Prepared Remarks:

Operator

Good afternoon, everyone, and welcome to the OraSure Technologies' First Quarter 2021 Financial Results Conference Call and Simultaneous Webcast. [Operator Instructions]

I would now like to turn the call over to Jeanne Mell, Vice President of Corporate Communications for OraSure. Jeanne?

Jeanne Mell -- Vice President, Corporate Communications

Thank you, operator. With us today are Dr. Stephen Tang, President and Chief Executive Officer; and Mr. Roberto Cuca, Chief Financial Officer. Dr. Tang and Mr. Cuca will begin with opening statements, which will be followed by the question-and-answer session.

Before I turn the call over to Dr. Tang, you should know that this call may contain certain forward-looking statements, including statements with respect to revenues, expenses, profitability, earnings or loss per share and other financial performance, product development, performance, shipments and markets, business plans, regulatory filings and approvals, expectations and strategies.

Actual results could be significantly different. Factors that could affect results are discussed more fully in the company's SEC filings, including its registration statement, its annual report on Form 10-K for the year ended December 31, 2020, its quarterly reports on Form 10-Q and its other SEC filings. Although forward-looking statements help to provide complete information about future prospects, listeners should keep in mind that forward-looking statements are based solely on information available to management as of today. The company undertakes no obligation to update any forward-looking statements to reflect events or circumstances after this call.

With that, I will turn the call over to Dr. Stephen Tang.

Stephen S. Tang -- President and Chief Executive Officer

Thank you, Jeanne, and thank you everyone for joining us today. I hope you and your families are safe and well. I am pleased to report another record quarter for OraSure. Our 85% growth in first quarter net revenues represents the third quarter in a row of year-over-year double-digit revenue growth. Our sample collection devices for COVID-19 molecular testing continue to make a significant contribution to our revenues, and our genomics, microbiome, and domestic HIV diagnostic businesses showed strong performance as well. We achieved a significant milestone in March when we submitted our COVID-19 rapid antigen test to the U.S.

Food and Drug Administration for Emergency Use Authorization, and look forward to bringing both a prescription home test and a professional test for point of care use to market. We are confident in the market potential for our COVID-19 products, as well as the resilience of our non-COVID businesses. Total net revenues of $58.6 million for the first quarter were driven by strong revenue performance of $43.2 million from the Molecular Solutions Business Unit. We recorded $27.4 million in revenue from our sample collection kits for COVID-19 molecular testing and expect our molecular sample collection kits to continue to meaningfully contribute to our business as testing remains a key strategy to combat the pandemic.

Top of mind for investors is the outlook for COVID-19 testing given the downward trend in testing numbers. Before providing further detail on our activities, I'd like to offer our perspective on the global COVID-19 testing landscape. Here in the U.S., vaccines are readily available and the number of cases in the U.S. has dropped meaningfully since the start of the year. However, as variants continue to spread, testing will continue to play a crucial part in mitigating the spread of the virus and helping to safely reopen workplaces, schools, and other places where people gather.

A recent McKinsey report notes that rapid, accurate testing will play a key role as the transition back to pre-pandemic routines continues. The emergence of new, more contagious variants of the coronavirus underscores the importance of testing to detect infection even as vaccination campaigns continue. Scientists are particularly concerned about the rising prevalence of variants, which they say could prolong the pandemic. When you factor in vaccine hesitancy, it becomes apparent that achieving herd immunity may take longer than hoped for -- or even be elusive. Experts estimate that 70% to 85% of the population must be vaccinated to stop the spread of COVID-19.

Yet, a quarter of Americans say they probably or definitely will not get vaccinated. In some states supply is now higher than demand. Outside the U.S., however, the vaccine rollout is slower. Bloomberg projects it will take years to achieve significant global herd immunity, while McKinsey notes that herd immunity may look different across the world, with some areas achieving it, others moving in and out of it, and some failing to achieve it due to vaccine hesitancy.

Market research reports forecast a robust testing market with estimates of total global volumes for molecular and antigen tests in the range of two billion to four billion tests in 2021. Consequently, we believe the need for convenient, safe and accurate testing will continue alongside vaccination rollouts, and our tests and molecular sample collection kits will be critical to this effort.

