What was measured

Collection efficiency (CE) is defined as the percentage of any given cellular subset, processed by the system, that is collected from the subject. CD34+ is a cell surface marker found on pluripotent hematopoeitic stem cells.

Analysis population: Data to calculate CD34+ cell collection efficiency was available for 39 collections on 24 of 26 per protocol patients.
