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.
Highlights
To ensure the fastest possible turnaround time in laboratory analysis, the specimens should be delivered to the clinical laboratory quickly and safely
And Objectives This paper aims to study the effects of pneumatic tube system sample transport on complete blood count and coagulation parameters
The present study aims to know the effects of transport of blood samples sent through Swisslog’s Pneumatic tube systems (PTS) compared with hand delivered samples on complete blood count and coagulation using Beckman Coulter LH780 automated analyzer and Sysmex CA 50 semiautomated coagulation analyzer, respectively
Summary
To ensure the fastest possible turnaround time in laboratory analysis, the specimens should be delivered to the clinical laboratory quickly and safely. One such system used for sample transport is pneumatic tube system (PTS). 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. 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. Significant increase in platelet count was observed with PTS samples Further studies on platelet count are warranted to ensure safe transport and accuracy of the results