OraSure is dedicated to simplifying COVID-19 testing. Our tests and collection kits are all centered on the convenient, pain-free self-collection of samples, making it easier for people to know if they have COVID-19. This simplicity and ease of use can help increase access to testing, alleviate the burden on the healthcare system, minimize exposure risks, and conserve personal protective equipment.

Our molecular sample collection kits made by our DNA Genotek subsidiary continue to drive performance showing continued sequential quarterly growth. Demand has been driven by both high-volume repeat orders from existing customers and from new customers engaged in back-to-work and back-to-school testing programs around the world. As a reminder, our OMNIgene ORAL and ORAcollect RNA collection devices have received EUAs from the FDA allowing for the unsupervised use of these devices at home or in healthcare settings when used as part of an approved or validated at-home test kit. They are also included in eight EUAs received by DNA Genotek's customers.

ORAcollect RNA saliva collection devices have been used in more than two million COVID-19 tests developed by DNA Genotek customer Quadrant Biosciences in partnership with SUNY Upstate Medical University, up from the one million administered tests SUNY announced in February of 2021. This test has been used extensively by State University of New York campuses since the start of the fall 2020 semester.

Turning to our COVID-19 rapid antigen test, we were delighted to announce in March that we had submitted an EUA application to the FDA for our COVID-19 rapid antigen test for both Prescription Home Use and Professional Use at point of care settings. The concurrent submission for both products represented an acceleration of the Prescription Home Test use product and reflects our continued focus on the home testing market. This easy and intuitive 'swab, swirl and see' test detects active COVID-19 infection with no instrumentation, batteries or smartphone needed to read the results.

Users simply swab their lower nostrils, swirl the swab in buffer solution and see the result right on the test stick a short time later. It's that simple. With just a few steps to follow, we believe our test would be one of the simplest COVID-19 tests on the market. We expect that its simplicity will give users peace of mind that they performed the test correctly and can be confident in the result. Our rapid antigen tests are well suited for use by individuals at home, as well as healthcare providers, employers, pharmacies and universities.

Because they do not rely on batteries, electricity, cell service or WiFi, our tests could be administered wherever testing is needed, such as in underserved communities where vaccinations are low and COVID incidence is high. We have begun manufacturing our antigen test as we await Emergency Use Authorization. We also plan to pursue an over-the-counter indication for our rapid antigen test. Given our experience selling our HIV test over-the-counter for close to 10 years, we are well suited to capitalize on this opportunity once authorized by the FDA.

Turning to our oral fluid antibody test, we have collected the data requested by the FDA and plan to submit separate EUA applications for the ELISA microplate assay and the OraSure Oral Antibody Collection Device. This lab-based antibody test can aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating prior infection. Our test has the potential to be the first oral fluid antibody test to receive FDA Emergency Use Authorization. To date, all of the FDA authorized antibody tests require a venous blood draw or finger stick.

Antibody tests can play a role in community surveillance efforts and seroprevalence studies. We continue to sell this pioneering product for research use only and it has been validated by numerous laboratories. With this qualitative test, individuals would self-collect an oral fluid sample using the OraSure Oral Antibody Collection Device, under the observation of a healthcare professional. The sample would be placed into a buffer vial for storage and transport, and later dispensed onto the OraSure Sars-CoV-2 ELISA microplate for testing in a laboratory.

Each of OraSure's accurate, easy-to-administer testing and collection methods, in conjunction with vaccination efforts, can play a key role in identifying COVID-19 cases, isolating the infected, controlling outbreaks and helping the world get back to normal. We are confident in the sustained market potential for our COVID-19 solutions. As the recent surges around the world have shown, COVID-19 is still having a significant impact worldwide.

We are prepared to address this global opportunity, a molecular sample collection kits are already authorized in Europe and in Canada. We are actively working on the requirements for international regulatory approvals for our rapid antigen test and plan to leverage our existing infrastructure of teams and distributors. If we capture just a small percentage of the global COVID-19 testing market, it will have a meaningful impact on the company.

