  2. ABO blood group system - Wikipedia

    en.wikipedia.org/wiki/ABO_blood_group_system

    ABO(H) blood group antigens are also carried by other hemostatically relevant glycoproteins, such as platelet glycoprotein Ibα, which is a ligand for vWF on platelets. [57] The significance of ABO(H) antigen expression on these other hemostatic glycoproteins is not fully defined, but may also be relevant for bleeding and thrombosis.

  3. Blood compatibility testing - Wikipedia

    en.wikipedia.org/wiki/Blood_compatibility_testing

    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.

  4. Blood type - Wikipedia

    en.wikipedia.org/wiki/Blood_type

    Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also known as a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs).

  5. Human blood group systems - Wikipedia

    en.wikipedia.org/wiki/Human_blood_group_systems

    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 ...

  6. Mixed-field agglutination - Wikipedia

    en.wikipedia.org/wiki/Mixed-field_agglutination

    Mixed-field agglutination is an important cause of ABO typing and genotype discrepancies. The cause of mixed field agglutinations should be sought prior to setting up blood for transfusion. [ 1 ]

  7. Blood type distribution by country - Wikipedia

    en.wikipedia.org/wiki/Blood_type_distribution_by...

    Blood type (also called a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins , carbohydrates , glycoproteins , or glycolipids , depending on the blood group system.

  8. ABO (gene) - Wikipedia

    en.wikipedia.org/wiki/ABO_(gene)

    Histo-blood group ABO system transferase is an enzyme with glycosyltransferase activity, which is encoded by the ABO gene in humans. [5] [6] It is ubiquitously expressed in many tissues and cell types. [7] ABO determines the ABO blood group of an individual by modifying the oligosaccharides on cell surface glycoproteins. Variations in the ...

  9. Hemagglutination - Wikipedia

    en.wikipedia.org/wiki/Hemagglutination

    To determine between type A or type AB, antibodies that bind the B group are added and if agglutination does not occur, the blood is type A. If agglutination does not occur with either antibodies that bind to type A or type B antigens, then neither antigen is present on the blood cells, which means the blood is type O. [1] [2]
