Thank you, operator. Good afternoon, everyone, and thank you for joining today's call. With me today is our President and Chief Executive Officer, Doug Bryant; our Chief Financial Officer, Randy Stewart; and our Vice President of Finance, Kristin Caltrider. Our second quarter 2021 earnings release is now available on ir.quidel.com, our Investor Relations website. We will also post our prepared remarks on the Presentations tab of our IR website following the conclusion of this call, on August 5th, for a period of 24 hours. Please note that this conference call will include forward-looking statements within the meaning of Federal securities laws. Forward-looking statements, by their nature involve material risks, assumptions and uncertainties. In particular, our expectations and assumptions around the COVID-19 pandemic impact and response on our business, results of operations and financial condition and that of our suppliers, customers and other business partners are highly uncertain, continuously evolving, and unpredictable. Many possible events or factors could affect our future financial results and performance, such that our actual results and performance may differ materially from those in the forward-looking statements. For a discussion of such factors, please review Quidel’s most recent annual report on Form 10-K, including the section titled Risk Factors, registration statements and subsequent quarterly reports on Form 10-Q, as filed with the SEC. Furthermore, this conference call contains time-sensitive information that is accurate only as of the date of the live broadcast, August 5, 2021. Quidel undertakes no obligation to revise or update any statements to reflect events or circumstances after the date of this conference call, except as required by law. Today, Quidel released financial results for the three and six months ended June 30, 2021.
