Pre transfusion blood tests

A significant proportion of the population lack the Rh D antigen on their red blood cells. This practice of performing type and screen only allows better inventory management of red blood cell supply, as there are more units left available in inventory, and few units being held for a specific patient, unavailable to others.

Autoantibodies Autoantibodies are frequently encountered in pre-transfusion testing, and may be the cause of autoimmune red cell destruction, or may be clinically benign. Blood transfusions fell into obscurity for the next years. The final rule, reflected in updated sections of the CFR, becomes effective on May 23, Intravenous immunoglobulin IVIG is treatment of choice.
