Which wait time is associated with plasma donation?

• A. 24 hours
• B. 12 hours
• C. 72 hours
• D. 48 hours

Answer: (A)

Plasma donation momentarily reduces the circulating plasma volume, so what matters most is how quickly that volume can be restored and the donor can safely resume activity. The body replenishes plasma volume relatively quickly, with a practical minimum recovery period of about 24 hours. Ensuring at least a 24-hour interval helps prevent symptoms like dizziness, lightheadedness, or fatigue that could compromise safety, especially in aviation duties where full physiologic reserve is important. A shorter interval, such as 12 hours, doesn’t give enough time for adequate plasma restoration, while longer intervals like 48 or 72 hours exceed what’s typically required for plasmapheresis recovery. Therefore, the wait time associated with plasma donation is 24 hours.
