Thank you, Chris and welcome everyone to Biodesix first quarter 2021 earnings conference call. We were pleased with our operating and financial performance in the first quarter and believe we're off to a solid start in 2021. Beginning with a high-level overview of our financial performance, we reported record revenue of $28.9 million in the quarter, which represented year-over-year and sequential quarterly increases of 466% and 7% respectively. Robin will go into more detail, but this comes on the heels of another record quarter from our COVID-19 testing services revenue, which grew 8% over the fourth quarter of 2020. As many of you know, our COVID-19 offering was developed in response to the public health emergency and has been driven by the need for quality rapid testing that could be delivered quickly and reliably. We were compelled to respond to the pandemic and our COVID-19 testing services quickly became a strong source of revenue growth for Biodesix. While the overall rate of testing in the US is tapering off due to the availability of vaccines and readily available retail at-home testing options, we continue to work to support communities both locally and across the country by expanding our WorkSafe COVID-19 Testing Program. Biodesix continues to perform on-site rapid antigen testing for schools, athletics, and employers to quickly identify potential cases that are then reflexed to our highly accurate PCR testing for confirmation and validation. Over the last year, we nimbly addressed the evolving challenges of the pandemic and are proud that we continue to do so. Recently, we announced a partnership with GenScript Biotech to conduct performance verification in our laboratory and commercialize its cPass SARS-CoV-2 neutralization antibody test. This is the first and only surrogate neutralizing antibody test with FDA EUA authorization. The current vaccines are highly effective at generating antibodies against the viral spike protein when administered as recommended. However, despite significant research and clinical advances made to combat the SARS-CoV-2 virus, the emergence of new variants and community outbreaks are of continued concern. Neutralizing antibodies may specifically block the interaction between the receptor binding protein on SARS-CoV-2 and the host cell's membrane receptor protein, thereby preventing infection of the cell by the virus. In essence, the test has the potential to identify individuals who may have antibodies capable of preventing the virus from infecting the cells. We believe that the cPass test could be important in understanding long-term protective immunity to SARS-CoV-2. This test is currently available for research and biopharma services work, and announcements about the commercial launch of the test in our WorkSafe program will be forthcoming. In many respects, our role in the global pandemic has increased the public awareness of Biodesix and who we are, a trusted partner that the world can rely on for data-driven diagnostic solutions that improve patient outcomes, lower healthcare costs, and deliver results quickly. Biodesix remains focused on our core business, which includes solving complex diagnostic challenges in lung disease and for our biopharma partners. This focus represents a large US target addressable market that we estimate is greater than $29 billion. We utilize multiple technologies, including genomics, transcriptomics, proteomics, and radiomics, and leverage our proprietary AI-based diagnostic Cortex platform to discover innovative diagnostic tests for clinical use. The company has six diagnostic tests commercially available, each of which intends to solve complex diagnostic challenges in lung disease and provide best-in-class turnaround times while reducing costs by eliminating unnecessary tests and procedures. Our Nodify XL2 and Nodify CDC tests are used to assess the risk of lung cancer for patients presenting with lung nodules and to help physicians identify the most appropriate treatment pathway. Our GeneStrat and VeriStrat tests are ordered by physicians following diagnosis of lung cancer to measure the presence of mutations in the tumor in addition to the state of the patient's immune system to establish the patient's prognosis and help personalize treatment decisions. In our lung diagnostic testing, we were pleased to see our first quarter revenue increased both year-over-year as well as sequentially above the fourth quarter of 2020. This business does, however, continue to be adversely impacted by the global pandemic as pulmonologists have redirected time and efforts to treat patients with COVID, and they have limited clinic volumes. However, this quarter we did begin to see a shift that suggests pulmonologists are beginning to see more non-COVID-19 patients and expect this to continue throughout the course of the year barring additional spikes and changes in the pandemic. As we focus on the recovery and our growth expectations, we continue to invest in our sales infrastructure and remain on track to double the size of our direct and dedicated sales force in 2021. The expanded sales force will better allow us to reach more physicians and provide them with a portfolio of tests to provide personalized information on their patients. This information will aid the physician in making educated decisions to direct the right patient on the biopsy or surgery and help many more avoid unnecessary interventions and guide treatment decisions. One of the most exciting recent developments is our new liquid biopsy next-generation sequencing test. The test was shown in a recent publication to have an unprecedented 72-hour turnaround time, which is significantly faster than the seven to 14 days it takes for other NGS tests on the market. Time to treatment for patients with cancer is critical, and we strive to provide reliable blood-based tests as quickly as possible to support our physicians and their patients. The NGS test will complement the GeneStrat ddPCR test and VeriStrat proteomic tests currently offered with the expanded coverage of broader molecular markers. The 52-gene NGS test will be intended for use in patients diagnosed with advanced, late-stage, or recurrent cancer while the targeted cart GeneStrat ddPCR test measuring six genes individually can be used for identification of the select mutations in all stages of the disease and for treatment guidance, recurrent monitoring, and detection of the development of resistance mutations over time. Over the last year, we've cut the turnaround time of GeneStrat and VeriStrat in half from 72 hours to 36 hours, furthering our commitment to provide high-quality test results as quickly as possible. The NGS test has been available for research and clinical trial use since 2018, and we plan to launch the test for commercial use in the first half of 2022. We'll provide more details in the months leading up to commercialization. We also continue to support the use of our diagnostic tests by adding to the body of evidence demonstrating their utility and value. This remains a key component of our business and drives both clinical adoption and reimbursement. In April, we announced three abstracts for multiple clinical studies on our primary immune response and various tests, which were presented at the 2021 Association for Cancer Research Annual Meeting. These abstracts reflect our commitment to continual research and address the utility of physicians utilizing blood-based proteomic testing as an approach to support their treatment decisions with the ultimate goal to improve patient outcomes. We also partner with academic institutions and biopharma technology and diagnostic companies to provide research, clinical trial testing, and new companion diagnostic discovery and validation services. With significant ongoing partnership and research activities of Biodesix, we will continue to strengthen and broaden our position in the market executing a deliberate patent strategy. We recently announced the issuance of two new patents that enhance our ability to develop blood-based immunotherapy and pipeline testing strategies. Patents have historically driven the biotechnology industry forward, but conversely have become more difficult than ever to obtain. Our recent issuances in this fast-paced diagnostic sector further improve Biodesix ability to develop and commercialize rapid and accurate diagnostic testing to support physician treatment decisions and strategies for their patients. Now, let me turn the call over to Robin to discuss the first quarter financial performance.

