Thanks, Nancy. I would first like to provide a quick overview of our core diagnostics business, followed by an update on our progress with InteliSwab. For the first quarter, the overall Diagnostics business unit revenue was $38.3 million and grew 163% versus last year. While most of this growth was driven by the addition of InteliSwab, our global diagnostics business excluding InteliSwab grew 11% versus the prior year. This represents strong growth, especially in light of the Q1 headwinds from our HIV OTC sales to the CDC Let's Stop HIV Together Program and the lapping of the Bill and Melinda Gates subsidy, which was in effect for most -- much of our international HIV business in Q1 of last year. Our core domestic diagnostic business, excluding InteliSwab grew 7% in the quarter due primarily to increased employee drug testing as more people returned to work and gains in our grant revenues from the US government versus Q1 of last year. Our domestic HIV revenue declined year-over-year due solely to the lapping of last year's Q1 CDC Let's Stop HIV Together Program, where our OraQuick In-Home HIV test kits were shipped directly to consumers. In that regard, we are pleased to announce that the CDC recently issued a $33 million grant opportunity notification specifically for the mass mailing of HIV self-test to persons disproportionately affected by HIV in the US. This has an estimated award and start date of September 30th, 2022. Given that OraSure is the only FDA-approved OTC HIV self-test in the United States, we would expect to benefit from this award via the partner's bidding on its execution. We believe this represents a continuation of the successful pilot program from Q1 last year and could lead to several quarters of strong HIV sales in late 2022 and early 2023. We also believe along with the recent COVID-19 testing initiative, this program demonstrate a new potential model for the US government to take a more direct testing role in public health for major diseases by targeting the highest need communities. Outreach testing such as this is an area where OraSure's easy to use tests have a substantial benefit versus other tests. And we believe outreach or direct-to-consumer testing program can also provide strong health economics given the low cost of testing and sizable cost savings of disease prevention. We see this as an area of future opportunity for the diagnostics business for our existing products, as well as other disease and wellness testing opportunities, which could utilize the same model. Outside the US, the international diagnostic business grew 20% versus the prior year quarter and grew even faster on a volume basis given the expiration of the Bill and Melinda Gates subsidy in June of 2021. Excluding the impact of this subsidy, international Diagnostics grew 34% versus prior year. Our strong international growth in the first quarter is partially reflective of our strategy to expand the reach of our product into new international market. As a reminder, in the second half of 2021, we received our Thailand pre-sale certification, which will allow us to register the product in Asian and Latin American countries, regions we were unable to access without this certification from the country of origin. In addition, early in the first quarter of this year, we launched our HIV self-test into six European countries, including the UK, Germany, France, Spain and Portugal, where the test will be available in retail pharmacies. While these initiatives take time to garner traction, we believe they will help contribute to our international growth and importantly increase access for HIV self-testing around the world with our proprietary oral fluid HIV self-test. Now I would like to discuss InteliSwab and our operational progress in the quarter, which was significant. As a reminder, Diagnostics operations was integrated into the business unit under my leadership at the start of this year. As previously announced, we hired an operations consulting firm used by the National Institute of Health RADx program with deep expertise in manufacturing scale of rapid antigen test. This team made significant progress during the quarter, identifying major bottlenecks and areas for efficiency improvements. In Q1, we have resolved all prior scale-up issues for InteliSwab, increased production greater than fourfold between early January and April and reduced scrap from approximately 30% to less than 1% in the quarter. These significant improvements were due to a methodical Lean Six Sigma approach, which entails several key steps. First, we uncovered that the manual handling of our assay strip contained inside the test stick was causing our scale-up challenges. We have since changed procedures and automated our assay card production completely. Second, we mapped and measure the process to determine the rate-limiting step and change settings on our robotic assembly to improve the part per minute output. We then turn to the next limiting step where we optimize setting and vision systems on our automated striping and assay car assembly machines. These changes improved output, while also reducing in-process scrap. We continue to find more opportunities for improvement as we further optimize the manufacturing process. In early government procurement contract and the commercial market, there was significant work that went into these changes and I am exceptionally proud of our team and the NIH RADx team in driving these meaningful improvements. Beyond capacity, we also focused on efficiency and many of the changes listed above reduced our scrap rates and material waste as well. To give you a sense for how significant these changes were in the quarter, our finished goods scrap rates declined from approximately 30% in early January to less than 1% by late March. While we have made significant progress, we continue to believe that there is room for continued improvements in our processes. We have created a detailed cost of goods sold improvement plan, which outlines key areas for profitability improvement, including our packaging redesign, efficiencies through global logistics and shipping, efficiencies associated with further process automation and efficiencies garnered through site optimization and workflow design. In aggregate, we believe we can dramatically reduce our operations cost structure in the coming years and our longer-term vision is to have a highly automated, continuous manufacturing process, utilizing the advantages of our Department of Defense capital equipment contract that will benefit all of our lateral flow products. We view improving our cost structure as strategically important, given gross margin improvement can unlock further investment in R&D and sales and marketing to drive innovative new products and opportunities in new market segments. This quarter, we continued to provide InteliSwab to the Department of Health and Human Services as part of our formerly announced procurement contract. The US government has told us, they plan to continue to buy InteliSwab ongoing through the year as they support several programs, which have the need for ongoing consistent testing. This helps even out demand and enables continued shipments even in lower periods between surges. We are also working to continue to grow our commercial footprint for InteliSwab. Following the Omicron surge this winter, we have seen a reduction in commercial testing and high inventory levels at both customers and distributors. Consequently, we believe the commercial business will remain somewhat tepid until we see another surge in coronavirus infection or until inventory levels come down. We also continue to garner data to support InteliSwab accuracy in the phase of new variants. As required with our emergency use authorization, OraSure initiated studies using live SARS-CoV-2 Omicron virus at the National Institute of Health, Rocky Mountain Lab to evaluate our test ability to detect this variance and all other variants of concern. Importantly, the data indicates that InteliSwab detects the Omicron variant at similar levels of detection as it did with all other variants of concern and the original Wuhan strain. The NIH studies are now published in virus with the limit of detection of InteliSwab against all variants. In conclusion, we made substantial progress this quarter in our manufacturing scale up, have begun to optimize our process to improve efficiency and are highly focused on a multiyear journey to improve our cost structure and profitability. We are excited by the opportunities in front of us and strongly believe that the role for easy-to-use test in point of care and home settings is growing as our health care system evolves to continue to empower patients. With that, I am pleased to turn the call over to Cathy to discuss our Molecular Solutions business unit.
