The present articleprovides an overview on the significance of autologous red blood cell (RBC) transfusion (ABT) in the hospital and its misuse in sports. Such overview seems timely given several ABT doping scandals. ABTs can avoid harms caused by allogeneic blood transfusions (e.g. blood-borne dise...

ABTs can avoid harms caused by allogeneic blood transfusions (e.g. blood-borne diseases and immunosuppression) and save blood resources.Still, in clinical practice ABT has fallen into disuse.

There are two techniques for RBC storage: refrigeration (cold storage) or freezing (cryopreservation). In the clinical setting, cold-stored RBCs must be re-infused after 42 days, due to increasing storage lesions, whereas cryopreservation allows for storage for up to 30 years.