Thank you, Scott. Our first quarter revenue was $28.9 million compared to $5.1 million for the first quarter of 2020, representing an increase of 466% and an increase of 7% over the $27.0 million reported in the fourth quarter of 2020. Year-over-year and quarter-over-quarter revenue improvement continues to be fueled by our successful entry into COVID-19 testing services, which has enabled us to diversify our portfolio during a period of expected downturn resulting from the global pandemic. Our COVID-19 testing services revenue was $23.2 million in the first quarter 2021. Since this business began in the second quarter of 2020, there is no meaningful year-over-year comparison. However, sequentially, our COVID-19 testing revenue grew 8% over the fourth quarter of 2020. The increase in revenue was driven by volumes from existing and new customers. We continue to expect meaningful contribution during the second quarter of 2021. While COVID-19 testing services played an important role in our overall revenue growth during the quarter, we are particularly pleased with the improved trends in lung diagnostic testing. Our lung diagnostic revenue was $4.0 million in the first quarter of 2021, compared to $3.6 million for the first quarter of 2020, representing an increase of 10% and an increase of 8% over the $3.7 million reported in the fourth quarter of 2020. As you know, our primary call point in lung diagnostic testing is the pulmonologist, who have been significantly impacted by the pandemic as they have been pulled into ICUs and ERs to treat patients with COVID-19. Although we expect pulmonologists to continue to be impacted by any ebbs and flows in COVID-19 case volumes, we are encouraged with the progress this quarter, and particularly the bounce back in volumes we saw in the month of March. Overall, we believe the recent volume trends represent a leading indicator of the recovery from the pandemic. As the vaccine rollout continues, and more pulmonologists return to their normal workflow seeing patients, we would anticipate an increased need for lung diagnostics that we believe will benefit our testing business throughout the course of 2021, though potentially offset by the spikes of the virus and hotspots around the country. Turning to biopharma services, first quarter 2021 revenue was $1.7 million compared to $1.5 million for the first quarter of 2020, an increase of 12%. Biopharma service revenue declined 12% sequentially from $1.9 million in the fourth quarter of 2020. As we have said, this particular business can fluctuate quarter-to-quarter due to a number of factors, including contract timing and the impact of COVID-19, which has resulted in a global slowdown of clinical trials. However, we expect full-year 2021 revenue results will represent growth over fiscal 2020. Overall, biopharma services remain a significant long-term opportunity for Biodesix as clinical trials begin to ramp back up. Moving down the P&L, direct costs and expenses for the first quarter of 2021 were $18.2 million as compared to $1.6 million for the first quarter 2020 and $14.7 million for the fourth quarter 2020. The increase in direct costs and expenses was primarily driven by costs associated with our entry into COVID-19 testing, as well as the release of our Nodify CDT test in March of 2020. Overall, our COVID-19 testing continued to provide strong revenue and gross profit dollars to offset the impact of the pandemic and perhaps more importantly, enables us to invest in lung diagnostic testing and biopharma services. Gross margin percentage in the first quarter 2021 was 37% versus 69% for the first quarter 2020 and 46% for the fourth quarter 2020. The decrease in gross margin percentage for all periods presented is driven primarily from our entry into COVID-19 testing, as those margins are lower overall than the margins for our lung diagnostic testing. While the COVID-19 testing services gross margin percentage is lower than that of our other tests, it does provide strong revenue and gross profit dollars contributing to the business. We continue to see strong margins in our lung diagnostic business consistent with pre-pandemic levels and expect that to continue during the recovery from the pandemic. Operating expenses, excluding direct costs and expenses, for the first quarter of 2021 were $16.2 million compared to $11.9 million for the first quarter of 2020, an increase of 36% and 8% compared to $15.0 million for the fourth quarter of 2020. The increase in operating expense in the first quarter of 2021, as compared to the first quarter of 2020, was driven primarily by higher selling, marketing, and G&A expenses, including investments in the expansion of our salesforce, which increased to $11.9 million compared to $8.1 million in the first quarter of 2020. The increase in selling, marketing, and G&A is attributable to an increase in variable compensation associated with stock-based compensation from our first quarter 2021 option grants, our bonus to equity incentive program, an increase in headcount and public company costs. First quarter 2021 operating expenses increased by approximately $1.2 million compared to the fourth quarter 2020, which was primarily attributable to the change in the fair value of contingent consideration. Research and development costs for the first quarter 2021 were $3.3 million, as compared to $2.9 million for the first quarter 2020 and $3.1 million for fourth quarter 2020. The overall increase in R&D was attributable to an increase in internal costs primarily associated with increase in headcount as we scale R&D and add new products to our pipeline following our IPO. After beginning the expansion of our commercial organization, launching multiple new clinical trials and investing in our pipeline. The net loss for the first quarter 2021 was $7.0 million as compared to a net loss of $9.7 million for the first quarter of 2020 and $4.5 million for the fourth quarter 2020, including our first quarter net loss were non-cash stock-based compensation charges of approximately $1.8 million and $728,000 in non-recurring costs associated with the loss on extinguishment of our 2018 term loan. Finally, turning to the balance sheet, we ended the quarter with $55.3 million in cash and cash equivalents, a reduction of approximately $6.8 million, primarily as a result of an increase in working capital partially offset by cash provided by financing activities of approximately $5 million. During the quarter, we enhanced our financial flexibility through a new $30 million term loan and extinguished the outstanding borrowings of $25.9 million under the company's prior term loan, with the remaining proceeds of approximately $4 million available to enhance existing liquidity for general corporate purposes. The transaction will provide Biodesix with additional operational and financial flexibility, including an interest-only period until February 2024, as we achieved the trailing 12-month revenue milestone of $65 million as of March 31, 2021. In addition, the net proceeds along with the benefit of extending our interest and principal payments will enable Biodesix to continue the growth of our commercial organization and expansion of our clinical pipeline. Looking forward, due to the rapidly evolving nature of the pandemic, testing strategy, vaccinations and the resulting impact on healthcare in the US, we are not providing revenue or earnings guidance at this time. We do, however, expect year-over-year revenue growth, with our gross margin percentage in the first half of the year suppressed by the strength of our COVID-19 testing activities, and an improvement in our gross margin percentage occurring in the latter half of 2021 as the expansion of our sales teams further momentum and generates growth in our lung diagnostic testing. We expect that COVID-19 testing revenue will be highest in the first quarter with decreasing revenue throughout the year, subject to our ability to enter into further testing services such as the cPass COVID-19 Neutralization Antibody Detection test. However, we will continue to provide COVID-19 testing services to our healthcare, schools, and other employer group partners and expect to evolve our offering as the country continues to move forward. And we've learned to live with COVID-19. While we expect to increase our overall operating costs in 2021 due to the execution of our growth strategy and investments in bringing new products to market, we are maintaining a disciplined focus on costs and are continuing to evolve our offering with the future launch of the cPass total Neutralization Antibody Detection test and our new NGS test. Now, I will turn the call back to Scott.

