What is the correct storage temperature for Fresh Frozen Plasma (FFP)?

Fresh Frozen Plasma (FFP) is stored at temperatures of -18°C or lower to maintain the stability of its clotting factors and other important components. The primary reason for this low-temperature storage is to prevent the degradation of proteins, particularly coagulation factors, which can begin to deteriorate at higher temperatures.

When FFP is stored at temperatures between -18°C and -30°C, it can be kept for up to a year, ensuring that it remains effective for therapeutic use when transfused to patients. Choosing a temperature of -20°C aligns with these recommended storage practices, as it provides a sufficient buffer for long-term preservation.

Other temperatures listed, such as 4°C or 37°C, are unsuitable because they would not properly preserve the functional integrity of the plasma. Storing FFP at these higher temperatures could lead to the rapid deterioration of clotting factors, making the plasma ineffective as a treatment option. Thus, the choice of -20°C is the correct option for the storage of Fresh Frozen Plasma.
