“…Firstly, by administering G-CSF-stimulated granulocytes measurable increments in the neutrophil count of up to 4510/ml 1 h following infusion may be achieved, 26,[32][33][34]45,57 and that elevated counts may persist for at least 24 h. 26,34,50,57 The increment achieved with each GTX shows some variability and the factors influencing the increments achieved are not clearly established. Surprisingly, in some studies, there was no clear correlation between the dose of neutrophils administered (either total dose or adjusted per kg body weight) and the subsequent neutrophil increment.…”
