What happens to fresh whole blood that hasn't been used within a certain time frame at room temperature?

Fresh whole blood that has not been used within the established time frame at room temperature must be destroyed to prevent potential health risks. When blood is stored at room temperature, it can rapidly become a medium for bacterial growth, which can lead to infections if transfused. The safety protocols for blood transfusions are very strict due to these risks, which prioritize patient safety above all else.

The requirement for timely use ensures that the blood maintains its effectiveness and safety for transfusion. Keeping blood at room temperature for extended periods can compromise its quality and increase the likelihood of transfusion reactions. Thus, the only safe option when it has been stored improperly is to render it unusable and destroy it.

Other options, such as reprocessing or refrigerating, are not acceptable practices for fresh whole blood that has exceeded the time limit. Blood cannot simply be reprocessed to restore its safety, nor is it appropriate to try to refrigerate it once it has been stored at room temperature beyond the designated time limits, as this would not mitigate the risks associated with bacterial contamination.
