In the liquid state, plasma must be stored at what temperature?

Plasma must be stored at a temperature range of 1 to 6 ˚C to maintain its integrity and functionality. This temperature range is important to prevent the degradation of proteins and other critical components within the plasma, which can occur at higher temperatures. Storing plasma within this range also helps to inhibit the growth of bacteria and other microorganisms that may contaminate the product.

Higher temperatures, such as 22 ˚C, 37 ˚C, or 56 ˚C, would compromise the quality of the plasma by promoting protein denaturation and potentially leading to the loss of coagulation factors and immunoglobulins, ultimately affecting the therapeutic use of the plasma in a clinical setting. Hence, maintaining the appropriate cold storage conditions is crucial for preserving plasma for transfusions or further processing.