Thanks, Robin. So before opening the call up for questions let me do a quick summary. Our liquidity position remains strong and provides us with the financial flexibility to achieve our business growth objectives. We were thrilled with our financial performance in the quarter and most encouragingly, we're seeing early signs of pulmonologists returning to pre-COVID-19 levels. Barring another wave, we expect this trend will drive our core lung business for the remainder of 2021. We continue to enhance our clinical dataset to support both on-market and pipeline products, and are thrilled to have announced two new tests, the cPass COVID-19 Neutralization Antibody Detection test and our new 72-hour turnaround time liquid biopsy next-generation sequencing test. The latter expands our comprehensive portfolio of products focused on solving complex diagnostic challenges in lung disease. We're also making progress expanding our salesforce by doubling our salesforce over the course of this year, calling on pulmonologists which will allow us to reach more physicians and better leverage improving trends in our growing product portfolio. Lastly, I want to close with a thank you to all Biodesix teammates, whose effort, dedication and daily contributions make it possible to achieve our ambitious mission. With that, I'll turn the call over for questions.

Thank you. Our first question comes from the line of Tejas Savant with Morgan Stanley. Your line is open. Please go ahead.

Hey, Scott, Robin, good evening. Maybe I'll start off here with one question in the 52 Gene Liquid Biopsy panel. Scott, can you give us a sense of what remains to be done between now and commercialization in the first half of next year? Are there plans to add sort of additional markers like TMB and MSI to the panel pre-launch? And then, as a follow-up, how do you see this panel fitting into the relatively crowded landscape with larger incumbents who already have reimbursement in place, and also, visually your own sort of GeneStrat and VeriStrat workflow?

