Thanks, it all makes sense. As the KPMG report makes clear, detection of LPS is always a problem. So, if BPI is blocking the LPS/LBP interaction with CD14, one would think that it's doing so by binding to LPS itself. But maybe this LPS can still be detected in their assay. In other words, can they distinguish free LPS from LPS bound to something (presumably BPI) that may neutralize it?

Now, my understanding is that in this study *detected* LPS levels were similar in treated and untreated animals. Your last comment suggests that they were "similar low" as opposed to "similar high" so that in both groups LPS is being cleared. Of course, LBP, your proposed "clearing agent," is present (who knows at what levels? did they check? this would be a nice test of the LBP tests, wouldn't you say?) in both groups, treated and untreated. Am I reading this right?
