Bio Break: Laboratory Developed Tests vs. In Vitro Diagnostics

Sector: Diagnostics
Topic: Bio Break

In this episode of Bio Break, Joris van der Heijden and Nick Allan dive into the FDA’s new regulations surrounding Laboratory Developed Tests (LDTs) and their impact on the medical device industry. As LDTs grow in complexity, including applications like genetic testing and AI-driven diagnostics, these regulatory changes mark a significant shift for laboratories, developers, and healthcare providers.

Nick, drawing on his experience with medical device development, explains the critical distinctions between LDTs and In Vitro Diagnostics (IVDs). He provides insights into why these changes are happening and what they mean for developers working to bring innovative diagnostic tools to market.

Key takeaways from the episode include:

  • Understanding the Difference: LDTs are clinically validated tests performed in CLIA-approved labs but do not require FDA regulatory clearance, unlike IVDs, which are classified as medical devices.
  • The Shift in Regulation: The FDA is transitioning from selective enforcement to increased scrutiny due to the growing complexity and impact of LDTs, such as cancer diagnostics and genetic testing.
  • Implications for Developers: Nick explores how the new regulations add layers of oversight but also improve the safety, accuracy, and reliability of tests with far-reaching implications for patient care.

Joris and Nick discuss the broader industry impacts, including the challenges and opportunities presented by these regulatory changes. While some pushback is expected, they highlight how these steps are ultimately beneficial for innovation and patient outcomes, ensuring that advanced diagnostics meet higher standards of clinical utility and reliability.

This episode is essential viewing for medical device developers, diagnostic innovators, and healthcare professionals navigating the evolving regulatory landscape. Gain a clear understanding of how the FDA’s increased involvement in LDTs is shaping the future of diagnostics and how to stay ahead in this rapidly changing environment.

Why Barium Sulfate Is a MedTech Powerhouse

Mark and Ariana explore the surprising versatility of barium sulfate—a material used widely in both diagnostic procedures and medical device manufacturing. While many recognize it as the contrast agent you drink before an X-ray, it’s also a key additive that enhances plastic components across the healthcare industry.

Alzheimer’s Blood Test for Early Detection

We explore a groundbreaking shift in how Alzheimer’s disease may soon be diagnosed. Instead of relying on invasive spinal taps or costly PET scans, researchers have developed a blood test that detects key proteins associated with the disease—offering a more accessible and patient-friendly screening method.
