So I feel confident that our Signatera accrual in Q3 will have some biomarker state benefit. On the quarterly trajectory of gross margins, I'm very happy to see some COGS headwinds in Signatera when that is driven by an influx of first time patients, which is what we saw in Q2, as Steve described. Finally, I was pleased to see us continue to generate cash even as we double down on the growth investments Steve described for this year. Obviously, that's driven by the revenues and the margins, but also the rapid improvements in the cash conversion dynamics that we talked about earlier in the call. This is really part of the revenue cycle operations that improve ASP, but also allow us to get reimbursed for covered services in a much more timely manner by optimizing the initial claim submission to payers with all the documentation they need to pay the claim on the first path.
