What are the guidelines for blood product storage temperatures?

The correct choice outlines the universally accepted guidelines for storing various blood products at specific temperatures, which is critical for maintaining their viability and functionality.

Red blood cells are stored at temperatures between 1°C and 6°C. This temperature range helps preserve the integrity and lifespan of the red blood cells by slowing down metabolic processes and reducing the risk of hemolysis. According to established practices, the preferred range is often cited as 2°C to 8°C, but 1°C to 6°C is also acceptable under many protocols.

Platelets require a storage temperature of 20°C to 24°C. This higher temperature range is essential because it maintains platelet activation and function, which are crucial for effective hemostasis. At lower temperatures, platelets can become less viable and may not function correctly when transfused into patients.

For plasma, the recommended storage temperature is -18°C or colder. Plasma stored at these temperatures can be preserved for extended periods, maintaining the stability of clotting factors and other components crucial for transfusions. This allows plasma to be used effectively in various clinical scenarios, particularly in patients who require rapid hemostatic support.

This combination of storage temperatures is vital for ensuring that blood products remain effective and safe for transfusion, thereby
