Leukocytapheresis in nonmobilized donors for cellular therapy protocols: Evaluation of factors affecting collection efficiency of cells.

Donor's age, preprocedure CBC data as well as central line used as vascular access were factors associated with CE1 of cells. Knowing these characteristics is helpful in the apheresis unit when designing cellular therapy protocols in order to maximize the CE1 of the desired cell and to personalize collection variables for each donor.