And with that, I'll turn it over to Roberto for a report on our financials and an update on our COVID-19 manufacturing capacity expansion. Roberto?

Roberto Cuca -- Chief Financial Officer

Thank you, Steve. Our first quarter net revenues increased 85% to $58.6 million from the $31.6 million we reported in the first quarter of 2020, primarily as a result of strong sales of molecular sample collection kits for COVID-19 testing, higher genomics product sales, and increased sales of our over the counter OraQuick In-Home HIV test. This was partially offset by lower sales of our HIV and HCV professional products and risk assessment products. Net product and services revenues were $56.6 million, an 83% increase from the first quarter of 2020.

Total product and service revenues for the company's molecular business unit were $44 million during the first quarter of 2021, an increase of 219% from the first quarter of 2020. This increase included $27.4 million in sales of oral fluid sample collection devices for COVID-19 molecular testing.

Domestic sales of the company's OraQuick HIV tests increased 26% compared to the first quarter of the prior year largely due to higher sales of the over-the-counter OraQuick In-Home HIV test. International HIV and HCV revenues declined 42% over the prior year, due to several large distributor orders, which occurred in the first quarter of 2020 and variations in timing as compared to 2021 ordering. Overall, the underlying international growth in HIV and HCV testing is still strong versus prior year outside of the single-quarter timing impact of these distributor orders.

Gross profit percentage was 65% for the three months ended March 31, 2021 compared to 51% in the same period of 2020 due to an improved product mix of higher gross profit percentage product sales. Net income for the first quarter of 2021 was $3.8 million, or $0.05 per share on a fully diluted basis, compared to a net loss of $7.3 million, or $0.12 per share on a fully diluted basis, for the first quarter of 2020.

First quarter 2021 results included a benefit of $806,000 for the change in the estimated fair value of our acquisition-related contingent consideration compared to a charge recorded in the first quarter of 2020 of $1.1 million. 2021 results also reflect the additional product development and sales and marketing costs incurred for our COVID-19 tests as well as increased tax expense associated with the improved results of the company.

Cash and investments totaled $240.5 million at March 31, 2021. As we disclosed in our press release, we expect revenues of $55 million to $60 million in the second quarter of 2021. We are not providing full year guidance at this time, but we will revisit that option as we get greater clarity on the regulatory status of our COVID-19 antigen and antibody tests.

I'll now turn to our manufacturing capacity expansion efforts for our COVID-19 products, starting with our rapid antigen test. As of the end of the first quarter, all the equipment needed to achieve the previously communicated planned capacity of 55 million units annually is on-site and either installed or in the process of being installed. More specifically, lines capable of manufacturing 44 million units a year are in place with the remainder to be finished by the end of May.

Plans are on-track to achieve 70 million units annually of installed capacity in the third quarter and 120 million units by the second quarter of 2022 as previously disclosed. These are annualized numbers of installed capacity and include our existing tests for HIV, HCV and Ebola, and will require some ramp up time for validation and new employee training.

For our oral fluid antibody test, we currently have installed capacity of 10 million units per year, including existing products, as we have previously communicated. We remain on track to expand this capacity to 20 million units a year by the end of 2021.

Capacity expansion for our molecular sample collection kits exceeds our original projections. We are expanding installed capacity of our molecular sample collection devices to a rate of approximately 80 million units annually in the second quarter of 2021, ahead of the 75 million annual units previously communicated, and further to 105 million units annually by the end of 2021. Of this capacity we expect that seven million to eight million units annually will go to non-COVID-19 applications.

With that, I will turn the call back over to Steve.

Stephen S. Tang -- President and Chief Executive Officer

Thank you, Roberto. I'd now like to provide some brief updates on our non-COVID-19 businesses, which have shown not only resiliency, but in some cases, indications of a return to pre-pandemic levels. In fact, our molecular non-COVID-19 business rebounded beyond first quarter 2020's pre-COVID levels, signaling that COVID-19 headwinds in the molecular market may be subsiding.

