Background: The objective of the study was to find the incidence of hemolysis in samples
transported through a pneumatic tube system (PTS) at different speeds. Methods: This …

Background We evaluated the effects of pneumatic tube system (PTS) transport rates and
distances on routine hematology and coagulation analysis. PTS effects on centrifuged blood …

Background Modern pneumatic transportation systems (PTSs) are widely used in hospitals
for rapid blood sample transportation. The use of PTS may affect sample integrity. Impact on …

Pneumatic tube system (PTS) transport has been described as a source of in vitro
hemolysis. The causes include irregular forces generated by the vacuum system, sudden …

BACKGROUND Pneumatic tube systems (PTSs) for the transport of blood samples are
regaining popularity in medical centers after earlier reports that their use could introduce …

Background: The pneumatic tube system (PTS) has been implicated in inducing haemolysis.
It is not known whether certain sample types are more susceptible to haemolysis than …

Background Pre-analytic mechanical hemolysis of blood samples can lead to inaccurate
laboratory results and delays in patient care. Hemolysis may result in spuriously elevated …

Introduction The pneumatic tube system (PTS) is an automated and fast modality of
transportation of biological samples, but it has been reported to induce preanalytical errors …

Methods The hemolysis index is measured on all samples submitted for potassium analysis.
We queried our hospital laboratory database system (SunQuest®) for potassium results for …

Objective: The frequency of hemolysis of blood samples may be increased by transport in a
pneumatic tube system. The purpose of this study was to evaluate the effect of pneumatic …
