Rapid antigen detection test for SARS-CoV-2 proves more effective than expected, large study reports

In what is believed to be the largest prospective study of its kind to date - involving some 6,000 patients seen at the Baltimore Convention Center Field Hospital (BCCFH) during a 10-day period around the beginning of 2021 - researchers at Johns Hopkins Medicine, the University of Maryland Medical Center, the University of Maryland School of Medicine and four other collaborators report that a rapid antigen detection test for SARS-CoV-2, the virus that causes COVID-19, proved more effective than expected when compared with virus detection rates using the established standard test, the polymerase chain reaction (PCR) assay.
