According to AABB standards, how must Platelets be stored?

Platelets must be stored at room temperature and gently agitated to maintain their viability and function. The agitation helps prevent the platelets from clumping together, which can adversely affect their ability to circulate and perform their role in hemostasis. This storage condition is critical because platelets are sensitive to temperature variations and require a specific environment to remain active and usable for transfusion purposes.

The standard to agitate platelets at room temperature ensures that they retain their functionality and can be effectively utilized in clinical settings when patients require platelet transfusions. This is especially important for patients with thrombocytopenia or other conditions affecting platelet production or function.

Other choices refer to various aspects of blood component processing or storage that are not aligned with the established guidelines for platelet storage. For instance, platelets should not be stored in a pH of 5.0 or lower, nor should they be prepared solely from Whole Blood units that were stored under specific conditions unrelated to platelet maintenance.
