This paper is the first report whether or not pneumatic tube system affects the selection of apheresis donors according to the results of complete blood count. According to the apheresis guidelines, hemoglobin level must be >= 12.5 g/dL and platelet level >= 150/mu L to be a donor. Paired blood samples of 26 healthy volunteers were transported by either hand delivered or a pneumatic tube system to the laboratory. No statistically significant differences were observed in order to mean values of routine complete blood cell count and white cell differential parameters that were send for selection of apheresis donor before the procedure. Therefore, all healthy volunteers decided as a donor according to the laboratory results independent from transport method. (C) 2012 Elsevier Ltd. All rights reserved.
