Xenotransfusion uses non-human animals to aid in the shortage of blood for blood transfusion in humans. Some scientists preliminarily favor Sus scrofa domesticus (pigs) as a source of blood after having tested many different animals in order to find the best candidate for a blood donation.
A blood substitute (also called artificial blood or blood surrogate) is a substance used to mimic and fulfill some functions of biological blood. It aims to provide an alternative to blood transfusion , which is transferring blood or blood-based products from one person into another.
Two complex chimpanzee blood group systems, V-A-B-D and R-C-E-F systems, proved to be counterparts of the human MNS and Rh blood group systems, respectively. Two blood group systems have been defined in Old World monkeys: the Drh system of macaques and the Bp system of baboons, both linked by at least one species shared by either of the blood group systems.
Thus far, there are no FDA-approved oxygen-carrying blood substitutes, which is the typical objective of a blood (RBC) transfusion. Non-blood volume expanders are available for cases where only volume restoration is required, but a substance with oxygen-carrying capacity would help doctors and surgeons avoid the risks of disease transmission ...
These anti-human antibodies are produced by plasma cells of non-human animals after immunizing them with human plasma. Additionally, these anti-human antibodies will also bind to human antibodies that may be fixed onto antigens on the surface of red blood cells (RBCs).
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
As of 31 December 2023, a total of 45 [2] human blood group systems are recognized by the International Society of Blood Transfusion (ISBT). [3] The two most important blood group systems are ABO and Rh; they determine someone's blood type (A, B, AB, and O, with + or − denoting RhD status) for suitability in blood transfusion.
An exchange transfusion is a blood transfusion in which the patient's blood or components of it are exchanged with (replaced by) other blood or blood products. [1] The patient's blood is removed and replaced by donated blood or blood components. This exchange transfusion can be performed manually or using a machine . [2]
