NCT ID NCT05179200
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at whether donating plasma more often affects protein levels, inflammation, and mental health in male blood donors. 120 men were split into three groups: one donated plasma three times every two weeks, another every two weeks, and a third donated whole blood every three months. Researchers measured blood proteins and psychological distress before, during, and after the 16-week donation period to see if frequent donation is safe.
