How Often Can You Safely Donate Plasma?

Overview

Twice Per Week

Plasma donation centers accept two plasma donations from an individual during each seven-day time period. In addition, donors must wait at least one day between plasma donations so the body has time to replenish the plasma that was donated.

After Blood Donation

Because whole-blood donation is more difficult on the body, blood donors must wait eight weeks after donating blood before it is safe to donate plasma again. Plasma donation is different from whole-blood donation because only the plasma is removed, while the rest of the blood is returned to the body.

Bottom Line

People who are eating a healthy diet that includes plenty of protein and fluids can replenish their plasma supply within about 48 hours. People in good health can safely donate plasma twice per week. People who donate whole blood must wait eight weeks before donating plasma.
