Doubling the 30-minute rule

The Issue

Doubling the 30-minute rule to reduce waste without compromising red blood cell quality and safety

Since the 1970s, blood operators have limited the length of time red blood cells (RBCs) can be exposed to uncontrolled temperatures to 30 minutes. Called the “30-minute rule”, this international standard was put in place to keep cells usable and limit bacterial growth. However, it is not always possible to transfuse a patient within 30 minutes. As a result, thousands of RBCs are discarded.