Non-COVID molecular product revenue in the first quarter grew 32% over the prior year. Our total genomics business was up 32% for the quarter, with signals of recovery driven by momentum in the Disease Risk Management, Ancestry and Companion Animal markets. Our academic markets for genomics is also showing signs of resilience with 9% growth over prior year quarter.

Our microbiome collection kits business rebounded in the first quarter with a 32% growth over the same quarter a year ago, driven by demand from our commercial customers. We expect our commercial microbiome business will continue to recover as investment continues in the microbiome industry, driving growth potential for both Diversigen services and DNA Genotek kits.

Turning to our Diagnostics Business Unit, overall domestic diagnostics revenue was on par with first quarter 2020, despite COVID-19 headwinds. Sales of our over the counter HIV In-Home test grew by triple digits over the prior year as public health HIV testing programs in the U.S. continue to use our over-the-counter product. For example, the Centers for Disease Control and Prevention is distributing our OraQuick In-Home HIV Tests via a partnership with Insignia, Building Healthy Online Communities and Emory University. CDC's Let's Stop HIV Together campaign is leading the marketing efforts and sending consumers to a unique website link to order tests.

This large-scale and targeted distribution of self-test kits to populations disproportionately impacted by HIV/AIDS will assist CDC in future efforts related to in-home testing strategies and contribute to the Ending the HIV Epidemic initiative. International diagnostics revenue was down from the year prior largely due to unusually large orders from initial program stocking in first quarter 2020 and variable timing associated with restocking. The underlying growth in Q1, outside of these stocking orders, is still strong and we expect international diagnostics revenue in the first half of 2021 to show strong growth versus 2020.

Finally, before we move to the Q&A session, I'd like to share with you a few summarizing thoughts. Our business is strong and we expect our momentum to continue in a balanced manner. As you've seen, our non-COVID revenue is beginning to return to pre-pandemic levels and our COVID-19 related revenue remains robust. We believe the collective contributions from our rapid antigen test and oral fluid antibody test will be substantial subject to receipt of EUAs for these products, and we're confident we'll continue to make significant commercial strides with our molecular sample collection kits.

Lastly, we will leverage our strong balance sheet, with more than $3 per share in cash, to maximize the COVID-19 tailwinds, fund R&D in our non-COVID businesses, and fuel our business development activities. For these reasons, we think we are in an excellent position to capitalize on multiple fronts and drive further growth in the coming quarters.

With that, operator, please open the call up for questions.

Questions and Answers:

Operator

[Operator Instructions] Our first question will come from line of Frank Takkinen from Lake Street Capital. You may begin.

Frank Takkinen -- Lake Street Capital -- Analyst

Hey, thanks for taking my questions. A couple from me today. Starting with the guidance, I was hoping you could help us understand some of the components into the $55 million to $60 million guide looking at the COVID molecular revenues and the growth trajectory they've been on was hoping that you could maybe just tease out directionally that specific line item to give us a better feel for the pieces of guidance in Q2, 2021?

Stephen S. Tang -- President and Chief Executive Officer

Sure. Frank. Thanks for the question. So for the second quarter guidance of $55 million to $60 million we did not include into that any contribution from post-EUA sales of either of our antigen or antibody tests because the authorization timing is uncertain. So that $55 million to $60 million will reflect revenues similar to, or sources similar to what we saw in the first quarter of 2021. We haven't broken it out more granularly by line item or sales contribution. So, I can't give you any additional guidance on the COVID-19 contribution. And any other questions on that?

Frank Takkinen -- Lake Street Capital -- Analyst

No, I'll just ask my follow-up given the international market is becoming more and more important. It seems like, can you just refresh us on the approval process and potential timing to getting your antigen test in the international market?

Roberto Cuca -- Chief Financial Officer

Sure Frank. We are exploring right now the regulatory requirements for our rapid antigen tests outside the U.S. including which are the most attractive markets and the timing of those regulatory processes. So that will come shortly after we receive hopefully favorable word from the FDA on our rapid antigen test and our current submissions. So it will happen as quickly as possible. But of course our first focus is to get into the U.S. market.

