Benigno, right, 489th Attack Squadron, flight and operational medical technicians demonstrate a serology test at Creech Air Force Base, Nevada, July 7, 2020. The objective is to determine if the serology test better identifies those that had COVID-19 but were asymptomatic or not diagnosed, or if the saliva test is sufficient for evaluation. Research from JBLE suggests that swab tests have a sensitivity of 70-80% and that serology has a 98% sensitivity. (U.S. Air Force photo by Staff Sgt. Omari Bernard)
