Intra-laboratory turnaround time (TAT) is a key indicator of laboratory performance. Improving TAT is a complex task requiring staff education, equipment acquisition, and adequate TAT monitoring. The aim of the present study was to evaluate the intra-laboratory TAT after laboratory automation implementation (June 2013-June 2014) and to compare it to that in the preautomation period (July 2012-May 2013). Intra-laboratory TAT was evaluated both as the mean TAT registered and the percentage of outlier (OP) exams. The mean TAT was 36, 38, and 34 min during the study periods, respectively. These values respected the goal TAT established at 45 min. The OP, calculated at 45 min as well as at 60 min, decreased from 26 to 21 and from 11 to 5, respectively. From a focused analysis on blood count cell, troponin I, and prothrombin (PT) test, TAT improvement was more evident for tests requiring longer preanalytical process. The follow-up of TAT from June 2013 to June 2014 revealed the reduction of the mean TAT as well as of the OP exams after automation implementation and that automation more strongly affects the test in the preanalytical phase including centrifugation of the sample, such as troponin I and PT.
实验室内部周转时间（TAT）是实验室性能的关键指标。改善TAT是一项复杂的任务，需要员工培训、设备购置以及对TAT进行充分监测。本研究的目的是评估实验室自动化实施后（2013年6月至2014年6月）的实验室内部TAT，并将其与自动化实施前时期（2012年7月至2013年5月）进行比较。实验室内部TAT通过记录的平均TAT和异常值（OP）检查的百分比来评估。在研究期间，平均TAT分别为36、38和34分钟。这些值符合设定的45分钟的目标TAT。在45分钟和60分钟计算的OP分别从26降至21和从11降至5。通过对血细胞计数、肌钙蛋白I和凝血酶原（PT）检测的重点分析，对于需要较长分析前过程的检测，TAT的改善更为明显。对2013年6月至2014年6月TAT的随访显示，自动化实施后平均TAT以及OP检查减少，并且自动化对包括样本离心在内的分析前阶段的检测影响更大，如肌钙蛋白I和PT。
