title: Use of a pneumatic tube system for delivery of blood bank products and specimens.
abstract: This study evaluated the effect of pneumatic tube transport on blood bank specimens and products. No important differences were found between aliquots transported in the tube system and those stored in the laboratory as controls. ABO, Rh, antibody detection or identification, direct antiglobulin testing, and elution were studied. Further, no differences in plasma hemoglobin and potassium concentration were found between units of whole blood and packed cells handled in either manner. Platelet counts in platelet concentrates were not decreased and coagulation factor levels in units of fresh-frozen plasma and cryoprecipitate did not decrease after pneumatic transport. The system tested is currently providing expeditious transport of specimens and blood between blood banks and patient care areas.
