Sure, Bill, good question. No, there's definitely been a lot of turbulence in the reimbursement landscape in the first half of the year. The largest focus that we have in our own reimbursement effort, we've been, on the hill at least, 50x, 60x in last 6 months in various formats and we've been actively lobbying for there fairer reimbursement rates for both LDTs and also FDA-approved kits. Some of our labs are truly suffering, and we're doing everything we can to support that. Now when the reimbursement rates for LDTs came out in January, clearly that was little bit a shocker for everybody. At the same time, a few weeks later, we were informed that there would be a premium reimbursement rate for FDA-approved kits. And the KRAS reimbursement rate came out that $385, substantially, above where we had the average on the quote stacking. And this has been very favorable for customers who have run the math. Because the difference between the LDT and the FDA reimbursement rate is actually about the price per reportable. And so it is actually economically favorable to use the FDA-approved kit for laboratory compared to the LDT. Nevertheless, the base rate, the LDT rate, is just too low. And there's no question about it. And we're trying to raise that. So we are providing some additional value drivers for our laboratory customers and same will hopefully be true for each follower, where reimbursements rates are going to be sent in the next few weeks. But nevertheless, these differential reimbursements have not yet broadened through the United States. They started only in certain regions or certain coverage areas, and we expect them to go broader. Currently, a lot of laboratories are not getting these premium reimbursement rates, so it has been very difficult to adopt and to accelerate. But this is a something, I think, which is more a matter of time. And to make long things short, we have a very interesting value proposition for laboratories by going through these very, very expensive FDA approval processes. At the same time, laboratories are currently suffering because premium reimbursement rates for FDA-approved products are not available and a lot of them are LDTs, which are not very attractive.
