GlossaryA List of Commonly Used Terms in Blood Banking
A storage set used for red blood cells that divides the original RBC unit into four total bags for use primarily in pediatric or neonatal transfusions. The blood collection center prepares a unit of RBCs and divides it into four bags with equal volumes under sterile, closed-system conditions. A hospital transfusion service may then remove only a single small bag for transfusion to a patient with a low blood volume, leaving the rest of the units intact and undisturbed. In this way, a single unit may be used for multiple transfusions to a single patient over time, limiting exposure to multiple donors.
