Within what time frame must platelet concentrates be prepared from collected whole blood?

Platelet concentrates must be prepared from collected whole blood within a specific timeframe to ensure the viability and functionality of the platelets. The correct timeframe is 6 hours. This limit is established based on the need to minimize the risk of bacterial contamination and to maintain the quality of the platelets for transfusion. Preparing the platelets within this timeframe helps retain their hemostatic function and reduces the potential for adverse reactions in transfusion recipients.

In practice, this means that after the whole blood is collected, the process for separating and preparing the platelets must begin promptly to adhere to regulatory and quality standards in blood banking. Ensuring this preparation occurs within the specified 6-hour window is critical for the safety and efficacy of platelet transfusions.
