selfblood

Selfblood refers to a person's own blood, typically used in medical contexts for therapeutic purposes. The practice of using one's own blood is known as autologous transfusion or autologous blood therapy. This method is employed to reduce the risk of transfusion reactions, such as allergic responses or the transmission of infectious diseases, as the blood is a perfect match for the recipient.

Autologous blood can be collected and stored prior to scheduled surgical procedures or other treatments where blood loss is anticipated. It can also be collected and reinfused immediately during a procedure, a technique called intraoperative autotransfusion. In some alternative medicine practices, the term selfblood might be used to describe the application of blood for topical treatments or other non-standard therapies, though these applications are not widely recognized by mainstream medical science. The primary medical use of selfblood remains in ensuring compatibility and safety for transfusions.