Yeah. Thanks, Tejas, great question. As you might recall, we stated that GeneStrat is complimentary to the other NGS tests that are currently on the market. And we expect the same with our own NGS tests. Reminder for everybody, GeneStrat is a small, actionable offering of guideline-recommended targeted mutations, and the NGS test is going to be a broader panel for additional targeted and rare mutations. We believe this combination of two tests allows physicians to utilize at all stages of lung cancer and through the full patient journey including both diagnosis, prognosis, and even later lines of treatment selection. On the first part of the question, in terms of our development timeline, obviously, we're working towards commercialization and regulatory submission. With that, many things in our product development timeline are consistent with prior product launches, so just really ensuring that we're ready as a business to scale and ramp the test. I'll turn it over to Robin. She may want to comment on reimbursement and our plans there.

I can also comment on the MSI and TMB portion of it. So right now, the current clinical data that we've seen on MSI and TMB is predominantly in tissue. However, as that starts to move and evolve into the liquid space, we would absolutely love to add those. From a reimbursement perspective, yes, it is definitely a crowded landscape. But I also think there's benefits there too. This is not something that will be brand new for payers; there's an established set of criteria. It’s about discussing with them how the test works and providing the statistics for the test. So yes, while it's crowded, that also provides some benefits as well.

Got it. Very helpful. And then, one on COVID testing. I know, I think Robin you mentioned in your prepared remarks that you do expect sort of a sequential decline through the rest of the year here. Is there anything beyond that in terms of color that you can share? I mean, obviously, $23 million is sort of the high watermark, but do you expect to be in the single-digit sort of COVID contribution range by the fourth quarter here? Or are you just don't have that kind of visibility yet? And then, secondly, in terms of the neutralizing antibody testing launched in mid-2021, can you help us think through how significant of a contributor that could be?

Sure. I think with everything in the pandemic, it's really hard to predict how this will evolve and change. I think the one thing we absolutely can predict is that it will continue to change. And I think that's one of the things that we excel at is evolving our offering, changing and adding services, adding the neutralizing antibodies. So with the visibility we have now, yes, we continue to think that the COVID testing will decrease, but do anticipate that there is demand that recurs into the fall, particularly around schools, travel events, things like that. And so, while we are still anticipating the decline, we are not in any way giving up on COVID testing. There’s still a huge need and we're continuing to pursue opportunities. As for the neutralizing antibody test, that one really is a big question mark right now, because we're all still trying to figure out where and how it fits.

Got it, got it. Helpful. And then, one on COVID testing. I know, I think Robin, you mentioned in your prepared remarks that you do expect sort of a sequential decline through the rest of the year here. Is there anything beyond that in terms of color that you can share?

Sure. I think with everything in the pandemic, it's really hard to predict how this will evolve and change. I think the one thing we absolutely can predict is that it will continue to change. I think that’s one of the things that we excel at is evolving our offering, changing and adding services, adding the neutralizing antibodies.

I understand. That’s helpful. For my final question regarding the base business, you mentioned seeing an improvement in March. Could you provide some details on current patient volumes among your pulmonologist community compared to pre-pandemic levels? Is it around 80% back to normal, or perhaps even higher? Additionally, could you discuss the trend from January to February, and how things have progressed into March and April?

We're pleased with the state of the recovery and seeing improvement over time. January was an interesting month with a massive spike; February, an interesting month with a massive snowstorm. We’re pleased with how we're seeing recovery in March and April. It's hard to compare really pre-pandemic to current, mostly because we had really just launched XL2, and then launched CDT in March literally days before we sent everybody home, so it’s a little difficult to compare the two.

Got it? Fair enough. Thank you.

Thank you, Tejas.

Thank you. And our next question comes from the line of Brian Weinstein with William Blair. Your line is open. Please go ahead.

So sticking to the core business here for a second, obviously there's a backlog of patients that are going to be coming through that are going to need to have some sort of workup done, which would mean that your Nodify franchise seems like it's in a very good position to be able to leverage the capabilities that it has and make the workflow more efficient. So can you talk about the sales and marketing activities that you guys are undertaking to amplify that message to your customers and any early read where you have your salesforce back in place, how that message might be received?

