Frequently Asked Questions about Leukodepleted Blood Transfusion

Updated: Jan 19

Leukodepletion filters play a pivotal role in numerous medical procedures, necessitating a clear understanding of their purpose and functionality. In this blog post, we aim to answer the frequently asked questions surrounding leukodepletion filters.


1. What is Leukodepletion?

Leukodepletion is the process of reducing the number of white blood cells (leukocytes) in blood products. This is achieved through specialized filters designed to selectively eliminate these cells while preserving the integrity of other blood components.

2. Why is Leukodepletion important?

Reason for removing leukocytes from blood before transfusion

Leukocyte-depleted Blood Transfusion is Recommended because Leukodepletion holds considerable importance in medical procedures involving blood transfusions and blood components. By eliminating white blood cells, the risk of adverse reactions, such as febrile non-hemolytic transfusion reactions and transfusion-related acute lung injury (TRALI), is significantly diminished. Additionally, leukodepletion enhances the quality and lifespan of stored blood products.


3. What is the Mechanism of Leukocyte Removal by Filtration?

mechanism of leukodepletion filter

Leukodepletion filters employ diverse mechanisms to separate white blood cells from other blood components. One common method involves using porous materials that permit smaller components like red blood cells and platelets to pass through while entrapping larger white blood cells. This ensures that the filtered blood product is relatively devoid of leukocytes.


4. In Which Medical Procedures are Leukodepletion Filters Utilized?

Leukodepletion filters find application in various medical procedures, including blood transfusions, organ transplantation, and the collection of blood components for further processing. Their use is particularly crucial in patients with a history of transfusion reactions or those who are immunocompromised.

5. Are Leukodepletion Filters common in Blood Banks?

While the utilization of leukodepletion filters has become increasingly prevalent, it may not be universal in all blood banks. However, many health organizations and regulatory bodies advocate or mandate the use of leukodepletion filters to enhance the safety and quality of blood products.


6. How do leukodepleted transfusion benefit patients?

benefits of leukodepletion filters

Patients who receive leukodepleted blood experience a significant reduction in adverse reactions post-transfusion. For example, febrile non-haemolytic transfusion reactions, which often cause fever and chills, are notably minimised. This translates to a more comfortable and smoother recovery for patients, speeding up their healing process and promoting a sense of security during treatment.
