Table 1. Sepax and COBE Red Blood Cell Volume Reductions.

Red blood cell (RBC) volumes before and after processing for both the Sepax and the COBE. Values from each run are shown along with the average of each individual column. Three runs were carried out for the 10x comparison, and two runs for the 12x and 15x comparison runs.
