Laboratory Drug Testing: Methods, Concepts and Case Studies
The focus of this presentation is on understanding the laboratory’s role drug testing in the context of therapeutic drug monitoring, pain manangement, and drug abuse. Testing methods and principles including immunoassays and various mass spectrometry techniques are highlighted and comparisons are made between urine and serum regarding detection times and drug metabolite targets. In the context of several case studies, drug metabolism is reviewed and the broader concept of screening vs. confirmation testing is discussed.

After this presentation, participants will be able to:
- Gain general knowledge of the technology available for drug testing along with each technology’s benefits and limitations.
- Understand how drug concentration is impacted by the testing matrix (or specimen type), biological clearance rates, and dose vs. collection time.
- Understanding and interpreting lab results when they are inconsistent with expectations.
