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.

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]
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
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.
The practice of transfusion medicine involves both laboratory and clinical aspects of transfusion as communication between blood bank and patients, treating specialists and other medical staff is vital in situations such as massive transfusions or transfusion reactions.
