Webinar Recording: Developing a Comprehensive Urine Pain Panel

28 March 2017

This webinar discusses considerations for developing robust sample preparation methods for acidic, basic and neutral drugs for pain management and compliance testing in hydrolyzed urine specimens. Method development strategies depending upon the drug analytes of interest are presented.

There has been increased interest in the clinical laboratory to develop comprehensive LC-MS/MS assays for urine drug testing, with fifty or more drugs and metabolites from multiple drug classes in a single method. These panels can increase throughput and improve laboratory efficiency, but also create many challenges. 

Key Learnings

  • Learn to develop better methods for large drug panels in urine based on the drugs of interest and their properties
  • Understand the effect of pH and logP on retention and recovery
  • Understand how to optimize enzyme and hydrolysis conditions
  • Learn when to choose supported liquid extraction (SLE), reverse-phase solid phase extraction (SPE), and ion exchange SPE

Who is this For?

Chemists and technologists, laboratory supervisors and managers, medical directors and R&D scientists in laboratories who develop, validate, or perform assays for urine drug testing.
