Thank you, Greg. Good afternoon everyone, and welcome to CareDx' fourth quarter and full-year 2023 Earnings Conference Call. CareDx ended 2023 in a solid growth and market leadership position after a challenging start to the year. Our team spent the last year addressing the complexities associated with the billing article reconfiguring the company to adjust to the Medicare changes to coverage and fighting to restore patient access to transplant innovation. Before we move into the details of the quarter and the year, let me step back for a moment and offer a bit of perspective. We are still in the early stages of a $6 billion market opportunity to health care for some of the highest need patients in the U.S. health care system. Transplant patients in the U.S. are experiencing incrementally improved short-term outcomes, but are still far away from having their newly transplanted kidney, harder lung lasts as long as it should. We continue to believe that effective care remains truly understanding transplant patient management. And this requires focus from our entire team working closely with some of the world's best clinicians, researchers and transplant centers. Our ability to successfully lead and execute in this growing market in the face of complexities associated with the billing article revisions is reflected in our results. Last year, we executed deliberately, quickly and with high impact as demonstrated by our performance. We reduced our cost structure and stabilized our revenue base. Consistent with our pre-announcement, we reported full-year revenue of $280 million, exceeding the high end of our updated guidance. We have regained our growth footing in our testing services business with patient test volumes up 4% quarter-over-quarter, an increase for the second sequential quarter in a row. We delivered about 40,000 tests in the fourth quarter and patient testing services volume was approximately 165,000 patient results for the full-year. We continue to make progress in driving our innovations into clinical practice. This year, we witnessed strong support from leading medical societies and from patients, advocating for access to transplant molecular testing, including AlloSure and AlloMap, underscoring the pivotal role our innovations play in improving transplant patient care. In 2023, two new Medicare coverage approval supported the clinical value and market opportunity of our innovation pipeline. AlloSure Lung was the first donor-derived cell-free DNA approved for coverage by Medicare for lung transplant patients. And with the approval of heart care, in August 2023, our clinical approach of multimodality testing was confirmed by CMS. This approval defines a reimbursement pathway for our differentiated product portfolio, one that can leverage our rich pipeline of innovation to help improve patient outcomes. On the commercial payer side, we saw good progress. We ended the year with an additional 15 million covered lives. We expanded existing coverage for 31.5 million lives in our cardiothoracic business, primarily by adding coverage in the first six months post-transplant for AlloMap Heart. Looking at our other businesses, we are pleased with the double-digit growth in both our patient and digital solutions and lab products business lines, representing year-over-year growth of 29% and 15%, respectively. Before moving on to 2024, I will touch on our recent Pat litigation news. As we mentioned in our statement following a jury verdict in late January, CareDx was assessed damages of approximately $96 million. We intend to seek judicial review of the jury decision and monetary damages. We expect there to be active briefing on this matter at least through Q3 2024 in the District Court. The matter would then be subject to appeal to the Federal Circuit. Precise timing would be speculative, but we would expect any resolution for the patent litigation to be a multiyear, multistep process. Looking forward to 2024. In our testing services business, the focus is on strategic profitable growth, continuing to grow patient testing volumes and market penetration for AlloMap and AlloSure, while expanding reimbursement and coverage. There is a significant opportunity to gain coverage for nonreimbursed tests. This year, we will continue to invest in multicenter, purpose-driven studies to help secure additional reimbursement coverage. As mentioned last quarter, KAOR, our Kidney Allograft Outcomes Registry completed the last patient clinical visits, and we are now finalizing our data collection and monitoring. KAOR was designed to demonstrate the clinical utility of AlloSure in a variety of outcome, and we continue to expect a publication this year. We also have other unique opportunities to publish evidence that can influence payer coverage policies by working with leading researchers who have had extensive experience with AlloSure Kidney. In heart, we anticipate an interim readout for our ongoing Surveillance HeartCare Outcomes Registry or SHORE. The data from patient encounters in the early years of SHORE have been collected and monitored. We are now working towards publication of an interim readout with the twin goals of supporting the utility of multi-modality testing and heart care coverage beyond year one. We expect publication in 2024. These studies are expected to generate the evidence that, along with the build-out of our revenue cycle management infrastructure, such as commercial payer coverage and billing appeals process, will support an improved rate of reimbursement. In our Patient and Digital Solutions business, we aim to further increase the adoption of our portfolio offerings in 2024. Over 70% of transplant centers in the U.S. use one or more of our digital solutions. As we first shared last month, we have now started to roll out a new platform, which enables greater uptake of CareDx services. The platform called CareDx Pro is embedded within a transplant centers electronic medical record workflow. This allows clinicians and administrators to have a single interface to access our digital health and SaaS solutions as well as for clinicians to seamlessly order and view test results for AlloSure, AlloMap and HeartCare. Our growing lab products business is global. We have a strong portfolio, and we'll continue to expand the business to a new transplant laboratories worldwide with best-in-class kitted products using NGS and QPCR technologies. Our market leadership for NGS HLA typing through our AlloSeq Tx line and broad geographical footprint allows us to benefit from scale leverage as our products business grows further. From an operational perspective, we'll remain focused on thoughtfully managing our cost structure and investments. You heard this during our Annual Investor Day last month, and it is worth repeating. This commitment underscores the dedication of our leadership team to driving growth and value for investors. We have taken multiple actions to reduce costs, including a recent Q4 action to streamline even further. You'll see us continue to take steps to manage our near-term cost and COGS as we drive towards profitability. CareDx is taking a disciplined approach to investments that support our clinicians, patients and employees and deliver shareholder value. Finally, I would like to touch on our advocacy efforts on behalf of the transplant patients. We and our coalition partners continue to be actively engaged in discussions with HHS and CMS, while we support patient advocacy efforts to restore full access for Medicare beneficiaries. The transplant community has made substantial progress. Some of you may have seen the honor of the gift efforts in Washington, D.C. in early December, where hundreds of transplant patients, physicians and advocates made publicly on Capitol Hill to stop the recent rollback in Medicare coverage. Notable speakers of the press conference included Senator [indiscernible], former Speaker of the House Newt Gingrich and Reverend Al Sharpton, which shows the wide-ranging bipartisan nature of the concerns here. We and the broad transplant community will continue to fight for access to transplant innovation in 2024 and beyond. In fact, as recently last Friday, the Wall Street Journal published their fourth powerful editorial since September, highlighting the patient access issue for transplant tests and the coverage disparities for Medicare patients. We are encouraged by our momentum as we enter 2024. Our team is laser-focused on executing our plan. We are building on the testing services revenue baseline set in the second half of '23, expanding patient access to our innovative portfolio across all three businesses and expediting our journey back to profitability. With that, I will ask Abhishek to share more details on our results for 2023 and our outlook for '24. From there, we will go to Michael Goldberg, our Board Chair for an update on our CEO search before moving into the Q&A. Abhishek?