But I think you are rightfully focused on the outside U.S. market because that's where the pandemic is still raging in places like India and elsewhere. So, we are very mindful of that. So, of course we have widespread experiences and helping to test for pandemics, including HIV. And I think our experience will serve us well in those markets.

Frank Takkinen -- Lake Street Capital -- Analyst

Perfect. Thanks for the color.

Operator

And our next question will come from the line of Vijay Kumar from Evercore ISI. You may begin.

Vijay Kumar -- Evercore ISI -- Analyst

Hey guys, thanks for taking my question. Stephen maybe on the antigen side, I guess you guys submitted on March 30. So it looks like six weeks approval. We'll put that in at some point in mid May potential approval given that average price $5. What is that I guess that, can you talk about the opportunity for you guys? Can you sell be competitive that those price points and then I had a couple of follow-ups. Yes, let's start with, how you see the opportunity in the U.S.

Stephen S. Tang -- President and Chief Executive Officer

Sure, Vijay. I think as we know the $5 price for that particular product was I think the price to the government, and it was for a professional product since then pricing has been updated, I think, for the developments, particularly in the OTC market. So, we're very conscious of that. I think we're going to have a extremely competitive product regardless of the domain. So that's professional prescription self tests, and even OTC at some point.

And I think that we're looking at the pricing right now on the OTC side in particular, and I think we can be competitive particularly since our product, I think is well-differentiated for its ease of use and simplicity, which I think will become increasingly important as self tests get used more often by a wide range of people. So, I think for us, we remained very confident even though the testing of the -- excuse me, the pricing environment has changed.

Vijay Kumar -- Evercore ISI -- Analyst

Gotcha. So just to be clear Steven the -- I guess when you look at the retail pricing small more think Abbott selling the two-pack test for roughly around $24, $25 you'll be able to match those price levels.

Stephen S. Tang -- President and Chief Executive Officer

I think we will be very competitive in the marketplace considering what the current pricing is and considering the value proposition overall for our product. Yes, absolutely.

Vijay Kumar -- Evercore ISI -- Analyst

Okay. And then two quick follow-ups, one on 2Q, what trends are you seeing in collection kits and some of the molecular testing companies we've seen some pretty good cuts to numbers and on the antigen side how, I guess is this still a meaningful opportunity? Because the question I'm getting at is or short delay and how should we think about antigen contribution in the back half?

Stephen S. Tang -- President and Chief Executive Officer

Sure. Let me just give you some perspective on the overall market. We absolutely have a tremendous opportunity, so we're not too late. The market research form Kalorama Information says that the total global antigen testing market for COVID-19 is about $19 billion a year, $5 billion of that is in the U.S. We have a product, I think that is going to be one of the simplest use on the market that I think will be useful to consumers and to healthcare professionals have confidence in the test results. So, I do think that opportunity is large.

Vijay, as well enough to know that we're a relatively small company compared to the makers of tests that are currently have OTC approval, at least two of them. So, we can do very well for us as a company and for our shareholders even with capturing just a small portion of that antigen test market. And I think we're gearing up our manufacturing capability and looking forward to our product launches accordingly.

On the molecular side Kalorama says that the global molecular testing market is about $17 billion a year. I think the slowdown in lab based testing has been well-documented by you and others. We believe there is going to be an opportunity that's still very strong for us. In the sample collection area, we noted in our prepared remarks that one of our customers Quadrant Biosciences has now surpassed two million tests within the state university of New York system. I think there'll be a need for ongoing tests. Those customers that are well entrenched in testing modalities like SUNY is for their students and their staff will continue to buy. And we are monitoring the situation very carefully.

We've tried to be on the conservative side of our projections for testing overall and we'll continue to do so. So that's why we remain very confident, very optimistic that we can maximize our opportunities for COVID-19 for the rapid antigen tests, for the molecular collection kits and somewhere down the line, even the antibody test. So, I think the prospects for us or remain very strong.

Vijay Kumar -- Evercore ISI -- Analyst

All right. Thanks guys.

Stephen S. Tang -- President and Chief Executive Officer

Thanks, Vijay.

