This follows a similar lawsuit by ACLA on May 29.
While the FDA's case in May was 450 pages and this is 83, the original FDA filing was only 59 pages of legal complaint, followed by various testimonials and attachmeents. In that sense, the AMP legal case is actually longer. It's filed in the Southern District of Texas; I think the ACLA was filed in the Eastern District.

FDA's Overreach and the Impact on Laboratory Developed Tests: A Critical Analysis
The recent legal case, Association for Molecular Pathology (AMP) et al. v. United States Food and Drug Administration (FDA), presents a pivotal moment for the laboratory industry, particularly in the regulation of Laboratory Developed Tests (LDTs). The plaintiffs, including AMP and Dr. Michael Laposata, challenge what they describe as an unprecedented regulatory overreach by the FDA. This case, now under the jurisdiction of the United States District Court for the Southern District of Texas, could reshape the landscape of diagnostic testing in the United States, with significant implications for laboratories, healthcare providers, and patients.
Background: The Regulatory Landscape
Historically, the regulation of LDTs has been distinct from that of medical devices. LDTs, which are developed and performed within a single laboratory, have been subject to the Clinical Laboratory Improvement Amendments (CLIA) of 1988, overseen by the Centers for Medicare & Medicaid Services (CMS). This framework was designed to ensure the accuracy and reliability of laboratory tests while allowing laboratories the flexibility to develop innovative diagnostic procedures tailored to patient needs.
In contrast, medical devices, which include commercially distributed diagnostic tools, have been regulated by the FDA under the Federal Food, Drug, and Cosmetic Act (FDCA) since 1938, with significant amendments in 1976. These regulations impose strict premarket review and postmarket control requirements, designed primarily for mass-produced devices used widely across the healthcare industry.
The FDA's Final Rule: A Shift in Authority
The FDA’s recent Final Rule marks a significant departure from the established regulatory framework. For the first time, the FDA asserts its authority to regulate LDTs as medical devices, subjecting them to the same stringent premarket review, postmarket controls, and compliance requirements that apply to mass-produced diagnostic devices. This shift is seen by the plaintiffs as a direct challenge to the legislative intent of both the FDCA and CLIA.
According to the complaint, the FDA’s move not only disregards the distinct regulatory structure Congress established but also threatens to impose significant financial and operational burdens on laboratories. The FDA itself estimates that compliance with its new mandates could cost the laboratory industry billions of dollars annually, a figure that many in the industry believe to be a conservative estimate.
Impact on Laboratories and Healthcare
The plaintiffs argue that the FDA's regulation of LDTs will have far-reaching consequences for laboratories, particularly those serving specialized or underserved populations. Smaller laboratories, which often operate with limited resources, may struggle to meet the new regulatory demands, leading to closures, consolidations, or the abandonment of innovative testing procedures. This, in turn, could reduce competition and stifle innovation, ultimately harming patients who rely on timely and accurate diagnostic tests.
Moreover, the FDA's Final Rule is expected to exacerbate the existing shortage of pathologists in the United States by increasing the regulatory burden on laboratories and driving professionals out of the field. This shortage could further reduce access to critical diagnostic services, particularly in rural and underserved areas.
Legal Arguments and the Path Forward
The legal arguments presented by the plaintiffs hinge on the interpretation of the FDCA and CLIA, as well as the Administrative Procedure Act (APA). They contend that the FDA has overstepped its authority by unilaterally expanding its regulatory reach without clear congressional authorization. They also argue that the FDA's Final Rule is arbitrary and capricious, relying on unverified and anecdotal evidence to justify its new regulatory scheme.
The outcome of this case will have significant implications for the laboratory industry. If the court sides with the plaintiffs, it could lead to the invalidation of the FDA's Final Rule, preserving the existing regulatory framework under CLIA. However, if the court upholds the FDA's authority, laboratories across the country will need to navigate a complex and costly regulatory environment, with potentially profound effects on the availability and quality of diagnostic testing.
Conclusion
The AMP et al. v. FDA case is more than a legal battle; it represents a critical juncture for the future of diagnostic testing in the United States. As the laboratory industry waits for the court's decision, the stakes are clear: the outcome will either reinforce the regulatory status quo or usher in a new era of FDA oversight that could reshape the industry for years to come.
This case serves as a reminder of the delicate balance between innovation and regulation in the healthcare sector. As laboratories continue to push the boundaries of diagnostic science, the need for a regulatory framework that supports both innovation and patient safety has never been more apparent.
Compare the ACLA case and the newer AMP case. Thanks!
The May lawsuit filed by the American Clinical Laboratory Association (ACLA) and the August lawsuit from the Association for Molecular Pathology (AMP) share similarities in their fundamental opposition to the FDA's regulatory approach toward Laboratory Developed Tests (LDTs). However, they differ in their legal strategies, the scope of their arguments, and the specific relief they seek. Here's a comparative analysis:
Similarities Between the ACLA and AMP Lawsuits
Challenging FDA's Authority: Both lawsuits fundamentally challenge the FDA's authority to regulate LDTs as medical devices under the Federal Food, Drug, and Cosmetic Act (FDCA). They argue that LDTs are services, not products, and therefore fall outside the scope of the FDA’s regulatory jurisdiction.
