目的统计尿液常规检验周转时间(TAT)，分析影响TAT的主要因素，提出改进对策。方法利用医院LIS，对本院2016年1-10月尿常规检验TAT统计分析，建立TAT质量目标值，规定TAT合格率≥90%为达标，计算TAT合格率；于2016年10月17-31日抽取3个病区243份标本手工记录检验前TAT，计算实际住院尿常规检验前TAT合格率。结果门诊尿常规检验总TAT目标值为2小时，合格率为100%；住院尿常规检验前TAT目标值为90min，实验室内TAT目标值为60min，医院LIS统计的检验前TAT合格率为80%左右，手工记录统计的检验前TAT合格率仅为15.63%,实验室内TAT合格率为70%左右。结论门诊尿常规检验总TAT完全合格；住院尿常规检验前和实验室内TAT合格率全<90%,特别是住院尿常规实际检验前TAT合格率极低，是需改进的重点。

Abstract：[Objective]Tostatistical analysis of urine transit time (TAT), analysis of the main factors affecting TAT, put forward improvement measures.[Method]With hospital laboratory information management system (LIS), we statistical analyzed urine (TAT) from January to October2016. Establish turnaround time quality target value.The required turnaround time pass rate of 90% or greater was the standard.The turnaround time pass rate was calculated. 243 inpatients urine samples from October 17 to 31, 2016, from three wards, were collected and the Pre-analytical turnaround timewas recorded, and the pass rate of the actual Pre-analytical turnaround timewere calculated.[Result]Outpatient urine routine test total turnaround time target is 2 hours, with a pass rate of 100%. ThehospitalizedTAT target value is 90 minutes and 60 minutes in laboratory. The TAT pass rate is about 80% with hospital LIS.The qualified rate of TAT before manual inspection is only 15.63, while,laboratory TAT pass rate is about 70%.[Conclusion]Outpatient urineroutine test total turnaround time fully qualified. Inpatient urine routine testpre-analytical turnaround time and Intra-analytical turnaround time pass rate was less than 90%, in particular. The Pre-analytical turnaround time actual pass rate was very low and is need to improve.

根据ISO15189：2012的要求[1]，质量指标是对一组固有特征满足要求的程度的衡量。2015年3月31日国家卫生计生委办公厅印发了《临床检验专业医疗质量控制目标(2015版)》，其中周转时间(TAT)含有2项：检验前周转时间中位数(min)和实验室内周转时间中位数(min)。检验前TAT和实验室内TAT，不同部分(急诊、门诊、住院)、不同专业、不同项目的要求不同，最好分别建立与调查[2]。笔者对本院2016年1-10月份门诊及住院尿液常规检验TAT统计分析，根据自身特点建立质量目标，查找不达标原因，提出对策。