Yeah. Thanks, Brian. Great question. As you recall, post-IPO, we stated that our 2021 goal was to double the size of our direct and dedicated sales force, going from 24 sales reps to 48 sales reps. So first and foremost, we continue with that plan and are progressing nicely. We're very encouraged with the quality of teammates that we've added and their ability to onboard rather quickly. To your other point about kind of the recovery, yes, pulmonologists are seeing less and less COVID patients and are returning back to what one could describe as a kind of normal business cadence. But there is this described backlog of patients, which makes a ton of sense, knowing that we've not seen patients the way we would have prior to the pandemic. The real question is vaccination schedules comfort of those patients to come into clinic. We started with our biggest concern being the physician, ensuring the physicians were protected, not just physicians, but their healthcare staff. Now that they've all been vaccinated, ensuring that this patient population is vaccinated is key and critical. Our dialogue with pulmonologists is that they are seeing patients return to in-person. We know that also benefits us, as much as we may never return to a pre-pandemic environment. Because of COVID, being able to meet face to face, a physician consulting a patient, not through telemedicine still has a place. Our sales reps are there. They're conducting in-person sales calls. Yet at the same time, we monitor the virus, we monitor spikes, and we still collaborate with pulmonologists to ensure that we're welcome coming into their clinic and that we're mindful of any potential exposures they may have had.

Okay, thank you. And then on the liquid biopsy NGS test, you talked about the unprecedented 72-hour turnaround time versus 7 to 14 days. Can you give us any insight into what you have done to allow that to take place recognizing that some of it is probably trade secret, but just generally speaking, what is it about the way that you guys are operating that allows you to show that turnaround time? Then as a follow-up question on that, these products are available for research and clinical trials, I think you said since 2018. So why is now the right time to launch? Is that tied to the improvements in turnaround time? Thank you.

Yeah, thank you, Brian. Great question. You know, I’ll start with turnaround time for GeneStrat. We've discussed how opportunistic we've been at Biodesix and how we really have evolved during the pandemic. One of the benefits of proceeding with COVID testing and utilizing and leveraging our ddPCR platform is that we've been able to expand our laboratory; we also are running 24/7, which allows us to decrease that turnaround time. And you may recall GeneStrat has improved by 50% during the pandemic, so we went from 72 hours down to 36 hours of GeneStrat. That really is leveraging the additional resources team and laboratory capacity that we have. Related to the NGS product, you highlighted a 72-hour turnaround time on an NGS product is unprecedented. You're correct; some of that is trade secrets. And you were also correct that we did introduce that for biopharma research in 2018. Many of those partnerships and collaborations gave us additional experience and opportunity to optimize that offering. So we're really excited about that. We think it matters. We know that we're dealing with patients that have cancer, and patients that have cancer, the one thing that they don’t always have an abundance of is time. Our ability to return those actionable insights as quickly as possible makes a difference.

Thank you for the answer, Scott.

Thanks, Brian.

Thank you. Our next question comes from the line of Sung Ji Nam with BTIG. Your line is open. Please go ahead.

Hi. Thanks for taking the questions. So just on the liquid biopsy next-gen sequencing assay, could you talk about your go-to-market strategy there? Do you anticipate leveraging the existing sales force and the sales channels and also with the RUO users, since 2018, or could they be kind of some of the early adopters of this platform?

Hi, Sung Ji. Thanks for the question. I'll go in reverse order. When it comes to our biopharma partners, unfortunately, we haven't disclosed who those partners are at this time. But yes, it's safe to say that those partnerships, those collaborations, and those relationships do provide great insight for us. And we're able to apply that to our commercialization strategy. We've not yet disclosed our commercialization strategy because we've announced that we will launch this mid-2022. We plan on developing that plan and rolling that out as we progress through the year. So much more information to come there. The good news is, because of our existing Salesforce footprint, relationship, and experience selling GeneStrat, this really is an opportunity for them to continue to leverage the relationships that they have built on the awareness of GeneStrat and VeriStrat to ensure that we can provide the treatment guidance that others strive to.