Reliance on CLIA: Both cases emphasize that LDTs are already regulated under the Clinical Laboratory Improvement Amendments (CLIA) of 1988, which they argue is the appropriate regulatory framework for these tests. They assert that CLIA, overseen by the Centers for Medicare & Medicaid Services (CMS), provides sufficient oversight to ensure the safety and efficacy of LDTs.
Legal Grounds: Both lawsuits cite violations of the Administrative Procedure Act (APA), arguing that the FDA’s Final Rule exceeds the agency’s statutory authority and is arbitrary, capricious, and contrary to law.
Concerns About Innovation and Access: Both the ACLA and AMP highlight the potential negative impact of the FDA’s rule on innovation and patient access to critical diagnostic tests. They argue that subjecting LDTs to the FDA’s medical device regulations would impose significant financial and operational burdens on laboratories, stifling innovation and reducing the availability of important tests, particularly for rare diseases or specialized patient populations.
Key Differences Between the ACLA and AMP Lawsuits
Scope of Plaintiffs:
- ACLA: The ACLA lawsuit represents the broader laboratory industry, including large national clinical laboratories and organizations like HealthTrackRX, which is involved in infectious disease diagnostics. The lawsuit emphasizes the role of these laboratories in providing a wide range of diagnostic tests to clinicians and patients across the country.
- AMP: The AMP lawsuit, while also representing the interests of clinical laboratories, is more focused on the specific concerns of molecular pathologists and the impact of the FDA’s rule on molecular diagnostic testing. AMP’s legal arguments are closely tied to the specialized nature of molecular pathology and the unique challenges that the FDA’s rule poses to this subset of the laboratory industry.
Legal and Regulatory Arguments:
- ACLA: The ACLA lawsuit places significant emphasis on the long-standing regulatory framework under CLIA and argues that the FDA's Final Rule overreaches by attempting to regulate professional laboratory services as medical devices. It also highlights Congress's repeated refusal to grant the FDA the authority to regulate LDTs as devices, as evidenced by the failure of the VALID Act to pass.
- AMP: The AMP lawsuit builds on these arguments but also delves deeper into the specifics of molecular diagnostics. It argues that the FDA's attempt to regulate LDTs ignores the complex and specialized nature of these tests, which are often tailored to individual patients and require a high degree of professional judgment and expertise. AMP also emphasizes that the FDA’s rule could disrupt the practice of precision medicine, which relies heavily on molecular diagnostics.
Requests for Relief:
- ACLA: The ACLA lawsuit seeks declaratory and injunctive relief to vacate the FDA’s Final Rule and prevent its enforcement. It argues that the rule is unlawful and would cause irreparable harm to the laboratory industry.
- AMP: While the AMP lawsuit also seeks to overturn the FDA’s rule, it goes further in requesting that the court recognize the unique nature of molecular diagnostics and explicitly limit the FDA’s regulatory authority in this area. AMP’s lawsuit includes detailed arguments about the potential impact on molecular pathology practice, making a case for why these tests should be exempt from the FDA’s regulatory reach.
Focus on Specific Types of Tests:
- ACLA: The ACLA lawsuit broadly addresses all LDTs, covering a wide range of diagnostic services provided by laboratories across the country.
- AMP: The AMP lawsuit specifically focuses on molecular diagnostics and the specialized nature of these tests. It argues that the FDA’s rule would disproportionately harm this area of laboratory medicine, which is critical for personalized medicine and the treatment of complex diseases like cancer.
What's in the AMP Lawsuit but Not in the ACLA Lawsuit?
Emphasis on Molecular Pathology: The AMP lawsuit goes into greater detail about the implications of the FDA’s rule for molecular pathologists and the practice of precision medicine. It highlights the unique challenges that molecular diagnostics face under the FDA’s regulatory framework, which is designed for mass-produced medical devices rather than highly specialized laboratory services.
Impact on Precision Medicine: The AMP lawsuit specifically addresses the potential disruption to precision medicine, arguing that the FDA’s rule could undermine efforts to provide personalized care to patients with complex conditions. This argument is less pronounced in the ACLA lawsuit, which focuses more broadly on the impact of the rule on the laboratory industry as a whole.
Detailed Critique of FDA’s Interpretation: The AMP lawsuit provides a more detailed critique of the FDA’s interpretation of the FDCA as it applies to LDTs, arguing that the agency has failed to consider the distinct nature of molecular diagnostics and the professional services provided by laboratory pathologists.
In summary, while both lawsuits share common ground in opposing the FDA’s regulatory approach to LDTs, the AMP lawsuit offers a more focused and detailed argument related to molecular diagnostics and the practice of precision medicine. The ACLA lawsuit, on the other hand, provides a broader industry perspective and emphasizes the role of CLIA in regulating laboratory services. Both lawsuits are crucial in shaping the future of LDT regulation, but they approach the issue from different angles and with varying emphases.
