Thanks, AmirAli. Turning to Slide 20. I'll now discuss some select financial highlights for the quarter and year ended December 31, 2024. I’ll refer to year-over-year growth rates unless otherwise noted. Fourth quarter, total revenue grew 30% to $22 million, primarily driven by precision oncology revenues, which also increased 30% to $185 million. Precision Oncology revenue from clinical tests increased 35% to $146 million. Clinical tests volumes grew 24% to a record 57,300 tests in Q4 2024 and was primarily driven by Guardant360 which grew sequentially in the mid-single-digits. We continue to see very strong uptake of our upgraded Guardant360 Liquid, which we launched in our Smart Liquidity Biopsy platform at the start of Q3. We also saw continued strong growth of Reveal and tissue during the fourth quarter of 2024. Guardant360 ASP in the fourth quarter of 2024 was approximately $3,000. As we have seen throughout the year, we also had very strong commercial payer collections in the fourth quarter, which led to an after period revenue upside of approximately $8 million above our expectations. Once again, our Biopharma business performed incredibly well in the fourth quarter with Precision Oncology revenue from Biopharma Tech totaling $39 million, increasing 15%. This strong growth was fueled by another record quarter of tests in the fourth quarter, 11,050, which was up 16%. Finally, development services and other revenue totaled $17.2 million in Q4 2024 and includes $4.1 million screening revenue generated from the 6,400 Shield tests that we reported in the quarter. For the full year 2024, total revenue grew 31% to $739 million, with growth again being primarily driven by Precision Oncology revenue which increased 34% to $688 million. Precision Oncology revenue from clinical tests increased 34% to $543 million. Clinical test volume in 2024 was 206,700, which represents growth of 20%. As Helmy mentioned, clinical volume growth was largely driven by an increasing Guardant360 test volumes which grew double-digits in 2024. We saw continued strong growth of Reveal throughout the year, which despite this managing volumes ahead of Medicare surveillance reimbursements was our fastest growing clinical test in 2024. Finally, tissue also grew stronger throughout 2024. Clinical tests revenue growth was also driven by significant improvements through our Guardant360 ASP which increased from approximately $2,750 in the fourth quarter of 2023, to approximately $3,000 in the second half of 2024. In addition to this tailwind, the significant improvement in reimbursement trends throughout the year, that is to collect more cash for our tests than we have previously accrued for, which resulted in after period revenue upsides throughout the year. For the full year 2024, revenue recorded for tests performed in prior years was approximately $35 million. Of this $35 million, approximately $13 million was consistent with our expectations based on the historical experience in payment trends. However, the remaining $22 million was the result of better than expected cash collections and we view this as a non-recurring after period revenue upside for 2024 Turning to Biopharma. As mentioned earlier, our biopharma business performed incredibly well during 2024, with Precision Oncology revenue from Biopharma tests circling $145 million, increasing 31% and Biopharma test volume growing 35% to 40,500 tests during the full year 2024. Finally, development services is and other revenue totaled $51.1 million for the full year 2024 and includes $5.1 million of screening revenues generated from Shield tests that were reported between the IVD launch at the start of August and the end of the year. Moving on to Slide 21. Our non-GAAP gross margin continues to be very strong and was 63% in the fourth quarter of 2024, compared to 61% in the fourth quarter of 2023. We also saw an improvement on an annual basis with 2024 non-GAAP gross margin of 62% compared to 61% in 2023. Excluding screening, non-GAAP gross margin 64% for both the fourth quarter and full year 2024, an improvement from 63% in the prior year period and above the full year guidance range of 61% to 63% that we provided on our Q3 year earnings call. Non-GAAP operating expenses were $215 million in the fourth quarter of 2024, an increase of 17% and $757 million for the full year 2024, an increase of 4%. Our full year non-GAAP operating expense was above our guidance range of $720 million to $730 million due to a couple of one-time items in the fourth quarter of 2024. Firstly, we incurred significant litigation expense related to the November false advertising trial of which the jury unanimously found in favor of Guardant Health on all its claims and awarded us $293 million. Secondly, in Q4, we increased the full year accrue for the 2024 company bonus plan in line with the Board approved pay out level, which reflects a successful year with respect to bonus performance components such as top and bottom line financial measures, the FDA approval of Shield and the launch of new products. With the results of our increased revenue, gross profit at an operating leverage both our adjusted EBITDA and free cash flow improved year-over-year and full year 2024. Adjusted EBITDA loss was 258 million for the full year 2024 an improvement of $86 million, compared to a loss of $344 million in 2023. We continue to be focused on cash and materially reduced our burn in 2024. Free cash flow burn of $275 million for the full year 2024 was in line with the guidance we provided on our Q3 earnings call and represents an improvement of $70 million compared to $345 million in 2023. I'm also pleased to report that our core Therapy Selection business was free cash flow positive in 2024 and that we successfully