Why Is This Process Necessary? The primary purpose of irradiating blood is to prevent Transfusion-Associated Graft-versus-Host Disease (TA-GVHD). This energy disrupts the DNA of remaining donor lymphocytes, rendering them unable to divide and cause an immune reaction in the recipient.

The process involves exposing the blood product to gamma rays or X-rays in a controlled environment. The process does not significantly alter the red blood cells' ability to carry oxygen, making them a vital alternative for patients with specific immunological vulnerabilities.
While the immune system of a healthy person would reject these foreign cells, patients with weakened immune defenses cannot. This condition occurs when viable donor T-lymphocytes attack the tissues of an immunocompromised host, a scenario with a high mortality rate.

Storage and Shelf Life Considerations Irradiation can introduce subtle changes to the red blood cells during storage, primarily related to the storage lesion. Recipients of intensive chemotherapy or high-dose corticosteroid therapy.
