What is the expiration labeling for each aliquot of Red Blood Cells split from a unit expiring in 35 days?

The expiration labeling for an aliquot of red blood cells that is split from a unit expiring in 35 days is indeed 35 days. This is because when red blood cells are split into aliquots, the expiration date for each aliquot remains the same as that of the original unit from which it was derived, provided that the aliquoting process is done aseptically and the storage conditions for the aliquots are appropriate.

Aliquots are typically prepared to allow for smaller doses of blood products to be used in patients, thereby minimizing waste and ensuring compatibility with the patient's needs. The original expiration date indicates the period during which the red blood cells are safe to use, taking into account their storage and handling. Since the original unit expires in 35 days, each aliquot retains this same expiration period.

Maintaining the expiration date of the original unit for the aliquots is crucial for ensuring patient safety. If the aliquots were labeled with a shorter expiration period, it could lead to confusion and the potential for using a unit beyond its safe usage timeframe. It's important for blood bank personnel to accurately manage these details to provide the best care for patients receiving blood products.
