Thanks Steve. I would first like to provide a quick overview of our core diagnostic business followed by an update on our progress with InteliSwab. First, for the full year 2021, the overall diagnostic business unit revenue was $90 million and grew 38% versus last year. Our global core diagnostic business excluding InteliSwab product revenue grew 3.5% versus prior year. If you exclude the impact of the June 2021 expiry of the Bill and Melinda Gates Foundation subsidy for our international HIV self-test, the core diagnostic business grew 8.6% versus prior year. In the US, core diagnostic grew 13.3% for the full year 2021. This was driven by strong performance across HIV. HCV and our drug testing business with the reopening of clinics, and new employee hiring, as well as CDC orders for HIV OTC test to mail-to-home as part of the CDCs Let's stop HIV together program. Outside the US, the international diagnostic business declined 6.2% versus prior year, but excluding the Gate subsidy impact, the business was up 3.4%. In addition, we experienced logistical disruptions from the pandemic all year, which impacted the timing of shipments including those at year end. Part of our strategy with our diagnostic business is to accelerate growth by expanding globally, and we have made significant strides on that initiative this past year. In late 2021, we received our Thailand Free Sales Certification, which will allow us to register the product in Asia and Latin American countries, regions we were unable to access without the 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 United Kingdom, Germany, France, Spain and Portugal, where the test will be available in retail pharmacies. This year, the World Health Organization also issued the first guidelines on HCV self-testing, the WHO estimates that 58 million people in the world have Hepatitis C, yet less than one quarter know they are infected. That is over 45 million people who have this disease and do not know it. Importantly, Hepatitis C is curable with medication, if detected early. If not detected Hepatitis C can result in significant liver damage and possibly death. And as stated, quote, the WHO has set a global goal to eliminate HCV as a public health problem by 2030. Meeting this goal requires innovative approaches and service delivery models for reaching the people who remain unaware of their HCV infection and linking them to treatment and care services. Self-testing is one such approach, unquote. These guidelines represent strong support for the continued need for ease of use self-testing by lay users an area where OraSure has a strong product and many years of expertise. In addition, the US also issued its first viral hepatitis elimination plan also focused on eliminating this disease by 2030. The expansion of self-test is core to our strategy to drive both revenue and gross margin growth moving forward. Now, I would like to discuss InteliSwab and the important tailwinds, which now support further COVID-19 self-testing in the United States in particular. As we previously announced in January, while we experienced lower than expected InteliSwab sales per quarter due solely to our supply, we are optimistic about the future trajectory. In January, the Biden administration announced a federal government commitment to purchase a total of 1 billion COVID-19 Rapid antigen tests, distribute them free directly to individuals that request them online, OraSure with our existing US government procurement contract will be able to supply this program in addition to other federal programs as dictated by HHS. In addition to this 1 billion test procurement program, in January, the Biden administration also mandated that commercial insurers as well as Medicare and Medicaid, provide reimbursement for OTC COVID-19 rapid test. Under this program, consumers can now purchase up to eight COVID-19 Rapid home tests per month per person and receive reimbursement from their insurance provider with no associated co pays or deductibles. For those insurers who established preferred retail partners, consumers will be able to obtain tests free of charge by showing their insurance card right in store. The payers will then reimburse retailers at $12 per test, or $24 per two pack. If an insurer does not establish preferred retail partners, then the consumer will need to pay out of pocket and send receipts to their insurer to receive reimbursement. This reimbursement will be at the retail price paid. Given the almost 300 million individuals in this country with health insurance. We believe this expands the theoretical market opportunity for COVID-19 testing in the US to over $150 billion. Furthermore, we would highlight the potential benefits this may have as we look to the future for self-testing, as these types of payer models could be used to empower patients and reduce healthcare costs with other disease states. As a reminder, the market model we shared with investors last quarter, based on epidemiology have less than a 0.5 billion tests assumed as the US market size in fiscal year 2022. Now with these new developments in procurement and reimbursement for OTC rapid tests, we believe the 2022 COVID-19 rapid test market in the United States will be significantly larger than we anticipated. Overall, these changes also make us more optimistic on the long-term durability of the COVID-19 market in the United States, as we plan to scale our production capacity to over 200 million tests per year. We also continue to garner data to support InteliSwab accuracy and to expand indications. At the start of 2022, we added a number of important label expansions for the test. First, in early January, the FDA announced concern that certain lateral flow tests may not be as accurate with the Omicron variant, as required with our emergency use authorization, OraSure initiated studies using live SARS-CoV-2 Omicron virus in an independent third party laboratory to evaluate our testability to detect variants of concern. Importantly, the data indicates that InteliSwab detects Omicron at the same level of detection, as it did with all other variants of concern, and the original Wuhan string. Second, we also recently announced that our InteliSwab tests have been authorized by the US FDA for use in children ages 2 to 14. Prior to this announcement, InteliSwab was authorized for self-testing use in adults 18 and older and in children 15 to 17 when administered by an adult. This is an important indication expansion which enables us to provide tests with numerous test to stay programs being rolled out in many school districts, as well as many other state testing programs focused on household testing. Finally, the company recently announced the launch of a new reporting app InteliSwab Connect, which will allow people to save images of their own results. To easily report their test results to public health authorities and to also provide results to employers. The app will be available on the Apple App Store and via Google Play. In 2022, the US market provides significant demand via both our US government procurement contracts also numerous non-government customers, we will be able to sell all that we can produce. That said we are working to create certain packaging configurations specifically for markets outside the US. And we'll be conducting the necessary studies this year to enable international sales in 2023. In addition, we have plans to improve gross margin for InteliSwab with these configuration changes, and other savings as we scale. Lastly, I would like to discuss our manufacturing scale up with InteliSwab. As part of our organizational restructuring, I assume leadership of the diagnostics operations team at the start of the year. From a background perspective, I'm a chemical engineer with extensive medical device operations management experience. I started my career in engineering and plant management in large chemical plant operation. And in my most recent role prior to OraSure, I lead the Becton Dickinson global Vacutainer business as well as BDS global syringe needle and IV catheter businesses. Collectively, these business manufacture 10s of billions of medical devices in numerous production facilities around the world and represented billions of dollars in annual revenue. To further aid in our operational scale up and in addition to other ongoing efforts, I hired an operations consulting firm used by the National Institute of Health RADx program, with deep expertise in manufacturing scale up in rapid antigen testing. We've been working on process mapping and identifying major bottlenecks where resolution can lead to the greatest incremental efficiency. We also have experts at our contract assembly sites to help identify areas of opportunity for further efficiency. The team has already identified a number of significant areas for improvement to accelerate our scale up and improve our operational efficiency throughout 2022 and beyond, and I am confident in their leadership and ability to assist in our scale throughout 2022. Some of the operational improvements the team has recommended will take time to implement and are exacerbated by the challenges we face in terms of the challenging labor market and global logistical and supply shortages as a result of COVID-19. While we are not providing former InteliSwab guidance or capacity expectations given our strategic alternative process, we do expect to scale InteliSwab modestly in the first quarter with more meaningful gains throughout the remainder of fiscal year 2022. With that, I am pleased to turn the call over to Kathy to discuss our molecular solutions business unit.
