Washing red blood cell (RBC) units prior to transfusion is indicated for certain patients. In the United States, units stored at 1°C–6°C or transported at 1°C–10°C are available for issue up to 24 h, if not used immediately. The washing procedure commonly utilizes room temperature saline resulting in units starting out above the allowed temperature range. This leads to wastage if units are issued and returned too quickly before having a chance to equilibrate in a transport cooler.
