Investigating Out-of-Specification (OOS) Course Description

August 19, 2025, Tuesday

Live, Interactive Training Webinar

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.

Webinar Takeaway

• The requirements for laboratory OOS investigations. 
• Latest Regulatory expectations.
• The laboratory OOS investigation process.
