Changes in clotting time in relation to storage duration of 12 red blood cell (RBC) concentrates in the STA®-Procoag-PPL assay.
Twelve RBC concentrates were analysed at 13 time-points during storage for a total of 42 days. There was a steady decrease of the clotting time during storage. A shorter clotting time reflects more important procoagulant activity. In the figure, boxes include from the first to the third quartile and whiskers indicate maximum and minimum values.