Great. That's super helpful. And then just on the CDT test neutralizing the antibody, could you talk about the go-to-market strategy there? Are you targeting largely the biopharmaceutical companies that have these vaccines under development or those that have developed the vaccines? And also, if you could talk about T-cell profiling and other types of characterization, right, in terms of patient response and monitoring to the pathogens as well as to the vaccines?

Yeah. Great question, Sung Ji. Thank you. Because we just had the webinar and just announced that we'll be commercializing this test this summer, as you can imagine, we're getting a lot of input, a lot of inquiries, and numerous conversations are occurring as we speak. For us, this really has been about being a one-stop shop. As you recall, early in the pandemic, we announced that we had partnered with Bio-Rad to launch the ddPCR test. Then shortly thereafter, we announced our collaboration with Bio-Rad to introduce our first antibody test. Then we continued to pivot, where we provided support, surveillance, and monitoring for antigen testing that would then reflex to high-quality ddPCR testing. We really have viewed ourselves as a comprehensive COVID solution provider, a one-stop shop if you will. So adding this into the portfolio, we think positions us exceptionally well to continue to provide those personalized insights that individual institutions may have. With that, our approach has been consistent. Anyone that we've provided testing solutions and support to thus far, we've reached out to them to introduce the neutralizing antibody tests. We’ve begun answering the questions and formulating a plan by which this may provide meaningful insights to them, whether it's a return to work strategy, travel or international travel, or then building upon some of our sports and athletics and educational services that we've offered. Just ensure that they have the ability to utilize any one of these tests to set them up for success, whatever that means to them or however they define that. Much more to come with that in the coming weeks and months. When we do make that commercially available, we will disclose that and start providing greater insights into the feedback we're receiving. But if you had an opportunity to participate in that webinar, some really good dialogue, numerous participants across biopharma industry and research. And so for your other question, yes, we have continued to reach out to biopharma companies to include the vaccine company. We think that we can provide critical insights here that as we progress through 2021, and prepare ourselves for flu and cold season, and the question that Robin presented is how long does the vaccine work or last; we’ll be able to provide those insights on an individual basis which we believe is meaningful.

As for the rest of your question regarding T-cell and B-cell, we are looking at those as options and to better understand, continuing to research, like many others understanding the virus, the impact on the immune system, and how we respond as individuals. The cPass test is FDA EUA authorized and so was a great option for us to partner with GenScript to bring that forward quickly. As the pandemic evolves and as the discussions evolve, we will evaluate if it makes sense to add others as well.

Great. And then just lastly for me, I was wondering if you might be able to break out, great to see recovery in the base business. But I was wondering if we might get some insight into the oncology channels versus the pulmonologist, VeriStrat, and GeneStrat drivers versus the Nodify product lines, if you're seeing growth across the board, or if it’s mostly on the Nodify side? Thank you.

Thanks, Sung Ji. Good question. We see it being very consistent and similar. Obviously, we've highlighted that pulmonologists were significantly impacted as they were pulled into ICUs and ERs early in the pandemic. And then whenever there was a spike or resurgence, they continued to be pulled back in. When they were pulled in, though the one thing that also occurred is potential patients were told to stay home, right, stay in distance yourself. Our experience across the multiple medical specialties that we call on and consult with is we are seeing a similar recovery in return. We're pleased with that. I think for all of us, it's exciting to see that we're making progress. We're coming out of this, and there is some sense of normalcy on the horizon.

Great. Thank you so much.

Thank you, Sung Ji.

Thank you. Actually, no further questions. This concludes the question-and-answer session and today's conference call. Thank you for participating, and you may now disconnect. Everyone have a great day.
