An incompatible blood transfusion occurs when there is a mismatch between the recipient’s blood and the donor’s blood. This mismatch triggers the recipient’s antibodies to attack and destroy the transfused red blood cells, leading to potentially severe consequences such as kidney failure and, in rare cases, even death. However, thanks to meticulous cross-matching of blood in the laboratory, incompatible transfusions are infrequent. The careful matching process ensures compatibility and reduces the risk of adverse reactions, making blood transfusions safer and more effective.
An incompatible blood transfusion is a situation where the patient’s immune system recognizes the donor’s blood as foreign and initiates a reaction against it.
