Dw与URIT-500B尿液干化学分析仪检测一致性的比较

目的 比较并分析dw、URIT-500B检测尿液中10项指标检测结果的一致性。方法 随机选取我院门诊、住院患者晨尿新鲜样本共426例，分别用dw和URIT-500B对尿液中10项干化学项目检测结果进行对比，通过各个项目的阳性检出率、Kappa值、完全符合率和一般符合率评价两种尿液干化学分析仪的检测结果的一致性。结果 Dw和URIT-500B对于比重的差异百分率均值＜1%，pH值的差异百分率均值＜10%；两种仪器的尿胆原和潜血的阳性检出率差异有统计学意义（P＜0.05），胆红素、酮体、蛋白质、亚硝酸盐

Comparison of Consistency between dw and URIT-500B Urine Dry Chemical Analyzer

Objective To compare and analyze the consistency of the results of detection of 10 indicators in urine by dw and URIT-500B. Methods A total of 426 fresh morning urine samples from outpatients and inpatients in our hospital were randomly selected. The results of 10 dry chemical tests in urine were compared with dw and URIT-500B respectively. The positive detection rate and Kappa value of each item were compared. The complete compliance rate and the general coincidence rate were evaluated for consistency of the results of the two urine dry chemical analyzers. Results The mean percentage difference of dw and URIT-500B for specific gravity was <1%, and the mean percentage difference of pH value was <10%. The positive detection rate of urinary bile and occult blood of the two instruments was statistically significant (P<0.05). The positive detection rate of bilirubin, ketone body, protein, nitrite, leukocyte and glucose was not statistically significant (P>0.05); the complete coincidence rate of occult blood was >70%, urinary biliary and bilirubin The complete coincidence rate of ketone, ketone body and white blood cells is >80%, the complete coincidence rate of protein, nitrite and glucose is >90%, and the general coincidence rate of all items except urinary bilirubin is above 90%; Kappa of urinary biliary tract Values >0.40, Kappa values for occult blood >0.50, Kappa values for bilirubin and leukocytes >0.70, ketone bodies, protein, nitrite and glucose >0.80. Conclusion Under the same test conditions, the results of dw and URIT-500B have good consistency. The dw urine dry chemical analyzer meets the clinical needs. The urine dry chemical analyzer is a semi-quantitative screening instrument and should also be combined with a microscope. Screening methods to ensure the reliability of the results.
