Measure Description |
Time Frame |
|---|---|---|
|
Granulocyte/PMN Cell Collection Efficiency
Time Frame: within 1 hour prior and within 5 minutes after each collection procedure
|
The primary endpoint is the granulocyte/PMN cell collection efficiency (CE) associated with the Granulocyte (PMN) Collection Procedures on the Spectra Optia and COBE Spectra Apheresis Systems.
CE is a measurement of device performance calculated using donor and blood product blood counts collected immediately before and after the PMN collection procedure.
