The U.S. FDA continues to modify its emergency use authorization (EUA) policy for testing for the SARS-CoV-2 virus, although workplace testing is still on the agency’s to-do list. The FDA’s Tim Stenzel noted on a May 6 briefing that serological tests for antibodies must now demonstrate an overall sensitivity of 90% and overall specificity of 95%, a set of standards that might challenge some tests that are available under the EUA policy.
