Webb14 apr. 2024 · As a result, the Australian Blood Authority's guidelines recommend an RBC transfusion to a patient at an Hb concentration of less than 70 g/L, while a transfusion at a Hb between 70 and 90 g/L should be based on the need to relieve clinical signs and symptoms of anaemia. However, this range is broad, and many studies in the general … Erythrocyte fragility refers to the propensity of erythrocytes (red blood cells, RBC) to hemolyse (rupture) under stress. It can be thought of as the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to stress (typically physical stress, and most commonly osmotic and/or mechanical stress). Depending on the application as well as the kind of fragility involved, the amount of stress applied and/or the significance of the resultant hemolysi…
