Investigating Out-of-Specification (OOS) Test Results in the Laboratory; FDA Guidance and Latest Expectations - Webinar (Recorded)

  • Webinar

  • 120 Minutes
  • November 2023
  • World Compliance Seminar
  • ID: 5794171

Inadequate investigation of out-of-specification (OOS) results in the laboratory is a common observation cited in FDA 483s and Warning Letters. It is clear that regulatory investigators throughout the world are looking at laboratory operations very closely.

The objective of this live training webinar is to develop an understanding of how a compliant laboratory handles the investigation of OOS test observations and how the laboratory interfaces with other units through the laboratory investigation process. The interactive live discussion will be based on the FDA guidance on handling OOS laboratory results and to provide a clear process for compliant laboratory OOS investigations.