managed our cash burn for screening to be in line with our guidance target of approximately $175 million. Turning to the balance sheet on Slide 22. We ended the year with approximately $944 million in cash, cash equivalents, restricted cash and marketable debt securities. Earlier this month, we successfully completed a private convertible debt exchange where we extended the maturity on $600 million of convertible debt with favorable terms, which we believe helps to mitigate potential balance sheet risk, while at the same time provides greater optionality to optimize our capital structure in the future. The $600 million of new convertible debt is now due in 2031 and comes with a 1.25% annual coupon and a 35% conversion premium, which represents a conversion price of $62.22. As a result of the transaction, our total debt was reduced from $1.15 billion to $1.09 billion, of which $491 million is our zero coupon convertible debt, which is due in November 2027. We also structured a concurrent stock repurchase of $45 million to help mitigate dilution. Following these transactions, our pro forma cash position was approximately $887 million. We continue to expect that we will reach cash flow break even in 2028 with cumulative free cash outflows of $450 to $550 million over the next three years. Turning to Slide 23, before discussing our outlook and assumptions for 2025, we want to take a moment to preview how we intend to present our revenue going forward. Rather than splitting revenue into Precision Oncology and development services and other, we are changing the presentation to better reflect our different business lines and to provide clarity on the performance of Shield. AS such, for 2025 was about to break out revenue to four components which as shown in this slide with 2023 and 2024 full year numbers. In summary, the new revenue components are Oncology which represents Clinical Therapy Selection, and MRD testing revenues, which we've previously reported as clinical testing revenues within the Precision Oncology line. Biopharma and data, which represents the total revenue we generate from our biopharma customers namely biopharma sample testing revenue that we previously reported in Precision Oncology, as well as biopharma companion diagnostic and data services revenue that we previously reported as development services. Licensing and other, which was previously reported as other revenue and finally screening, which will represent Shield testing revenues. Moving to Slide 24 for our Outlook and assumptions for full year 2025. We expect full year 2025 revenues to be in the range of $850 million to $860 million, representing growth of approximately 15% to 16%, compared to 2024. Excluding the $22 million non-recurring out of period upside in 2024, this range implies total revenue growth of 19% to 20% in 2025. Now, breaking down the key assumptions in our revenue guidance. We expect oncology revenue to grow approximately 15% year-over-year in 2025, again, excluding the non-recurring out of period upside in 2024. This represents oncology revenue growth of approximately 20%. Given the positive traction we're seeing from our launch of Guardant360 LDT or Smart Liquid Biopsy, our recent Medicare CRC surveillance coverage for Reveal and the upgrades we're making to our tissue tests, we expect volumes across all oncology clinical products to accelerate in 2025 and total oncology clinical volume growth to be approximately 25%. We expect our biopharma business to continue to perform well in 2025 and are forecasting low-double-digit growth for biopharma and data revenues. Finally, although it's still very early into the launch, we want to provide some initial guidance for screening revenues, which we expect to be in the range of $25 million to $30 million driven by 45,000 to 50,000 Shield tests. We expect this full year volume to be significantly back-end loaded due to the time it will take to ramp up the productivity of newly hired reps throughout the year. Also, our guidance does not include any ASP impact from receiving ADLT designation, we continue to expect this to occur in 2025 and we'll update our guidance accordingly at the appropriate time. We've made great progress in reducing our COGS over the last few months. With both Reveal and Shield, reaching gross margin breakeven, for 2025, we're confident that we can deliver full year non-GAAP gross margins in the range of 62% to 63% despite the impact of changes in product mix that we expect during the year. We expect total non-GAAP operating expenses to be in the range of $815 million to $825 million, representing an 8% to 9% increase compared to 2024. We will continue to gain significant operating leverage during 2025 and expect R&D and G&A expenses to be relatively flat compared to 2024 with the increase in operating expense coming mainly from investments in screening sales and marketing as we continue to ramp up our commercial efforts for Shield. Lastly, we continue to be committed to reducing our cash burn each year in order to reach companywide cash flow break even in 2028. For full year 2025, we expect free cash flow burn to be in the range of $225 to $235 million, an improvement, compared to $275 million for 2024. Our burn in 2025 will consist of approximately $200 million related to screening as we scale our Shield business and maximize our first mover advantage. Significantly, excluding screening, we expect the remainder of the business to burn approximately $25 million to $35 million during the year, and to reach cash flow break even in the fourth quarter of 2025. Finally, turning to Slide 25. We have a rich pipeline of catalysts across our business segments and are excited about the opportunities ahead. With that, we will now open the call to questions.
