Further information


This training on pharmaceutical laboratory OOS investigations will explain how to recognize and address atypical or out of specification results, using approaches which have been recommended by regulatory authorities, performing appropriate investigations.


Investigations into unexpected results are usually time consuming and fraught with anxiety, as well as being subject to Regulatory inspection. Using a Root Cause Analysis approach can reduce the time necessary to complete the investigation and simultaneously help, by pointing to appropriate Corrective and Preventative Action (CAPA) reduce the probability that additional OOS results from the same cause will be observed.

This webinar will point out some of the goals of effective investigations, and how you can use Root Cause Analysis and Corrective and Preventive Actions to accomplish these goals.

Upon completion of this course the learner should be able to:

  • Be familiar with various terms associated with investigations of atypical or out of specification results, and how to document those investigations.
  • Be familiar with the FDA Guidance for Industry on Investigating Out-of-Specification (OOS) Test Results for Pharmaceutical Production and how to apply it in laboratory situations.
  • Be able to create a Laboratory Investigation Checklist and effectively document an investigation, including rationale and results.
  • Know the importance of finding the true root cause and some techniques to assist in finding it.
  • Know the importance of Corrective and Preventative Action (CAPA) and be able to identify appropriate CAPAs.
  • Understand practical strategies to utilize outcomes from investigations for continuous improvement and reduction of future OOS results.


  • What Constitutes An Atypical or Out of Specification Result?
  • The FDA Guidance for Industry on Investigating OOS Test Results
  • Phase I: Initial Laboratory Investigation
  • Phase II: Full Scale Investigation
  • Tools for finding the Root Cause
    • Testing the hypotheses regarding potential root causes
    • Retesting
    • Considering Other Batches
  • Corrective and Preventive Action (CAPA)
  • Documenting the Investigation
  • Case Study
  • Questions and discussion
