What is the recommended storage temperature for red blood cells?

Keeping red blood cells cold slows their metabolic rate, preserves membrane integrity, and reduces byproducts that can cause damage over time. This refrigeration is essential to maintain viability for transfusion, and the standard practice is to store most RBC units at 1 to 6 degrees Celsius. Within this range, cells remain functional for weeks when used with appropriate additive solutions. Storing at room temperature would accelerate metabolism and waste buildup, shortening shelf life, while freezing at -18°C is not appropriate for routine storage because it damages the cells unless specialized cryopreservation methods are used.
