Abstract
Methods and systems for maintaining patient fluid balance during an extracorporeal cell treatment are disclosed. The method includes minimizing the amount of saline or other fluid that is returned to the donor. Saline used during priming of the fluid circuit may be used to increase the volume of the collected cells to arrive at a treatment-ready product with a suitable hematocrit.
