A blood donation occurs when a person voluntarily has blood drawn and used for transfusions and/or made into biopharmaceutical medications by a process called fractionation (separation of whole blood components). A donation may be of whole blood, or of specific components directly (apheresis).
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 ...
No deferral. No formal ban on blood donation by men who have sex with men exists in Belarus. However, informal restrictions and refusals have occurred, and it is recommended by the Ministry of Health of Belarus that men who have sex with men do not donate blood. Deceased homosexuals are forbidden from having their blood sampled as of 1993.
Allotransplantation. Allotransplant (allo- meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species. [1] The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts.
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...
Donating blood can help some hereditary conditions Hereditary hemochromatosis is a disorder that causes excess iron to build up in the blood. For this condition, donating blood is a benefit.
The Kell antigen system (also known as the Kell–Cellano system) is a human blood group system, that is, a group of antigens on the human red blood cell surface which are important determinants of blood type and are targets for autoimmune or alloimmune diseases which destroy red blood cells. The Kell antigens are K, k, Kpa, Kpb, Jsa and Jsb. [1]
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
