Much of the routine work of a blood bank involves testing blood from both donors and recipients to ehat every individual recipient is given blood that is patible and is as safe as possible. If a unit of inpatible blood is transfud between a donor and recipient, a vere acute hemolytic rea with hemolysis (RBC destru), renal failure and shock is likely to occur, ah is a possibility. Antibodies be highly active and attack RBd bind pos of the plement system to cau massive hemolysis of the transfud blood.
Patients should ideally receive their own blood or type-specific blood products to minimize the ce of a transfusioion. Risks be further reduced by atg blood, but this may be skipped when blood is required for an emergency. atg involves mixing a sample of the recipient’s rum with a sample of the donor’s red blood cells and cheg if the mixture agglutinates, or forms clumps. If agglutination is not obvious by direct vision, blood bank teis usually check flutination with a microscope. If agglutination occurs, that particular donor’s blood ot be transfud to that particular recipient. In a blood bank it is vital that all blood spes are correctly identified, so labeling has been standardized using a barcode system known as ISBT 128.
