Esteria Mbugi: When a Simple Filter Can Protect A Patient’s Life
Esteria Mbugi, Medical Laboratory Scientist at Mbeya Zonal refferal hospital, shared a post on LinkedIn:
“When a Simple Filter Can Protect A Patient’s Life.
A young leukemia patient receiving repeated blood transfusions started developing fever and chills after transfusion reactions.
For such patients, transfusion is not just about replacing blood it is about making every unit as safe as possible.
Today in the blood bank, I had the opportunity to prepare leukoreduced blood components as part of my work as a Medical Laboratory Scientist.
What is leukoreduction?
Removing white blood cells from blood components using a special filter. A standard unit goes from billions of WBCs down to less than 5 x 10⁶.
During the process, the blood unit is passed through a specialized leukocyte reduction filter to remove most white blood cells (leukocytes) before transfusion.
This step is extremely important because residual leukocytes can contribute to febrile non-hemolytic transfusion reactions, HLA alloimmunization, platelet refractoriness, and increase the risk of CMV transmission in vulnerable patients.
Who needs leukoreduced blood?
- Cancer/leukemia patients (risk of alloimmunization)
- Thalassemia and sickle cell (frequent transfusions)
- Organ transplant candidates (to prevent rejection)
- Premature infants and CMV-negative pregnant women
Without leukoreduction, donor white blood cells can cause fever, organ damage, or make future platelet transfusions useless.
What looked like a routine preparation today carried a much deeper meaning improving transfusion safety for patients who already have enough battles to fight.
Moments like this continue to strengthen my passion for Transfusion Medicine and Blood Banking.”
