Question

Expiration time for reinfusion of processed, washed cells is?

A) 6 hours if refrigerated
B) 8 hours at room temperature
C) 6 hours at room temperature
D) 24 hours at room temperature

Answer 1

The correct expiration time for reinfusion of processed, washed cells is 6 hours at room temperature to prevent the risk of bacterial contamination and ensure the efficacy of the cells.

Step-by-step explanation:

The expiration time for reinfusion of processed, washed cells is C) 6 hours at room temperature. It is crucial to adhere to this timeframe to ensure the safety and efficacy of the reinfused cells. Once processed, the cells should not be kept at room temperature longer than six hours due to the risk of bacterial contamination and degradation of the cells, which might affect their functionality.

Reticulocytes, which are immature red blood cells (erythrocytes), are released into the bloodstream and typically mature within one to two days. Mature erythrocytes then circulate in the bloodstream for an average of 120 days. This lifespan is important to consider when handling and reinfusing blood products, as the goal is to maintain the viability and function of the cells throughout their intended lifespan.
