This session highlights how collaborative relationships between pharmacy and laboratory teams can drive better patient outcomes. Therapeutic Drug Monitoring (TDM) delivers the greatest value when pharmacy and laboratory teams work in partnership. This webinar will explore how interdisciplinary collaboration can optimize patient care and support the successful implementation of TDM programs.
Join Dr. Megan Ehret, Psychiatric Pharmacist, and Dr. Vincent De Guire, Laboratory Director, for a candid, practical conversation on integrating clozapine TDM into clinical practice. Drawing on real-world experience, Dr. De Guire will share:
- Strategies to align laboratory and clinical teams
- How to navigate common pitfalls when changing test methods
- How to answer the question: Which TDM method is “better?”
- Tips for advocating effectively for the tests your patients need
While clozapine serves as the primary example, the insights shared will apply broadly across TDM use and interactions with laboratory leadership. Bring your questions—this is your chance to get answers to what you have always wanted to ask the lab.
*This webinar was live on June 18, 2025 and the recording will remain available to registrants through September 18, 2025. Please note that around the 52-minute mark, during the Q&A session, the recording will continue with audio only and no video.
