摘要
目的探讨尿沉渣分析仪联合尿液干化学法对尿液白细胞检测的价值。方法收集2019年1~6月江西省宜春市第三人民医院检验科的500例尿液标本,依据随机双盲法分为对照组(n=250)与观察组(n=250)。对照组采用尿液干化学法,观察组采用尿沉渣分析仪联合尿液干化学法。以尿沉渣镜检为金标准,比较两组尿液标本尿液白细胞检出的阳性率、漏诊率、误诊率。结果尿沉渣镜检结果显示,对照组尿液标本的尿液白细胞阳性率为79.20%(198/250),观察组尿液标本的尿液白细胞阳性率为77.60%(194/250)。两组的尿液白细胞阳性率比较,差异无统计学意义(P>0.05)。观察组检测方法检测尿液白细胞的阳性率为76.00%(190/250),高于对照组的56.00%(140/250),差异有统计学意义(P=0.035)。观察组尿液标本的尿液白细胞检出符合率高于对照组,检测漏诊率、误诊率均低于对照组,差异有统计学意义(P<0.05)。结论尿沉渣分析仪联合尿液干化学法可降低尿液白细胞检测的漏诊率、误诊率,提高检测价值。
Objective To explore the value of urine sediment analyzer combined with urine dry chemistry method for urine white blood cell detection.Methods A total of 500 cases of urine specimens from the Third People′s Hospital of Yichun City in Jiangxi Province from January to June 2019 were collected and divided into the control group(n=250)and the observation group(n=250)according to the randomized double-blind method.Urine dry chemical method was used in the control group,and urine sediment analyzer combined with urine dry chemical method was used in the observation group.Urine sediment microscopic examination was used as gold standard,the positive rate,missed diagnosis rate and misdiagnosis rate of urine leucocytes were compared between the two groups.Results The results of urine sediment microscopy showed that the urine leukocyte positive rate of the control group was 79.20%(198/250),and the urine leukocyte positive rate of the observation group was 77.60%(194/250).There was no significant difference in the positive rate of urine leukocytes between the two groups(P>0.05).The positive rate of urine leucocytes detected by the test method in the observation group was 76.00%(190/250),which was higher than that in the control group(56.00%)(140/250),and the difference was statistically significant(P<0.05).The coincidence rate of urine white blood cells detected in the urine samples of the observation group was higher than that of the control group,and the missed diagnosis rate and misdiagnosis rate in the urine samples of the observation group were lower than those of the control group,and the differences were statistically significant(P<0.05).Conclusion Urine sediment analyzer combined with urine dry chemistry method can reduce the missed diagnosis rate and misdiagnosis rate of urine leukocyte detection,and improve the detection value.
