Frequent testing improves the detection of SARS-CoV-2 Detecting SARS-CoV-2, the virus that causes COVID-19, improves with regularity of testing, whether using rapid antigen tests or PCR molecular tests. The PCR test is considered the gold standard for diagnosing COVID-19 infection, but cost and infrastructure issues, as well as wait times for PCR results, have limited its use more broadly as a screening tool for asymptomatic people because rapid results are needed to interrupt the chain of transmission. In a highly anticipated study that compares rapid antigen and laboratory PCR approaches for COVID-19 serial screening, researchers affiliated with the National Institutes of Health s Rapid Acceleration of Diagnostics (RADx) initiative reported results from 43 people infected with the virus. They found that both testing methods were equally effective in detecting SARS-CoV-2 infection when tests were given on a regular cadence every three days.
