leukodepletion

Leukodepletion is a process that removes white blood cells (leukocytes) from blood donations or transfusions. White blood cells can cause immune reactions or transmit infections, so reducing them helps improve safety. The process typically involves passing blood through a filter that traps the white cells while letting other components, like red cells and plasma, pass through. This technique is especially important in hospital settings to decrease the risk of febrile reactions and other complications for recipients, making transfusions safer and better tolerated.
