Introduction Pneumatic tube systems (PTSs) are widely used in many hospitals because
they lead to reduced turnaround times and cost efficiency. However, PTSs may affect the …

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 …

STUDY OBJECTIVES: In this study, blood samples from ED patients that were delivered to
the laboratory by a pneumatic tube delivery system and by a human courier were compared …

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: 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 …

Many studies have explored how using a pneumatic tube system (PTS) is related to the
hemolysis of blood samples, but their conclusions have been inconsistent. This meta …

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 …

OBJECTIVES: To study an episode of excessive sample hemolysis associated with a
recently installed pneumatic tube system from the Accident and Emergency Department …

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: Pneumatic tube system (PTS) is a widely used method of transporting blood
samples in hospitals. The aim of this study was to evaluate the effects of the PTS transport in …
