• Fetal and neonatal recipients of intrauterine transfusions.
• Selected immunocompromised recipients.
• Recipients of cellular components known to be from a blood relative.
• Recipients who have undergone marrow or peripheral blood progenitor cell transplantation.

Which patients should receive irradiated blood components?

• Infants (particularly premature) up to 4, 6, or 12 months depending on institutional policy.
• Intrauterine transfusion* and/or neonatal exchange transfusion recipients.
• Congenital immunodeficiency disorders of cellular immunity (i.e., SCID, DiGeorge)*

Who would need irradiated blood?

Which blood components need to be irradiated? Only cellular blood components (red cells, platelets and granulocytes) need to be irradiated.

Do all patients need irradiated blood?

Is all blood routinely irradiated? Red cell and platelet transfusions are not routinely irradiated and need to be irradiated 'on demand' for patients at risk of TA-GvHD. It is important that you remind your medical team of your need for irradiated blood as they have to order it specially.

When should blood be irradiated?

It has no clinically significant effect on red cell pH, glucose, 2,3 DPG levels or ATP. Packs irradiated within 14 days of collection expire 28 days after collection. Packs irradiated more than 14 days after collection expire either 5 days after irradiation OR at original expiry of pack, whichever comes first.

Why Do We...Irradiate Blood?

Why do you need irradiated blood?

Why is blood irradiated? Irradiated blood is used to prevent a very rare but serious complication of blood transfusions called 'transfusion-associated graft-versus-host disease' (TA-GvHD). This is when donor white blood cells attack your own tissues.

Why is blood irradiation done?

Irradiation (or pathogen inactivation) of blood products is performed to abrogate the risk of transfusion-associated graft-versus-host disease (TA-GVHD), a rare and almost universally fatal complication of blood transfusion with no successful treatment options.

Do immunocompromised patients need irradiated blood?

Irradiation of cellular blood components currently is the only acceptable method for preventing TA-GVHD. Fresh, unfrozen plasma also needs to be irradiated, because it may contain viable lymphocytes. Fresh frozen plasma or cryoprecipitates do not need to be irradiated.

Do CLL patients need irradiated blood?

If you've been treated with fludarabine or bendamustine and you then need a blood transfusion, you'll need to receive blood that has been treated with radiation (irradiated blood). This kills any white cells in the blood going into you and protects you against a very rare type of transfusion reaction.

Why do bone marrow transplant patients need irradiated blood?

Irradiation of blood is done to prevent graft-versus-host disease (GVHD) in susceptible patients getting transfusion.

Is donated blood irradiated?

As described in the Technical Manual (20th Edition) and Circular of Information (October 2017), cellular blood components are irradiated prior to transfusion to prevent the proliferation of viable T lymphocytes which are the immediate cause of Transfusion Associated-Graft Versus Host Disease (TA-GVHD).

What is meant by irradiated blood?

Irradiated blood is blood that has been treated with radiation (by x-rays or other forms of radioactivity) to prevent Transfusion- Associated Graft-versus-Host Disease (TA-GvHD).

What is the difference between irradiated and non-irradiated blood?

Conclusion: Irradiated blood is associated with a greater rise in extracellular potassium compared to non-irradiated but when an irradiated blood washing protocol is implemented prior to transfusion, there is not a significant rise in extracellular potassium.

Why are blood products Leukoreduced and irradiated?

Leukoreduction filters to remove leukocytes are not completely effective. ... Irradiated Blood: Irradiation is needed to destroy all nucleated cells and living leukocytes (white blood cells), particularly lymphocytes that could cause transfusion associated graft versus host disease (TAGVD).

In which situation is gamma irradiation of cellular blood components required?

BLOOD BANKING

Cellular blood components are exposed to γ irradiation to prevent transfusion-associated graft-versus-host disease (TA-GVHD) in susceptible patients²²⁴—a nearly uniformly fatal complication of transfusion.

What is meant by the term irradiated?

1 : exposure to radiation (such as X-rays or alpha particles) 2 : the application of radiation (such as X-rays or gamma rays) for therapeutic purposes or for sterilization (as of food) also : partial or complete sterilization by irradiation.

Do AML patients need irradiated blood products?

Blood products must be irradiated to prevent transfusion-associated graft versus host disease (GVHD).

Can CLL patients donate blood?

If you have ever had lymphoma or leukemia, or any other blood cancer as an adult, then you cannot donate your blood to the Red Cross.

Can CML patients donate blood?

Those who have had blood-related cancers (such as leukemia and lymphoma as an adult) may never donate blood.

Do blood transfusions make you immunocompromised?

Another effect of receiving a blood transfusion, immunosuppression, causes a decreased immune response that compromises patients' ability to fight off infection or tumor cells. These effects - sensitization and immunosuppression - are thought to be due largely to white blood cells present in the transfusion product.

Is CMV negative irradiated?

Therefore only red cells, platelets and granulocytes require irradiating. CMV negative: The status of CMV negative applies to red cells and platelets only. Irradiating red cells shortens the expiry to 14 days.

Do blood transfusions weaken immune system?

Transfused blood also has a suppressive effect on the immune system, which increases the risk of infections, including pneumonia and sepsis, he says. Frank also cites a study showing a 42 percent increased risk of cancer recurrence in patients having cancer surgery who received transfusions.

How does irradiation prevent GVHD?

Gamma irradiation of blood products has been the mainstay of TA-GVHD prevention. Dose of 2500 cGy is required to completely inactivate T cells. Irradiation damage red cells membrane and the red celis units can not be storage for long time after irradiation. High potassium levels is the mainly change in red cells units.

What does an irradiator do?

Irradiators are machines that expose products to gamma radiation to kill germs and insects or for other purposes. Food, food containers, spices, fruits, plants and medical supplies are the products most commonly irradiated. The process does not leave radioactive residue or cause the products to become radioactive.
