Serial rapid antigen testing on par with PCR COVID-19 tests, RADx team reports By Susan E.W. Spencer July 07, 2021 A longitudinal study co-authored by UMass Medical School researchers as part of the National Institutes of Health’s Rapid Acceleration of Diagnostics (RADx) initiative reported that PCR testing for SARS-CoV-2 and rapid antigen testing were equally effective in detecting infection when tests were given at least twice per week. Study results represent good news for widespread prevention programs because antigen tests at the point of care or at home can deliver immediate results and are less costly than lab tests. While individual PCR tests, considered the gold standard, are more sensitive than antigen tests particularly early in infection, the results showed that both testing approaches can give 98 percent sensitivity when taken regularly as part of a screening program, according to a news release from NIH. That’s good news fo
