sensibility, and accuracy by sysmex UF-500i in detecting white blood cell count （WBC） were 86.96%, 80.65% and 85.00%, which were respectively 87.25%, 80.00% and 85.00% by AX4030. Specificity, sensibility, and accuracy by sysmex UF- 50Oi in detecting red blood cell count （RBC） were 91.78%, 79.59% and 88.20%, which were respectively 92.07%, 80.27% and 88.60% by AX4030. Specificity, sensibility, and accuracy by sysmex UF-5OOi＋AX4030 in detecting WBC were 95.65%, 90.32% and 94.00%. Specificity, sensibility, and accuracy by sysmex UF-50Oi＋AX4030 in detecting RBC were 97.17%, 93.20% and 96.00%. Combined detection by sysmex UF-500i and AX4030 showed obviously higher specificity, sensibility, and accuracy than single detection by sysmex UF-500i or AX4030, and their difference had statistical significance （P〈0.05）. Conclusion Combination of urine sediment quantitative analyzer and urine dipsticks analyzer can remarkably improve specificity, sensibility, and accuracy in urinary cells detection. It can provide creditable reference for clinical diagnosis and treatment.
