Filtration leukapheresis: the influence of granulocyte counts upon the donors' yield
The purpose of this investigation was to determine the influence of granulocyte count on the yield of granulocytes. Healthy adult volunteer donors underwent filtration leukapheresis without premedication. The granulocyte count was measured before and immediately after the procedure. In 73 donors, there was an increase and in 67 donors there was a decrease in the granulocyte counts. In this study of nonmedicated donors those with high initial granulocytes counts and those in which there was a large increase in the postleukapheresis granulocyte counts provided the best yield with the filtration leukapheresis technique.
