Bath time for blood cells: improving the red blood cell washing process

What is this research about?

From the time of donation until transfusion, red blood cells can be stored for up to 42 days. During this time, the cells must be kept alive and functioning. Red blood cells are stored in solutions that contain nutrients and in bags that allow exchange of oxygen and other gasses. The cell’s metabolism – the chemical processes that sustain life – remain active in stored red blood cells. The chemicals that result from metabolism (metabolites), are released by the cells and can build up in the bag over time. These metabolites, and other proteins that are in the bag, are transfused along with the red blood cells