Operator

[Operator Instructions] Our next question will come from the line of Andrew Cooper from Raymond James. You may begin.

Andrew Cooper -- Raymond James -- Analyst

Hey guys, thanks for the questions. Maybe start on the collection side, I guess first, has there been any sort of change in the competitive landscape when you think about pricing or sort of options out there now that we're a little bit past the point where, swabs and twos were such a constraint like they were earlier in the pandemic, just any comment there would be helpful.

And then when we think about big customers like Quadrant or some of the others can you give us a flavor for how much of the sales in 1Q or maybe contracted what the duration might look like or any color there to think about sort of contracts with durability as things progressed through 2021 and beyond?

Stephen S. Tang -- President and Chief Executive Officer

Sure. Andrew we're not seeing switching from our product to other products, first of all. So, I think we've got a very reliable sample collection kit. One of which is a saliva collection kit. The other is a swab, sponge swab kind of configuration, not swab in the nasal swab sense. So, I think that the opportunity is very durable. And so we're not seeing a substitution effect there. The buying behavior of customers I think is remained strong.

I think that they are looking at variability in and their needs and demand as well. I think that's a macro issue with all lab based testing. But the story does hold together for us. Very well, I think because of our close customer relationships and our expanding relationships elsewhere including outside the U.S.

Andrew Cooper -- Raymond James -- Analyst

Okay. That's helpful. And then, maybe just on the antigen side, when you think about OTC, I think the FDA has really sort of lowered the bar for folks there's, as things are progressing. We think about the serial testing and what they're requiring very symptomatic positives and things of that nature. So, what do you need to do to get that particular claim that the OTC claim to the FDA? What's left on the docket for you to get that package together and make that submission?

Stephen S. Tang -- President and Chief Executive Officer

Well, Andrew, I think that's an important question because much has changed in the OTC COVID-19 rapid antigen testing world. Since we spoke in our last earnings call in March, two new products that come on the marketplace, and I think your observation that FDA's requirements have shifted overtime is true. I think that we're fortunate to had a close relationship with FDA dating back to 2012 when we launched our OraQuick In-Home HIV test.

So, we're a known entity to them, particularly for self tests for infectious disease. That's going to help us quite a bit. I think we have a clearer sense today than ever before what we need to do to get a submission for OTC. And so I think we are determined to do so. We're not projecting when, but I think that we're very confident we have the pathway well in hand and well understood.

So, there are a number of things you have to do above and beyond the submissions for the prescription self tests and for the professional tests, which are already under way. But we have been encouraged by a close working relationship with FDA and hope to get that OTC product into submission and on the market as soon as possible.

Andrew Cooper -- Raymond James -- Analyst

And just as a quick follow-up to that, should we expect that it is an authorization for a stand-alone use or for serial, what's the kind of current thinking on the strategy from that perspective?

Stephen S. Tang -- President and Chief Executive Officer

Yes. So one of the things that FDA has made clearer in the past couple months is a difference between a diagnostic test and a screening test. So diagnostic test is one for those who are infectious and a screening test is a test for asymptomatic and others. And screening tests lend themselves to serial testing, which is what you're calling attention to packages that have more than one test in them. We are very well aware of that. I think that can be a good use case for us and we're working toward getting that use case firmed up and getting it through FDA.

Andrew Cooper -- Raymond James -- Analyst

Great. I'll stop there. Thanks.

Stephen S. Tang -- President and Chief Executive Officer

Thank you, Andrew.

Operator

And our next question comes from the line of Brandon Couillard from Jefferies. You may begin.

Matt -- Jefferies -- Analyst

Hey guys, this is Matt [Phonetic] on for Brandon. Thanks for taking the questions. To start, you guys indicated you've started to manufacture your rapid antigen test while you wait you clearance. And clearly a lot is dependent on timing of approval, but any color you can give on how many you expect to have manufactured at launch.

And then I guess what portion of that is already spoken for, or do you expect to be spoken for, at launch across, the number of different potential customers and use cases from back to work to a number of healthcare settings as well? Thanks.

