What is the proper storage temperature for red blood cells?

The proper storage temperature for red blood cells is between 1°C to 6°C. This temperature range is crucial for maintaining the viability and functionality of red blood cells. When stored at this range, the metabolic activity of the cells is decreased, helping to preserve their integrity for transfusion. Storing red blood cells at temperatures colder than 1°C may cause freezing, which can damage the cells and compromise their ability to function after transfusion. Conversely, temperatures above 6°C can lead to bacterial growth and reduce the shelf life of the blood product. Therefore, maintaining red blood cells at 1°C to 6°C ensures they remain safe and effective for use in transfusions.
