Thanks, Helmy. Turning to slide 19. I'll discuss our revenue results for the three months ended June 30, 2024 and refer to year-over-year growth rates, unless otherwise noted. Total revenue grew 29% to $177.2 million, driven by precision oncology revenue, which increased 33% to $166.5 million. Precision oncology revenue from clinical tests increased 30% to $130.2 million. Clinical test volume grew to a record 49,400 tests in Q2 2024. Clinical volume growth of 14% was in line with our expectations, which factored in the uptick in volume we experienced in the second quarter of 2023, following the Guardant360 CDx approval for ESR1. For the second quarter of 2024, we again saw year-over-year volume growth for Guardant360 in the US, increased Guardant360 volume contribution from Japan and the UK, and strong volume growth for both Reveal and TissueNext. For the full year 2024, we continue to expect clinical volume growth to be approximately 20%. Our biopharma business performed incredibly well in the second quarter, with precision oncology revenue from biopharma tests totaling $36.2 million, increasing 45%. This exceptional growth was fueled by a record number of tests in the second quarter, 10,475, which was up 56%. We continue to expect our biopharma business to perform well, and have increased our biopharma revenue growth expectation for the full year 2024 to now be in the high teens, compared to our previous expectation of low teens revenue growth. Finally, development services and other revenue totaled $10.7 million. Turning to Guardant360 ASPs on slide 20. We are very pleased to report that we again saw strong cash collections for Guardant360 in the second quarter of 2024, driven by continued improvements in both Medicare Advantage and commercial reimbursement. These improvements led to a step up in the Guardant360 ASP range from $2,950 to $3,000, an increase from the range of $2,900 to $2,950 in Q1 2024, and from approximately $2,650 in Q2 2023. These improved trends also give us confidence that the Guardant360 ASP can remain in this new range for the remainder of 2024. In Q2 2024, we also had a revenue upside of approximately $8 million related to cash collected for Guardant360 tests performed in prior periods. This was similar to the upside we recorded in Q1 2024, and reflects the continued tailwind of improved collections. Although it's early days, we believe we will achieve the long-term ASP targets we presented at our Investor Day earlier than originally anticipated, which could potentially bring forward our timeline to reach company-wide cash flow breakeven. Moving on to non-GAAP financial measures on slide 21. Our non-GAAP gross margin excluding screening, which reflects our therapy selection and MRD businesses, was 62% in the second quarter of 2024 and was in line with our full year guidance of 61% to 63%. Compared to Q2 2023, non-GAAP gross margin excluding screening decreased to a 62% from 64% due to test and revenue mix. Specifically, in Q2 2024, we saw an increase in the mix of negative gross margin Reveal tests in the precision oncology revenue line, as well as a decrease in the mix of 100% gross margin milestone royalty revenue in the development services and other revenue line. Non-GAAP operating expenses were $178.8 million, a reduction of $1.7 million compared to the prior-year quarter. This decrease was primarily driven by lower clinical study costs following the completion of ECLIPSE enrollment in Q3 last year and a decrease in G&A expense. These decreases were offset by an increase in sales and marketing expense in preparation for the Shield IVD commercial launch and in support of the continued growth of our therapy selection and MRD revenue. We continue to tightly control our operating expenses by leveraging the infrastructure we've built to support all of our businesses and by gating our commercial spend on specific milestones. For the second half of 2024, we expect R&D and G&A expenses to be similar to the first half of the year and expect sales and marketing expense to increase, now that we're firmly in those launch phase for Shield and we'll be ramping up the number of field sales reps to 100 by the end of the year. As a result of our increased revenue and reduction in operating expenses, our registered EBITDA loss was $61.9 million in Q2 2024, a decrease of $23.3 million from $85.2 million in Q2 2023. Free cash flow for the second quarter of 2024 was negative $99.1 million compared to negative $100.5 million in Q2 2023. The year-over-year change reflects a decrease in operating cash burn and equipment purchases, offset by an increase in the annual bonus payout, which is made in April each year. We ended the second quarter of 2024 with over $1 billion in cash, which we continue to believe is sufficient to enable us to achieve our goal of reaching cash flow breakeven by 2028 or potentially earlier. Now turning to our outlook and assumptions for the full year 2024 on slide 22. We're pleased to be able to increase our revenue guidance and now expect full year 2024 revenue to be in the range of $690 million to $700 million, representing growth of approximately 22% to 24% compared to 2023. This increase reflects the cash collection upside we had in the second quarter, the increase in the Guardant360 ASP that we expect for the remainder of the year and the increased full year expectation for our biopharma business. As a reminder, this revenue guidance does not include any contribution from screening. Although we've now successfully launched Shield IVD, obtained Medicare coverage and started to receive samples into the lab, it's still very early days and the Medicare gap fill rate is yet to be established. As such, we'll begin to provide screening revenue guidance at a more appropriate time in the future. We continue to expect non-GAAP gross margin excluding screening to be in the range of 61% to 63% and non-GAAP operating expenses to be in a range of $720 million to $730 million, representing a flat to 1% decline year-over-year. Finally, we continue to expect free cash flow for 2024 will be in the range of negative $275 million to $285 million, an improvement of $60 million to $70 million compared to 2023 and that our therapy selection business will deliver positive free cash flow for the full year 2024. We also continue to expect the maximum screening cash burn this year to be $175 million. Our increased revenue expectation enables us to maintain this free cash flow range while providing us with further flexibility to manage potential working capital fluctuations in the back half of the year, as well as the potential to bring forward capital purchases to accelerate our capacity expansion and automation efforts. Finally, turning to slide 23 to review our catalysts. We've already made significant progress on milestones across each of our business areas in the first half of the year. As we look ahead to the rest of 2024, we're very excited by the potential opportunities across therapy selection, MRD and screening. With that, we'll now open the call to questions.
