Abstract

Background: Automation helps improve laboratory operational efficiency and reduce the turnaround time. Pneumatic tube systems (PTS) automate specimen transport between the lab and other areas of the hospital. Its effect on complete blood count (CBC) and coagulation is still controversial.

Aim: To study the effects of pneumatic tube system sample transport on complete blood count and coagulation parameters to compare them with hand delivered samples.

Methods: 75 paired samples for complete blood count and 25 paired samples for coagulation analysis were compared between samples sent via pneumatic tube system and hand delivered system.

Results: PTS showed significant decrease in red cell indices such as MCV and RDW and increase in MCHC. Other red cell parameters and WBC parameters showed no statistical significant difference. Statistically significant increase in platelet count was observed with PTS samples. However, these differences were clinically insignificant. No significant effect of PTS was found in PT and APTT samples compared to the hand delivered samples.

Conclusion: Despite statistically significant changes in RBC parameters such as MCV, RDW, and MCHC and platelet count, these changes were clinically insignificant. Hence, blood samples for CBC and coagulation assay can safely be transported via our hospital's PTS. However, further studies on platelet count are warranted to ensure safe transport and accuracy of the results.

气动管道系统输样对常规血液学和凝血试验的影响。

背景:自动化有助于提高实验室的操作效率，减少周转时间。气动管道系统(PTS)自动在实验室和医院其他区域之间进行标本运输。它对全血细胞计数(CBC)和凝血的影响仍有争议。目的:研究气力管道系统送样对全血细胞计数和凝血参数的影响，并与手工送样进行比较。方法:对75例全血细胞计数配对标本和25例凝血分析配对标本进行气力输送和手工输送的比较。结果:PTS可显著降低MCV、RDW等红细胞指标，升高MCHC。其他红细胞参数和白细胞参数差异无统计学意义。PTS样本的血小板计数有统计学意义的增加。然而，这些差异在临床上并不显著。与手工递送的样品相比，PT和APTT样品中没有发现PTS的显著影响。结论:尽管红细胞MCV、RDW、MCHC等参数及血小板计数发生了统计学意义上的变化，但这些变化在临床上并不显著。因此，用于CBC和凝血试验的血液样本可以通过我院PTS安全运输。然而，血小板计数的进一步研究是必要的，以确保安全运输和结果的准确性。
