Kennedy C, et al. - Herein, platelet function before and after kidney transplantation were characterized using a physiological flow-based assay, developed by researchers, that quantifies platelet function in microlitre volumes of blood under arterial shear. Post-transplant normalization of dynamic platelet function was observed in those with immediate graft function, but not in those with delayed graft function (DGF). There may be important clinical implications, as patients with DGF are more likely to undergo invasive procedures, including transplant biopsies and insertion of central venous catheters.
