  2. 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.

  3. ABO blood group system - Wikipedia

    In fact, having type O blood predisposes to bleeding, [51] as 30% of the total genetic variation observed in plasma vWF is explained by the effect of the ABO blood group, [52] and individuals with group O blood normally have significantly lower plasma levels of vWF (and Factor VIII) than do non-O individuals.

  4. Blood type - Wikipedia

    en.wikipedia.org/wiki/Blood_type

    A complete blood type would describe each of the 45 blood groups, and an individual's blood type is one of many possible combinations of blood-group antigens. [3] Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease.

  5. Kell antigen system - Wikipedia

    en.wikipedia.org/wiki/Kell_antigen_system

    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.

  6. Human leukocyte antigen - Wikipedia

    Haplotypes can be obtained by typing family members in areas of the world where SSP-PCR is unable to recognize alleles and typing requires the sequencing of new alleles. Areas of the world where SSP-PCR or serotyping may be inadequate include Central Africa, Eastern Africa, parts of southern Africa, Arabia, S. Iran, Pakistan, and India.

  7. Cross-matching - Wikipedia

    en.wikipedia.org/wiki/Cross-matching

    Cross-matching or crossmatching is a test performed before a blood transfusion as part of blood compatibility testing. Normally, this involves adding the recipient's blood plasma to a sample of the donor's red blood cells. If the blood is incompatible, the antibodies in the recipient's plasma will bind to antigens on the donor

  8. Tissue typing - Wikipedia

    en.wikipedia.org/wiki/Tissue_typing

    Tissue typing is a procedure in which the tissues of a prospective donor and recipient are tested for compatibility prior to transplantation. Mismatched donor and recipient tissues can lead to rejection of the tissues.

  9. Rh blood group system - Wikipedia

    en.wikipedia.org/wiki/Rh_blood_group_system

    The name rhesus factor (Rh) goes back to the use of erythrocytes extracted from the blood of rhesus monkeys for obtaining the first blood serum. The Rh blood group system is a human blood group system. It contains proteins on the surface of red blood cells. After the ABO blood group system, it is the most likely to be involved in transfusion ...
