Thank you, Greg. Good afternoon, everyone, and thank you for joining today's call. I'm Alex Johnson, President of CareDx's Patient and Testing Services, a member of the newly formed office of the CEO, along with Michael Goldberg, Chairperson of the Board; and Abishek Jain, CFO. I'd like to begin today's call by briefly covering the CEO transition we announced last week. Michael, Abhishek and I are aligned on the importance of executing against CareDx's strategic priorities and increasing shareholder returns, while the Board conducts its search for a new CEO. We have strong confidence in our leadership team and in the entire CareDx team to move the Company forward. For those of you whom I've not yet met, I have managed CareDx's largest business, the testing services business for the past two years. Prior to that, I had have responsibility for our lab products business as well as for business development. I have been incredibly fortunate to have worked with Michael on CareDx's IPO nearly a decade ago and with Abhishek for the past two years. I've also been privileged to work with Peter Maag, who many of you know as our former longtime CEO and current Board member for the better part of 15 years, dating from our time together at Novartis. On behalf of CareDx, we thank Reg for contributions to advanced transplant care during his tenure. We have a strong foundation for future growth, and we wish him the very best. Moving on to our third quarter performance. Today, I'm going to discuss our third quarter performance and results, discuss our decision to raise full year 2023 revenue guidance and finally, I will provide additional context around the transplant market environment and our patient advocacy efforts. In Q3, CareDx reported revenue of $67.2 million, an increase of 7% as compared to normalized second quarter 2023 revenue. Normalized Q2 2023 revenue results excludes the previously discussed financial impact of $7.8 million related to Medicare claims billing that were held over from the first quarter of 2023 and recognized in Q2 revenue. Our Q3 revenue for testing services came in at $47.8 million, growth of 5% compared to the normalized second quarter of 2023. Our patient testing services result grew 2% quarter-over-quarter to 38,400. After the period of uncertainty in the last few quarters, we now see a baseline being set in the testing services business as patient testing services volumes appear to have stabilized. We continue to be well placed in the transplant market, which is growing and is expected to continue to grow. Next, our digital transplant solutions business grew 33% year-over-year to $9.9 million driven by organic growth from our recent acquisitions. Some of our earlier acquisitions are beginning to scale nicely, helping us to drive both operating leverage and strengthening our moat. Our lab products business realized revenue of $9.5 million with year-over-year growth of 33%, driven by the success of our NGS-based portfolio. We are pleased with our improved performance, which is a result of an enhanced focus on driving revenue and improved efficiency in lab products, which has been an ongoing effort. We are pleased with our continued progress to actively reduce our overall expense base, which has helped mitigate the billing article impact lower full year revenue on our results. We will continue to look for ways to be more effective and efficient. Our adjusted EBITDA loss was $10.9 million in the current quarter as compared with normalized adjusted EBITDA loss of $18.1 million in Q2. Our goal is to be operating cash flow and adjusted EBITDA positive, and we are pleased to show demonstrable progress on this metric. We have confidence in our outlook going forward. As announced last week, we are raising guidance and now expect CareDx's full year 2023 revenue to be in the range of $274 million to $278 million, Abhishek will provide additional details during his remarks. In light of our strong cash position and belief that our stock is currently undervalued, we will continue to opportunistically pursue stock repurchases as part of our previously announced stock repurchase program. Next, I'll discuss our reimbursement coverage. In Q3, two previously announced catalysts came to fruition. We received Medicare coverage for AlloSure Lung and for heart care. Since its launch in 2021, AlloSure Lung has become increasingly valuable for lung transplant patient care. Heart care multimodality coverage was approved for surveillance. This has established a path for multimodality reimbursement that can be generalizable for other testing modalities in our portfolio such as AlloSure Kidney and UroMap. We continue to focus on increasing commercial payer coverage. For example, one national plan and three regional plans expanded coverage for AlloSure Heart to start at six months as compared to one year. We also gained coverage for two new regional plans for AlloSure Kidney. Moving to catalyst. When we have talked about catalysts in the past, we have highlighted our robust pipeline of clinical testing solutions, which is exciting, and we will continue to cover in future calls. Today, I want to highlight progress on a slightly different catalyst, one, which can facilitate greater payer coverage for AlloSure Kidney, and that is KOAR. KOAR, our kidney allograft outcomes registry has now completed the last clinical visits in Q3, and we will next move to data analysis. We anticipate a publication in 2024. KOAR has the potential to provide additional insights of payers, including Medicare, with respect to the clinical utility of AlloSure Kidney, including surveillance use in a wide variety of kidney patients. Our priority is to be good stewards of capital in this new environment. To invest in our strongest businesses and pipeline products that help us to deliver on our mission to bring innovation to transplant patient care while also creating the most value for investors in the short to midterm. Our strategy has not changed. We have nearly a quarter century commitment to improving transplant patient outcomes, extending long-term allograft survival and this will continue. We are confident that patients and investors can both benefit from the innovation and commercialization expertise of the CareDx team. Next, I want to address the conversations around GLP-1 drugs and their potential impact on kidney transplant volumes. There are about 550,000 dialysis patients in the U.S. and only about 25,000 kidneys transplants per year, with organ supply continuing to be the limiting factor. While GLP drugs have the potential to delay or may eliminate the need for dialysis in some patients, there's also the potential to help increase the number of dialysis patients eligible for a kidney transplant by improving their overall health or reducing their BMI. With respect to supply, it may be useful to note the potential impact of GLP drugs on the living donor pool, which is a major driver of kidney transplant volumes. Living donation volumes have the potential to increase beyond current trend lines as potential donors become healthier due to GLP-1s and feel more confident to donate their kidney. Before I turn the call over to Abhishek, I would like to touch on our advocacy efforts on behalf of transplant patients. We have been actively engaged in discussions with Medicare and HHS as well as helping to support legislative action and advocacy efforts to restore full patient access for Medicare beneficiaries. We have made good progress to date. On August 15, a bipartisan group of 14 members of Congress wrote to CMS Administrator, , Chiquita Brooks-LaSure to challenge CMS to reconsider these new limits on access to critical molecular tests that benefit transplant patients. In September, the Wall Street Journal Editorial Board published three editorials decrying the rollback in coverage for Medicare patients. Then in mid-September, MolDX held open meetings for public comment on the proposed LCD. CareDx was proud to have presented at both the MolDX Palmetto and the Noridian open meetings on molecular testing for allograft rejection. We and the broad transplant community will continue to fight for access to transplant innovation. With that, I'd like to turn the call over to Abhishek to discuss additional details on our quarterly results and outlook, and we'll go from there to Q&A. Abishek?
