The U.S. FDA’s stated policy is that it will not review emergency use authorizations (EUAs) for lab-developed tests (LDTs) for the COVID-19 pandemic, but that doesn’t mean labs are completely shut out. The FDA’s Toby Lowe said that a lab that wants to pair an assay that already has an EUA with a new software installation on lab instrumentation can work with the assay developer to update that EUA.
