Which term refers to a blood transfusion donated by the patient for their own use?

The term that refers to a blood transfusion donated by the patient for their own use is autologous transfusion. This type of transfusion is beneficial for patients who may need a blood transfusion during surgery or due to a medical condition, as it reduces the risk of transfusion reactions and infections. By using their own blood, patients can ensure compatibility and avoid complications associated with donor blood.

In contrast, allogeneic transfusion refers to blood transfusions obtained from a volunteer donor, while homologous transfusion is often used interchangeably with allogeneic transfusion to signify that the blood comes from another individual. A transfusion reaction is an adverse response that can occur during or after a blood transfusion, typically related to incompatible blood types, but does not pertain to the source of the transfused blood itself.
