What percentage of red cells must be retained in leukocyte-reduced red cells?

What percentage of red cells must be retained in leukocyte-reduced red cells?

• A. 75%
• B. 80%
• C. 85%
• D. 100%

Answer: (C)

Leukocyte-reduced red blood cells are prepared to minimize the presence of white blood cells in transfusions, which helps reduce the risk of febrile non-hemolytic transfusion reactions and other immune complications. The standard practice in the blood banking field dictates that a significant percentage of red blood cells must be retained to ensure sufficient oxygen-carrying capacity for the patient receiving the transfusion. The requirement for retaining 85% of the red cells in leukocyte-reduced preparations is based on maintaining the functional integrity and efficacy of the blood product while effectively removing white blood cells. This percentage strikes a balance between ensuring that the transfusion remains clinically effective in supporting the patient's needs and minimizing the potential adverse reactions associated with residual leukocytes.
