Great post and thanks for the vine. Why not develop an assay to measure cytokine levels and other important toxins that the beads are known to remove or reduce. We would call this an accompanying diagnostic and the addition of the measuring stick would turn the filter into a theragnostic therapy. Much easier to measure efficacy and know when to initiate, when to continue and when to terminate treatment. This form of personalized medicine is really becoming more the norm in critical care medicine every day. This from my nephrologist friend.
