2021 CORPORATE RESPONSIBILITY REPORT I 22 As part of these efforts, Quest Diagnostics partnered with Carnival Corporation and Royal Caribbean, the 2 largest cruise lines in the US, to make pre-board COVID-19 testing more accessible and convenient for guests, offering the reassurance of a trusted national laboratory provider. Regardless of COVID-19 vaccination status, all cruise passengers must present negative COVID-19 test results 2-3 days before embarking. In establishing their program, Carnival, Royal Caribbean, and Quest understood the importance of testing passengers before they arrived at their ports—thereby avoiding port congestion and the costs and frustration that could result from receiving positive COVID-19 tests at port, preventing guests from being allowed to board. Instead, the Carnival, Royal Caribbean, and Quest testing programs help to streamline pre-cruise preparation. By offering passengers the convenience of receiving quality COVID-19 testing close to home, the program makes testing available at more than 2,200 Quest Diagnostics patient service centers and select Walmart locations, Giant Eagle drive-throughs, and other retail pharmacy testing locations throughout the US. A return to “Tennis Paradise” Referred to as “Tennis Paradise” by the tennis community, the BNP Paribas Tennis Open is a professional men’s and women’s tennis tournament in Indian Wells, CA traditionally held in March. Due to the COVID-19 pandemic, the organizers canceled the 2020 tournament and rescheduled for October 6 to 17, 2021, turning to Quest for assistance. Returning safely to the courts and courtside required a multifaceted effort. Quest employees registered all tournament participants and attendees and collected PCR and antigen samples (resulting in >4,500 samples) from all in attendance, including world-class players, coaches, family members, international media, tournament officials, and even VIP world champion tennis legend Billie Jean King. Quest employees tested Quest’s initiatives for returning to the “business of play” (continued) antigen samples directly on-site and provided results in fewer than 20 minutes. They also sent PCR samples out daily to Quest’s lab in San Juan Capistrano, CA. This was the third world-class tennis event in 2021 for which Quest served as the testing lab for the Association of Tennis Professionals (ATP) and the Women’s Tennis Association (WTA) — as part of its ongoing commitment to form innovative partnerships to enhance health, safety, and well- being in all walks of life. Our continued safe return to all we love As we learn to live with the ongoing challenges of COVID-19 and its endemic presence, Quest will continue to develop innovative partnerships to help us all return safely to the recreational activities that form such an important part of our lives.
