21 days

28 days

35-42 days

Red blood cell (RBC) units, when stored in refrigeration, can typically last for 35 to 42 days. This storage duration is crucial for ensuring that the RBCs maintain their viability and functionality for transfusions. The extended storage period is made possible due to the use of specific anticoagulants and preservatives that protect the cells and their hemoglobin while they are stored under controlled temperature conditions, which are generally between 1°C and 6°C.

Understanding the correct storage duration is essential for medical personnel involved in blood management, as it impacts the availability of blood products for patients in need of transfusions, particularly in emergency or surgical situations. This knowledge ensures that healthcare providers can effectively plan and manage blood supplies while minimizing wastage and optimizing patient care.
