Thanks, Shayla, and thanks everyone for joining us today. I am very excited to share our first quarter results, which were even better than we anticipated almost across the board. We delivered revenue of $82.4 million, 22% growth over the prior year, driven primarily by outperformance of Afirma and Decipher. Further, with our continued focus on financial discipline, we ended the first quarter with cash, cash equivalents and short-term investments meaningfully ahead of our projections at $178 million, roughly flat to the prior quarter, even with the seasonal use of cash that we anticipated. Behind this balanced approach to growth and capital preservation is our proven framework of identifying the specific clinical unmet needs, developing a test to address that need and securing the clinical evidence, reimbursement and guideline inclusion required to drive sustained market penetration. This approach is the force behind the performance of our Afirma and Decipher test and enables us to invest in our long-term growth drivers. This quarter, we delivered close to 12,500 Afirma tests for patients being evaluated for thyroid cancer, more than we anticipated, given that we had expected a greater impact due to seasonality, which is typical in the first quarter. We saw positive growth trends across both our ordering base and orders for existing provider. On the reimbursement front, we secured four new payer contracts, making the test an in-network benefit for over 4 million additional health plan members. In addition to the outstanding work of our commercial and reimbursement teams, I'm excited to share that as part of our initiative to enhance our best-in-class Afirma tests, we recently launched the addition of TERT promoter mutation testing to the Afirma report. There have been several studies published recently that correlate the presence of the TERT promoter mutation to a high risk of malignancy as well as highlighting that such mutations co-occurring with the BRAF V600E variant are associated with a poor prognosis. Given the value of these insights for informing patient care, such as whether more aggressive surgery or treatment is wanted, our team works hard to develop a high-quality DNA assay that allows us to reliably determine the TERT mute -- promoter gene mutation status for patients with suspected or diagnose thyroid cancer to further empower physicians to optimize clinical decision-making. We believe that product enhancements such as this, along with the work we've done to improve the customer experience and to streamline ordering will continue to benefit Afirma's performance in the coming quarters. Given this as well as our strong first quarter results, we now expect the bolster growth rate for Afirma in the high single-digits for the full year. Turning to Urology. We continue to expand on the budding evidence surrounding the Decipher Prostate Test, further helping to establish the test as a new standard of care. At the American Neurological Association Annual Meeting earlier this week, multiple abstracts were presented focusing on Decipher Test, particularly exciting with data from two large Real-World data sets encompassing more than 100,000 men with prostate cancer, which reinforce the clinical utility of our tests. In the first study, researchers paid data from the National Cancer Institute their database with patients who had undergone Decipher Prostate Testing and found that use of our test was independently associated with a two-fold increase in conservative management among those with favorable risk disease. In the second study, over 90,000 Decipher Prostate Test results were linked to electronic health and claims data to demonstrate the decipher score at initial diagnosis was independently predictive of risk of metastasis, and after radical prostatectomy was predictive of both biochemical recurrence and metastasis. In addition to the data presented at AUA, we published a number of studies last month that further advance the clinical utility evidence for the Decipher Prostate Test. The first study published in European Urology Oncology found in a cohort of over 4,000 patients, the Decipher Prostate could help better identify those patients with early micrometastatic disease who may benefit from treatment intensification. This study adds to growing evidence around the use of decipher prostate to help inform treatment decision-making in initial diagnosis. Additionally, new data from an analysis of an NCI-sponsored Phase 3 study published in the International Journal of Radiation Oncology Physics, known as the Red Journal, choose the Decipher Prostate Test can help physicians more accurately categorize personal risk and select appropriate treatment for men with intermediate risk prostate cancer. This is important because prostate cancer deemed intermediate risk by NCCN guideline is the most heterogeneous all risk groups in the disease and a wide variety of treatment is available. Of note, this randomized study in which patients were followed for nearly 13 years, is the first to validate any gene expression biomarker in the intermediate risk patient population. The attainment of Level 1 evidence the validation of our test in the most recent NCCN guidelines, along with the stellar execution by our team and our differentiated Decipher Grid report led to Q1 Decipher prostate volume of more than 12,500 techs. Like Afirma, this growth was also driven both by strong adoption from new ordering position, as well as higher volumes from existing accounts. Building on the framework, we've established with a firm decipher we are making good progress on our long-term growth drivers. Decipher patient enrollment for NIGHTINGALE, the clinical utility study for our Percepta Nasal Swab continues to progress well, demonstrating the potential for our novel noninvasive tests to help guys positions netted for patients with potentially malignant lung launches. We look forward to presenting expanded preliminary data on the familiarity phase of the trial, which enabled investigators to learn how to incorporate the test into patient management in advance of the clinical utility trial at the American Thoracic Society, or ATS International Conference later this month. The global launch of our test menu to patients outside the United States is another key long-term growth driver for Veracyte. Our current IVD product offering, Prosigna for breast cancer patients had a record quarter, delivering close to 3,000 tests, demonstrating traction and adoption supported by clinical evidence. With the submission of our Envisia Genomic Classifier to European regulators in December 2022, we are now responding to feedback from the notified body -- in the meantime, we continue to build clinical evidence for Envisia and are looking forward to the presentation of abstract at ATS, demonstrating the test impact on patient management and its ability to predict disease progression in patients within interstitial lung disease. We believe our focus on evidence generation will help drive adoption of NVIDIA globally, bolstering the LDT in the US, while gaining important KOL support in Europe in preparation for the international launch of the IVD. We're also making good progress building out our broader menu of diagnostic IVDs to US market with the type of prostate expected to permission in 2024 and our nasal swab expected for submission in 2025. While our biopharma business is facing significant headwinds over the course of this year, given the impact of a sizable customer pulling back on planned spending and the current macro environment, we continue to advance our unique multi-omic offerings. We were pleased to share three abstracts and host a Spotlight Theater at the AACR Annual Meeting, highlighting our distinctive set of assets to help biopharma partners that all points along the drug development process. We are continuing to build out our pipeline of new customers to fuel the long-term growth prospects of this business. As I laid out on our call last quarter, one of the strategic focus areas for 2023 is to identify new opportunities to expand our testing menu beyond our currently available products and the pipeline I outlined. As part of these efforts, we held our first annual discovery day in April, bringing together our R&D, medical, clinical and commercial teams from across the globe to imagine the future for oncology diagnostics and Veracyte's important role as a leader in shaping that future. I'm extremely pleased with the work our teams are doing on this front and our investments to drive the next phase of growth for the company. Before I close, I'd like to highlight the publication of our inaugural environmental, social and governance report earlier this week. This ESG highlights how our mission and values are deeply embedded in our business and demonstrates not only our dedication to transforming patient outcomes all over the world, but also our commitment to our shareholders, employees, business partners and other stakeholders. I'm pleased to provide transparency into our ESG efforts and I'm excited to build on the foundation we late to further advance our program. In summary, Q1 was a fantastic quarter marked by solid execution across the team. We're excited about our progress to date and our clear focus for the future. With that, I will now turn to Rebecca to review our financial results for the quarter and updated expectations for 2023.
