This week’s FDA news has been dominated by the tumultuous emergency authorization of convalescent plasma on Sunday, but let’s not forget last week’s news: On August 16, the Department of Health and Human Services (HHS) surprised public health experts by publishing a one-paragraph notice on its website rescinding FDA guidance related to laboratory developed tests (LDTs). The notice states that the FDA will not require premarket review of LDTs absent notice-and-comment rulemaking, including for COVID-19 tests. LDTs are tests “designed, manufactured and used within a single laboratory,” such as tests run by large academic medical centers, hospitals like the Mayo Clinic, and testing giants LabCorp and Quest Diagnostics. Former HHS national coordinator for health information technology Farzad Mostashari described this change as “bizarre” and like “[c]losing the barn door 6 months after the horse left the barn, and 3 months after she moved to a different barn!” What’s going on, and how will this change affect COVID-19 testing?
