What is the waiting period after plasma donation?

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

Answer: (B)

After plasma donation, safety hinges on how quickly the body can restore circulating plasma volume and proteins. Plasma volume is replenished relatively quickly, typically within about a day, so a 24-hour waiting period is a practical minimum that protects donor stability while still allowing relatively frequent donations. Shorter gaps, like 12 hours, could risk insufficient recovery; longer gaps, such as 48 or 72 hours, would unnecessarily slow donation frequency without adding substantial safety benefits for healthy donors.
