As the song goes, the Food and Drug Administration’s (“FDA’s”) 2024 Final Rule regulating laboratory-developed tests (“LDTs”) as medical devices (“Final Rule”), is not merely dead—it’s really most sincerely dead.

Perhaps not for good, but for the foreseeable future, at least.

The FDA has let the clock run out on the 60-day time period to appeal the March 31, 2025, decision by the U.S. District Court for the Eastern District of Texas concluding that: 1) the FDA overstepped its authority, and 2) the LDT Final Rule of May 6, 2024, was unlawful. As we explained at that time, the Final Rule would have required virtually all clinical laboratories offering their own LDTs to comply with FDA expectations for medical device manufacturers in phases over a four-year period—with the first compliance deadlines set for May 2025.

The March 2025 opinion by Judge Sean D. Jordan vacated the controversial Final Rule a little more than a month before the first implementation deadlines were to take effect, and remanded the issue back to the FDA.

Clinical laboratories still face uncertainty and the difficult decision of whether to start the work needed to comply with the with Phase 1 expectations under FDA’s Laboratory Developed Tests Final Rule (the “LDT Final Rule”), which remain set to go into effect on May 6, 2025. To be sure, the shift in priorities of the new administration has kept the health care industry on its toes for the last few weeks, especially as the leadership and messaging of the Department of Health and Human Services (“HHS”) has started to come into sharper focus. The theme of ‘deregulation’, particularly when it comes to the activities of the Food and Drug Administration (“FDA”), has sparked interest and discussion among stakeholders in the life sciences industry – including clinical laboratories that are weighing how to approach the upcoming May 6 deadline for compliance.

We discussed the details of the LDT Final Rule in a previous Insight, explaining that as of the May 6, 2025 Phase 1 deadline FDA will expect all laboratories that manufacture LDTs to comply with medical device reporting (“MDR”) requirements, correction and removal reporting requirements, and quality system (“QS”) requirements regarding complaint files.

New from the Diagnosing Health Care Podcast: Laboratories in the United States are facing a major regulatory landscape shift.

The U.S. Food and Drug Administration (FDA) has finalized a new rule ending its historical blanket enforcement discretion over laboratory developed tests (LDTs). What does this mean for labs going forward?

On this episode, Epstein Becker Green attorneys James Boiani, Rob Wanerman, and Megan Robertson lay out the new landscape, analyze existing and potential challenges, and identify key developments to watch for as this new regulatory era unfolds.

As of Monday March 4, 2024—just three months after the end of its comment period on December 4, 2023—FDA’s rule on regulation of laboratory developed tests (“LDTs”) as medical devices is under review by the Office of Information and Regulatory Affairs (“OIRA”) within the Office of Management and Budget (“OMB”). While review by OIRA is capped at 90 days by Executive Order 12866, there is no minimum period required, and therefore action can be taken any time between now and June.

During this election year, FDA’s efforts to push the rule forward fairly quickly is ...
