Age-dependent regeneration of plasma proteins after donor plasmapheresis.

To analyze age-dependent effects of a plasma donation on the regeneration of plasma proteins, two groups of first-time plasma donors were selected (< 25 and > 50 years). The regeneration kinetics of different plasma proteins until 3 weeks after donation was followed up. It can be concluded that a single plasma donation has an age-dependent effect on regeneration, especially on the prolonged regeneration of cholinesterase and immunoglobulins.
