Ensuring the rapidity and accuracy of emergency laboratory test results is especially important to save the lives of patients with acute and critical conditions. To better meet the needs of clinicians and patients, detection efficiency can be improved by reducing extra-laboratory sample turnaround times (TATs) through the use of innovative pneumatic tube system (PTS) transport for sample transport. However, concerns remain regarding the potential compromise of sample quality during PTS transit relative to that occurring with manual transportation. This study was performed to evaluate the efficacy of an innovative PTS (Tempus600 PTS) relative to a traditional PTS in terms of sample transit time, sample quality, and the concordance of analytical results with those obtained from manually transported samples.
In total, 30 healthy volunteers aged >18 years were recruited for this study, conducted for five consecutive days. Venous blood samples were collected from six volunteers per day at fixed timepoints. From each volunteer, nine blood samples were collected into tubes with tripotassium ethylene diamine tetraacetic acid anticoagulant, tubes with 3.2 % sodium citrate, and serum tubes with separation gel ( = 3 each) and subjected to all tests conducted in the emergency laboratory in our hospital. 270 blood samples from 30 healthy volunteers were transported and analyzed, yielding 6300 test results. The blood samples were divided randomly into three groups (each containing one tube of each type) and transported to the emergency laboratory manually and with Tempus600 PTS and conventional Swisslog PTS, respectively. The extra-laboratory TATs, sample quality, and test results of the transported blood samples were compared.
The sample quality and test results did not differ according to the delivery method. The TAT was much shorter with the Tempus600 than with the other two transport modes (58.40 ± 1.52 s vs. 1711.20 ± 77.56 s for manual delivery and 146.60 ± 1.82 s for the Swisslog PTS; = 0.002).
Blood sample transport with the Tempus600 PTS significantly reduced the extra-laboratory TAT without compromising sample quality or test result accuracy, thereby improving the efficiency of sample analysis and the services provided to clinicians and patients.
确保急诊实验室检测结果的快速性和准确性对于挽救急危重症患者的生命尤为重要。为了更好地满足临床医生和患者的需求，可以通过使用创新的气动管道系统（PTS）进行样本运输来减少实验室外样本周转时间（TAT），从而提高检测效率。然而，相对于手动运输，人们仍然担心PTS运输过程中样本质量可能会受到影响。本研究旨在评估一种创新的PTS（Tempus600 PTS）相对于传统PTS在样本运输时间、样本质量以及分析结果与手动运输样本结果的一致性方面的效果。
本研究共招募了30名年龄大于18岁的健康志愿者，连续进行5天。每天在固定时间点从6名志愿者采集静脉血样本。从每名志愿者采集9份血液样本，分别置于含有乙二胺四乙酸三钾抗凝剂的试管、含有3.2%柠檬酸钠的试管以及含有分离胶的血清试管中（每种各3份），并在我院急诊实验室进行所有检测。对30名健康志愿者的270份血液样本进行运输和分析，共获得6300个检测结果。将血液样本随机分为三组（每组每种类型各1管），分别通过手动、Tempus600 PTS和传统的瑞士罗氏PTS运输至急诊实验室。比较运输后血液样本的实验室外TAT、样本质量和检测结果。
根据运输方式的不同，样本质量和检测结果并无差异。Tempus600的TAT比其他两种运输方式短得多（手动运输为58.40±1.52秒，瑞士罗氏PTS为146.60±1.82秒，Tempus600为1711.20±77.56秒；P = 0.002）。
使用Tempus600 PTS运输血液样本可显著缩短实验室外TAT，且不影响样本质量或检测结果准确性，从而提高了样本分析效率以及为临床医生和患者提供的服务质量。
