Mean (±SE) levels of NTBI, PLI, and CFH and effect of washing in canine stored blood during 6-week storage period. Mean levels of NTBI (IA), PLI (IB), and CFH (IC) sampled from 3 bags of canine universal donor leukoreduced blood are plotted throughout time of storage. (IID-F) mean levels of NTBI, PLI, and CFH, respectively, are represented before and after washing 3 additional bags of 1-week and 6-week stored blood.
