PART ONE: Key Principles of Clinical Drug Testing in Medication-Assisted Treatment (MAT)

30 Sep 2025

Clinical drug testing plays a vital role in supporting safe and effective care for patients undergoing medication-assisted treatment (MAT) for substance use disorder (SUD), such as opioid use disorder (OUD). As part of Labcorp’s commitment to improve patient and public health outcomes, we hosted a series of webinars focused on clinical drug testing in MAT.

What will I learn about MAT in part one of this webinar?

Our toxicology experts, including an addiction medicine provider, cover topics including:

  • Evidence-based best practices, toxicology testing and MAT in supporting recovery from SUD, including OUD
  • How drug testing improves compliance
  • Advanced specimen validity
