摘要

单样本气动管(PTS)是现代临床实验室常用的快速样本输送系统。然而,它对样本完整性和实验室检测结果的影响仍存在争议。单样本气动输送管的安装和配置在不同的机构都是独一无二的。我们试图通过比较常规化学、免疫学和血液学结果与人工运送的重复样本完整性指数来验证我们的单样本 PTS。2023 年,我们从公司体检中随机抽取了 30 名员工,每人采集了三管促凝血清样本和三管 EDTA 抗凝血样本。A 组使用单个标本 PTS,速度为 8 m/s;B 组使用单个标本 PTS,速度为 15 m/s;C 组使用手动转移。三组样本同时进行了 ALT、AST、TG、TC、LDL、K、NA、CI、TSH、hs-cTnT、NSE、Cyfra21-1 和血液学分析。三组之间的 NSE 和 Cyfra21-1 差异具有统计学意义(P<0.05)。

Validation of a single specimen pneumatic tube system in the clinical laboratory.

The single-specimen pneumatic tube (PTS) is a commonly used rapid specimen delivery system in modern clinical laboratories. However, its impact on sample integrity and laboratory test results remains controversial. The installation and configuration of single-specimen PTS are unique to their institution. We sought to validate our single-specimen PTS by comparing routine chemistry, immunology, and hematology results with a repeat sample integrity index for manual transport. In 2023, 30 employees were randomly selected from the company medical examination, and three tubes of procoagulant serum samples and three tubes of EDTA anticoagulant blood samples were collected from each of them. Group A uses a single specimen PTS at 8 m/s, Group B uses a single specimen PTS at 15 m/s, and Group C uses manual transfer. Specimens from all three groups were simultaneously analysed for ALT, AST, TG, TC, LDL, K, NA, CI, TSH, hs-cTnT, NSE, Cyfra21-1 and haematological analysis. The differences between the three groups of NSE and Cyfra21-1 were statistically significant (P < 0.05). The differences of the rest of the items were not statistically significant. The difference in NSE was not statistically significant between groups A and B (P = 0.401), B and C, and C and A (P < 0.05). The difference in Cyfra21-1 was not statistically significant between groups A and B (P = 0.897), B and C (P = 0.052), and C and A (P = 0.145). Individual sample PTS should be validated for testing prior to use to ensure the results' accuracy.
