Yes. Glad you brought it up. So we are very encouraged by the work that we are doing in kidney disease. I think we've got some exciting science at the organization. We've got really two development efforts, one in lupus nephritis, which takes us deeper into the autoimmune space and there is a high clinical need within a subset of SLE patients. But basically, approximately half of all lupus patients end up developing some form of kidney involvement or lupus nephritis. Diagnosis now is by kidney biopsy, and there are treatments out there, biologics out there, but you don't know after an extended period of time if the patient is responding. And during that period of time, the kidneys can continue to experience irreversible damage. So we have programs in place that potentially could serve as a diagnostic capability in that context, along with a measurement of disease activity or a measurement of therapeutic response. So very excited there. We've really worked hard to hedge our bets as we've done in many instances. And in the development efforts for lupus nephritis, we thought, hey, there may be an opportunity for us to look at broader biomarkers of kidney damage. And that's exactly what we've done. Excited, because this is a high clinical need and really, there's a significant patient need here. And so from our -- and the tools that exist in terms of standard of care are not very satisfactory. So the markers we're developing have broad applicability in multiple diseases. We have now validated in early diabetic kidney disease along with lupus nephritis. And again, that was the data that was shared in that biomarker Summit in Boston by Dr. Mike Nerenberg, our Chief Medical Officer, but this is a huge patient need. So chronic kidney disease impacts on the order of 14% to 15% of the U.S. population. Diabetes prevalence in the U.S. is somewhere around 11% to 12%. Either of those patient populations are substantial, obviously, when you take a look at the U.S. population. So excited about the potential of these markets, how we approach them and commercialize them is too far out in the future for us to comment at this point in time. We're really just focusing on the science. The science is encouraging, we are getting it out in the public domain. There'll be a manuscript out later this year, which details the findings as well, but very exciting for us. And I think maybe the other thing I will just add Mark, is you see a lot of progress on the SGLT2 and GLP-1 fronts where they're actively working on expanding labels or they already have, in some instances, labels for chronic kidney disease in the early stage and being able to identify these patients better than the current standard of care is an exciting opportunity for us.
