Managing Laboratory Developed Tests (LDTs) in Hospitals: Regulations, Challenges, and Strategies

Written By Lauren Davis, BS, CPT

Summary

  • There are currently over 11,000 Laboratory Developed Tests (LDTs) being used in the United States.
  • The regulation of LDTs is a controversial topic, with some arguing for stricter oversight while others believe in the need for flexibility and innovation.
  • Hospitals must carefully manage their supply and equipment needs to ensure they have access to the necessary LDTs for patient care.

Introduction

Laboratory Developed Tests (LDTs) play a crucial role in healthcare by providing important diagnostic and prognostic information to Healthcare Providers. In the United States, there are over 11,000 different LDTs currently in use, with new tests being developed and implemented regularly.

Regulation of LDTs

The regulation of LDTs has been a topic of debate in recent years. Currently, LDTs are overseen by the Centers for Medicare and Medicaid Services (CMS) under the Clinical Laboratory Improvement Amendments (CLIA) program. Some argue that LDTs should be subject to more stringent Regulations by the Food and Drug Administration (FDA) to ensure their safety and efficacy. Others believe that the current system allows for necessary flexibility and innovation in test development.

Arguments for Stricter Regulation

  1. Concerns about the quality and accuracy of some LDTs
  2. Desire for consistent standards across all Diagnostic Tests
  3. Potential for harm to patients if tests are not properly validated

Arguments for Current Regulation

  1. Flexibility to develop tests quickly in response to emerging public health threats
  2. Promotion of innovation in diagnostic testing
  3. Cost-effectiveness for laboratories and Healthcare Providers

Impact on Hospital Supply and Equipment Management

For hospitals and healthcare facilities, the landscape of LDTs has implications for supply and equipment management. Hospitals must ensure that they have access to the necessary tests to provide quality care to their patients. This means coordinating with suppliers to ensure timely delivery of reagents, equipment, and other resources needed to perform LDTs.

Challenges in Managing LDT Supplies

  1. Keeping track of inventory for a wide range of tests
  2. Ensuring proper storage and handling of sensitive reagents
  3. Balancing the need for tests with limited shelf life

Strategies for Efficient Supply Management

  1. Implementing inventory management systems to track usage and ordering patterns
  2. Establishing relationships with reliable suppliers for quick turnaround on orders
  3. Training staff on proper handling and storage of reagents and equipment

Conclusion

As the use of LDTs continues to grow in the United States, hospitals and healthcare facilities must adapt their supply and equipment management practices to ensure they can meet the demand for these tests. By staying informed about regulatory changes and implementing efficient supply management strategies, hospitals can continue to provide quality care to their patients through the use of LDTs.
