The Persona Nomogram Story
The plasma collection system of the future.
The simple nomogram in place since 1992 was based solely on an
individual’s weight. It allowed three plasma collection volumes according
to whether the donor fell into the small, medium or large weight category.
The Persona Nomogram is a novel, personalized percent plasma
nomogram based on body mass index and hematocrit, enabling a more
tailored collection target using individual donor characteristics.
In a multicenter, prospective, double-blinded, randomized controlled clinical trial involving 3,443 donors who underwent 23,137 plasma donations - one of the largest plasmapheresis trials ever conducted:
- Using NexSys PCS with Persona resulted in an average increase in
volume of plasma collected per donation across the study population.
- The number of repeat donations was not impacted and increasing plasma collection volume up to a maximum of 1,000 mL was well tolerated in eligible donors.
