Regulation of Laboratory-Developed Tests

Area of Science:

• Clinical Laboratory Science
• Regulatory Affairs
• Medical Diagnostics

Background:

• The Verifying Accurate Leading-edge IVCT Development (VALID) Act discussion draft proposes significant regulatory changes for in vitro diagnostics (IVDs).
• This legislation aims to establish a unified regulatory framework for both conventional IVDs and laboratory-developed tests (LDTs) in the United States.
• Current regulatory oversight for IVDs and LDTs differs, presenting challenges for a single, comprehensive system.

Purpose of the Study:

• To offer a clinical laboratory viewpoint on the VALID Act discussion draft.
• To highlight critical considerations for IVD regulatory reform from the perspective of clinical laboratories.
• To ensure the unique aspects of laboratory medicine are understood before legislative changes are enacted.

Main Methods:

• A literature review on the regulation of laboratory-developed tests (LDTs).
• Discussion of key concerns for clinical laboratories regarding proposed IVD regulatory reforms.
• Analysis of the implications of device-centric regulatory models for clinical laboratory practice.

Main Results:

• Fostering innovation, ensuring patient safety, and protecting the practice of laboratory medicine are crucial issues.
• Clinical laboratories face challenges adapting to device-centric regulatory oversight models due to their non-manufacturing nature.
• Minimizing undue regulatory burden is essential for the effective functioning of clinical laboratories.

Conclusions:

• A clinical laboratory perspective on LDTs is vital for informed decision-making on IVD regulatory reform.
• Incorporating this perspective is imperative before advancing future legislative proposals like the VALID Act.
• The unique operational context of clinical laboratories must be considered to avoid unintended negative consequences.
