Scientists have developed a test called FlowScore, which measures the shape of red blood cells to assess their ability to deliver oxygen. This test could improve specialist transplant and transfusion practices as well as blood banking. Healthy red blood cells have a specific shape that allows for efficient oxygen release, but this shape changes during refrigerated storage, affecting oxygen release. The FlowScore test, developed in collaboration with NHS Blood and Transplant, uses flow cytometry to predict oxygen release from red blood cells. This innovation could help blood banks improve monitoring of stored blood quality and benefit vulnerable patients receiving transfusions.
