If plasma is donated no more than every 4 weeks (infrequent donor), the donor assessment procedures are the same as for whole blood. The FDA limitations for plasma removal are no more than 800 mL of plasma at one donation depending on the donor’s weight. These volumes may be slightly different when semiautomated instruments are used. Donors may give again in 48 hours as for platelets, but not more than twice within a 7‐day period. For donors undergoing plasmapheresis more often than once every 4 weeks (frequent donor), the serum protein must be monitored and found to be within normal limits.
