Purpose of Paper
The purpose of this paper was to determine the effects of pneumatic tube system (PTS) transport and transport speed on indicators of hemolysis in blood specimens.
Conclusion of Paper
PTS transport at high speed (3 m/s) for 115 m resulted in increased lactate dehydrogenase (LD), and high speed transport for 225 m resulted in increased hemoglobin, potassium (K) and LD compared to hand-delivery, indicating high speed PTS transport induced hemolysis. PTS transport at low speed (2 m/s) for 115 m did not affect LD, K or hemoglobin compared to specimens that were hand-delivered.

Study Purpose
The purpose of this study was to determine the effects of PTS transport and transport speed on levels of the hemolysis indicators LD, K and hemoglobin in blood specimens. Specimens were collected and transported in red-cap serum tubes.
Summary of Findings:
PTS transport at high speed (3 m/s) for 115 m resulted in increased LD, and high speed PTS transport for 225 m resulted in increased hemoglobin, K and LD compared to hand-delivery, indicating high speed PTS transport induced hemolysis. PTS transport at low speed (2 m/s) for 115 m did not affect LD, K or hemoglobin compared to specimens that were hand-delivered.
