Pneumatic Tube System vs. Manual Transport for Blood Samples in ED
Official title: Pneumatic Tube System Versus Personnel Transport and the Hemolysis Index of Emergency Department Blood Samples: A Randomized, Split-Sample, Single-Blind Trial
Run by Marmara University Pendik Training and Research Hospital · NCT07755007 · Data updated 2026-11-12
This study tests whether using a pneumatic tube system versus manual transport affects how often blood samples from the emergency department show hemolysis.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) presenting to the Marmara University Pendik ED who require routine venous blood draws with two yellow-cap serum separator tubes drawn from the same needle.
✕Probably not a fit
Patients whose samples are not affected by transport method or who do not experience pre-analytical hemolysis may see no benefit.

What this trial studies
In this randomized, single-blind trial, two sequential blood tubes drawn from the same patient are transported by different methods to the lab to compare hemolysis risk. The pneumatically transported sample and the manually carried sample are analyzed at the same time to minimize waiting-time bias. The study uses a block-randomized design to assign which tube goes by each method, and includes adults in an ED setting at Marmara University Pendik Hospital. Hemolysis, diagnostic errors, and pre-analytical variability are the focus, with careful attention to transport mechanics and sample handling. Outcomes include the hemolysis index and potential implications for test accuracy and patient care.
Why it matters
Potential benefit: If successful, the findings could guide ED transport choices to reduce hemolysis-related errors and improve test reliability.
How similar studies have gone: Prior work on transport methods and hemolysis has shown mixed results; this study uses a split-sample design to control for individual variability and may clarify the impact of PTS.
