Yesterday, the US Department Health and Human Services rescinded guidance that mandated that COVID-19 tests gain approval from the Food and Drug Administration (FDA) before use, under an executive order from President Donald Trump."As part of HHS's ongoing department-wide review of regulatory flexibilities enacted since the start of COVID-19, the department has determined that the Food and Drug Administration ("FDA") will not require premarket review of laboratory developed tests ("LDT") absent notice-and-comment rule making," HHS said in a document posted to its website yesterday.The decision will allow private and commercial laboratories to manufacture and administer tests, including labs controlled by Quest Diagnostics and LabCorp.
