Each test site consists of two trailers. The first trailer serves as an intake structure. Patients enter in groups of four and soldiers help them complete the necessary paperwork from behind a protective booth. Once intake forms are completed, each patient is given a packaged test kit and directed to the second trailer with their kit in hand. Upon entering the second trailer, patients sit on a bench two at a time and give their test kits to waiting doctors, who are separated from patients by a layer of protective plastic. The doctors administer the test from behind the protective booth using armhole gloves. After the test has been administered, patients take their securely packaged test kits and drop them into a receiving box for analysis.
