Evaluation of a pneumatic-tube system for delivery of blood specimens to the blood bank.
This study evaluated the suitability of delivering patient blood specimens to the blood bank by a hospital pneumatic-tube system. No significant discrepancies were found between duplicate pneumatic-tube and hand-carried specimens in ABO and Rh typing, Du and direct Coombs' testing, rouleaux formation, and antibody screening and identification. ⋯ Our pneumatic-tube system may be safely used to transport patient blood specimens for routine type and crossmatch. Slight hemolysis in some pneumatic-tube specimens makes our pneumatic-tube system unsuitable for transporting blood specimens collected for evaluation of transfusion reactions.
