摘要
目的对比分析URIT-1500与AIKELAI AX-4030尿液干化学分析仪检测结果的一致性,选择在参考范围内最适合的尿液干化学分析仪用于尿液的常规检验分析。方法 2015年3月6日至2015年4月6日期间,随机收集西南医科大学附属医院378例新鲜中段尿液标本,在两种尿液干化学分析仪上作平行试验,并采用χ2检验比较各项检出的阳性率,各项目的完全符合率和一般符合率,计算出kappa值。结果两种仪器尿比重(比重)差异百分率均为0.564%(<1%);两种仪器的白细胞、隐血、蛋白质、尿胆红素项目的阳性检出率差异有统计学意义(P<0.05),葡萄糖、亚硝酸盐、酮体、尿胆原项目的阳性检出率差异无统计学意义(P>0.05);白细胞、葡萄糖、亚硝酸盐、酮体、pH一般符合率都>90%,隐血、蛋白质、尿胆原和尿胆红素项目一般符合率在70%以上,除葡萄糖、亚硝酸盐、酮体项目的完全符合率都>90%,其余6项完全符合率都偏低;白细胞、隐血、葡萄糖、酮体、尿胆原、尿胆红素的kappa值>0.40,蛋白质、pH的kappa值>0.30。结论在同一检测条件下,两种仪器检测结果的一致性较差。在同一医院,不能选择两种不同的尿液干化学分析仪,需根据医院的具体情况选择在参考范围之内最适合的仪器,但尿液干化学分析仪只是筛查仪器,还应结合显微镜检查,以满足临床需要。
Objective In order to compare of consistency of results between URIT-1500 and AIKELAI AX-4030 urine drychemistry analyzers and for satisfy the need of urine routine test will choose in the reference range of the optimal urine drychemistry analyzers.Methods During the testing time from March 6,2015 to April 4,2015,random have been collected 378 cleaning midstream urine specimens form Luzhou medical college affiliated hospital were detected by the two kinds of urine drychemistry analyzers in parallel.Positive detection rates of each project were analyzed statistical by chi-square test and counting accordance rate,general accordance rate,and the kappa value completely.Results The percentage of variance difference of specific gravity（SG）between the two analyzers was 0.564%（1%）;Positive detection rates（Pvalue）of WBC,BIL,PRO,BIL between the two analyzers were0.05,the results were statistical significantly;Positive detection rates（Pvalue）of GLU,NIT,KET,URO were0.05;the general accordance rate of LEU,GLU,NIT,KET,pH were90% and BLD,PRO,URO,BIL were70%.Completely accordance rate except GLU,NIT,KET were90% and the rest of six projects trend lower than normal rate.The kappa value of LEU,BLD,GLU,KET,URO,BIL were0.40 and PRO,pH were0.30.Conclusion There is a poor consistency between the two kinds of urine drychemistry analyzers in the same test condition.It can not to use two different kinds of analyzers in same hospital and should choosing the optimal urine drychemistry analyzers in reference range need on the basis of the particular situations of hospital.Urine drychemistry analyzers is used only for screening,and the results should be reviewed by urine sediment microscopy in order to meet clinical needs.
