When a unit of packed cells is split into 2 aliquots, what is the expiration time for each aliquot?

When a unit of packed red blood cells is split into two aliquots, the expiration time for each aliquot retains the original expiration date of the unsplit unit. This is due to the fact that the separation process does not alter the overall integrity or storage conditions of the blood components.

Regulatory standards dictate that the expiration date is based on when the blood was collected and how it has been processed, rather than when it is handled for further distribution or use. Therefore, both aliquots must be labeled with the original expiration date, ensuring that they are only used until that date.

After splitting, some other options suggest a short-term expiration based on time frames within the same day or the next morning. However, this does not accurately reflect blood banking practices and the regulations governing the shelf life of blood products. It is important for practitioners to understand the significance of the original expiration date, ensuring patient safety and adherence to the protocols of blood usage.
