Thank you, Chris. We executed well in the first quarter and although it's still early, we are beginning to see the benefits of our strategy to focus on areas where we expect to win as Chris mentioned earlier. So I'll now provide detail about our first quarter financial results and guidance for the second quarter and full year. Total company revenue for the first quarter of 2023 was $18.9 million and increased 24% compared with the same period of the prior year, primarily due to strong oncology revenue performance. Our oncology revenue, which includes revenue from pharma tests, enterprise and other customers was $15.9 million and increased by 35% over the same period of the prior year. The year-over-year increase of oncology revenue was driven mostly by the increase in volume from Natera, which accounted for half of our total revenue in the quarter. First quarter revenue from population sequencing, which includes the VA MVP was $3 million. Gross margin was 25.1% for the first quarter, compared to 28.1% for the same period of the prior year. The year-over-year decrease of 3% was primarily due to under absorbed overhead costs. Our lab expenses have increased over the last year and a half to support our growing oncology revenue volume and for background, testing cancer samples requires more labor and overhead compared with testing samples for the VA MVP. Over the next couple of years, we expect some gross margin variability due to fluctuating test volume, operating at lower utilization rates, providing diagnostic tests while we continue to increase our efforts to secure reimbursement, lost for our new facility and others. Longer term, we expect our gross margins to increase as we achieve scale by growing our oncology revenue. Operating expenses were $34.6 million in the first quarter and included a one-time non-recurring restructuring charge of $3.9 million associated with the reduction in force and closure of our China lab operation compared to $32.6 million for the same period of prior year. Excluding the restructuring charge of $3.9 million, our operating expenses were $30.7 million and decreased $1.9 million from the same period last year. R&D expense was $16.6 million in the first quarter, compared with $17.1 million for the same period last year. And SG&A expense was $14.1 million in the first quarter compared with $15.5 million for the same period last year. Net loss for the first quarter was $28.7 million compared with a net loss of $28.2 million for the same period of the year. The net loss per share for the first quarter was $0.61 and the weighted average basic and diluted share count was $46.7 million compared with the net loss per share of $0.63 and a weighted average basic and diluted share count of $45 million for the same period of the prior year. Now onto the balance sheet, we finished the first quarter with a strong balance sheet with cash and short-term investments of $148.9 million. In the first quarter, we used $18.7 million of cash due to the net loss, working capital needs and capital equipment purchases. We remain on track to reduce our 2023 cash use is down to approximately $75 million for the full year, which is significantly lower compared with $119 million used during the prior year. Now I'd like to turn to guidance. For the second quarter of 2023, we expect total company revenue to be $16 million to $17 million. Revenue from pharma tests, enterprise sales and other customers to be $13 million to $14 million, which is lower than the first quarter, primarily due to reduced sample volume from Natera and revenue from population sequencing of approximately $3 million. For the full year of 2023, there is no change to our guidance and we expect total company revenue to be $68 million to $72 million with oncology revenue from pharma, enterprise sales and other customers to be $59 million to $63 million. Population sequencing revenue to be approximately $9 million and expected to be recognized during the first three quarters. Net loss of approximately $103 million and cash usage of approximately $75 million, a reduction of $44 million from 2022, we look forward to updating you on our milestones as we make progress throughout the year. This includes obtaining reimbursement for NeXT Dx, showcasing evidence for NeXT Personal and completing the NeXT Personal clinical lab diagnostic test for commercial launch. Please stay tuned for future updates. And with that, I will turn the call back over to the operator to begin the Q&A session. Operator?