Stephen S. Tang -- President and Chief Executive Officer

Yes, sure Matt. We have not disclosed how much manufacturing we've done at risk, but we are doing so as we speak. And as you noted the approach is to have product ready to go once we have EUA from the FDA. So that is absolutely what we're aiming at. We have different requirements depending on the use of the product. So the professional test, the prescription self test, and somewhere down the road, the OTC will have different labeling and box requirements.

So, we're taking that into account also, but when we get up to full speed in terms of manufacturing and once we have approval we're very confident that we're going to be selling as much product as we can make over time. So, I think we have designs on a steady stream of business over the coming months through 2021 and into 2022. And that's what we're focused on.

Matt -- Jefferies -- Analyst

Great. That's helpful. And then quick one for Robert, gross margin, 65% this quarter, the guidance center calls for similar revenue basis or anything to call it on mix? Or can we kind of expect gross margins to continue to trend and kind of that mid-60s range?

Roberto Cuca -- Chief Financial Officer

So for the first quarter, gross margin was driven very much by mix. So, if you look at the tables at the end of our press release, you'll see that obviously the COVID-19 collection devices kits were up substantially over the prior year. We're -- the sales were mostly nominal, and we've talked about how all of the COVID-19 testing opportunity products are at the higher end of the margin range. On the other side of things, our international sales of our HIV kits were down pretty substantially just due to some timing of shipments.

And so those two things together combined to drive the 65% gross margin percentage. So depending on how exactly those two things shake out proportionally with regard to each other in the second quarter, you could see some change to that gross margin percentage from the first of the second quarter.

Matt -- Jefferies -- Analyst

Super thanks. I'll stop there.

Operator

[Operator Instructions] And I'm not showing any further questions in the queue. Yes, we do have one question from the line of Patrick Donnelly from Citi. You may begin.

Patrick Donnelly -- Citi -- Analyst

Hey guys, thanks for taking my question and squeezing me in. I just wanted to ask on the demand side, obviously you talked a little bit about U.S. versus OUS., and it seems certainly that OUS is a little more compelling long-term, but in the U.S. side, I mean, how much have you guys talked about before approval to the employer side travel? I'm just trying to think of what the demand could look like as you get to the market here. And if there is anything in place in terms of contracts, you may -- if you could just talk through the U.S. piece a bit more, it'd be helpful.

Stephen S. Tang -- President and Chief Executive Officer

Certainly, Patrick. Inbound interest has been strong and remains strong. Particularly in buyer groups, our universities, employers, physician offices, public health and government buying entities. Obviously we cannot promote and contract until we have at EUA. But we've advanced those discussions progressively, as we've been able to share more about the product design and the use cases.

And so we are very confident that those domestic use cases remain intact. I think as testing moves to more self testing options in the marketplace the attributes of our product and their competitiveness versus existing products will be easy to see. So it remains strong, interest remains strong, and we're hoping to confirm all those interests into sales and contracts once we receive our UAS.

Patrick Donnelly -- Citi -- Analyst

Yes. And Steven, maybe on that point, you kind of touched on the competitive side, obviously, the market is getting more competitive as we go here. When you think about the differentiation pieces out there, I mean, how much -- when you think about first mover versus the data itself versus ease of use, how do you rank those things in terms of what you've heard from folks you've chatted with as being the most important when several markets -- several products are on the market. What do you think moves the needle for the potential customer base?

Stephen S. Tang -- President and Chief Executive Officer

Well, I think based on our experience with HIV in-home testing, and we've been on the market, close to 10 years with that product, the ease of use of the product gives people confidence that their results are accurate, and that's the value proposition. So, I can't really speak to how that shapes up with other products on the marketplace. Other than to say, if those are the differentiators, then are our cases very strong.

So, we recognize we're not the first to market, but there are some attributes of our product in terms of ease of use, in terms of the integrated swab into the product design, which I think are going to be extremely helpful to us. And so that's why our outlook remains very strong on the product in the U.S.

Patrick Donnelly -- Citi -- Analyst

Understood. Thank you, guys.

Stephen S. Tang -- President and Chief Executive Officer

Thanks, Patrick.
