I have finalised the demo for the ICH-GCP E6 R3 refresher course. Overall, I liked the content and the interface. I also want to thank Whitehall Train...
About
The Laboratory Deviations, OOS-OOT Investigations and CAPA Training Course provides practical knowledge of identifying, assessing, investigating, documenting, and resolving laboratory deviations, Out-of-Specification (OOS), and Out-of-Trend (OOT) results. The course covers laboratory investigations, hypothesis development, retesting and resampling, data integrity, root-cause analysis, impact assessment, and evidence-based investigation conclusions.
This Laboratory Deviations, OOS-OOT Investigations and CAPA Training & Certification provides practical understanding of Phase I and Phase II investigations, extended investigations, causal analysis, correction versus corrective action, CAPA development, effectiveness verification, recurrence management, and laboratory event trending to support GMP compliance and inspection readiness.
- Quality Assurance (QA) Professionals
- Quality Control (QC) and Laboratory Professionals
- Laboratory Analysts and Supervisors
- GMP Compliance Professionals
- Quality Control Managers
- Validation and Technical Services Professionals
- CAPA and Deviation Management Professionals
- Anyone involved in investigating laboratory deviations, OOS/OOT results, root causes, or CAPA
What you will learn
Understand the fundamentals of laboratory deviations, OOS and OOT results, including definitions, classification, investigation principles, and GMP expectations.
Learn practical approaches to Phase I and Phase II investigations, including hypothesis development, laboratory assessments, retesting, resampling, data integrity, and evidence-based root-cause analysis.
Gain practical knowledge of extended investigations, impact assessment, causal analysis, corrections, corrective actions, CAPA development, effectiveness checks, and recurrence management.
Understand best practices for investigation documentation, laboratory event trending, systemic failure identification, inspection readiness, and maintaining a robust GMP-compliant quality system.
Course Syllabus
- Deviations, OOS, OOT and atypical results distinguished
- Why OOT has no single harmonised definition; justifying OOT limits
- Invalid assays and system-suitability failures are not automatically an OOS
- A laboratory deviation can occur without an OOS
- Triage and classification of laboratory events
- Early data-integrity signals
- Immediate and interim actions on discovering a result
- Preserving samples, solutions, data and evidence
- Contemporaneous, ALCOA+ recording
- Phase I initial laboratory assessment and the objective analyst discussion
- Reviewing calculations, transcription and sample preparation
- Reviewing standards, reagents, equipment, environment and method execution
- Reviewing chromatography, reintegration and audit trails
- Developing scientifically plausible hypotheses
- Testing hypotheses; avoiding retrospective hypothesis creation
- When a result may be invalidated — documented assignable cause
- Justifying and defining a controlled retest plan
- Justifying resampling with a defensible rationale
- Testing into compliance is unacceptable; a passing retest does not invalidate
- Considering all valid results; averaging must not conceal an OOS
- Triggering and running a Phase II extended investigation
- The laboratory-manufacturing investigation interface
- Evaluating manufacturing and product impact
- Other affected batches, products and methods
- Stability and clinical/study impact
- Batch-disposition and product-impact decisions
- Structured RCA — 5-Whys and fishbone (Ishikawa)
- Assignable cause versus most-probable cause
- Human error is a description, not a stand-alone root cause
- Distinguishing correction, correction of the record and corrective action
- Isolated versus systemic failure
- Documenting the root-cause conclusion and its evidence
- Designing CAPA proportionate to root cause, risk and systemic impact
- Retraining alone is not an adequate CAPA
- Defining measurable CAPA effectiveness criteria
- CAPA closure is not the same as CAPA effectiveness
- Separate evaluation and escalation of data-integrity concerns
- Verifying effectiveness and preventing recurrence
- Worked chemistry OOS case (fictional data)
- Stability OOT investigation
- Pharmaceutical microbiology and sterility/bioburden failures
- Environmental-monitoring excursions
- Contract-laboratory discrepancies
- Data-integrity case — shared accounts and uncontrolled reintegration
- Writing a clear, defensible investigation report
- Reviewing investigation reports for quality and closure
- Trending laboratory events and reviewing trends
- Identifying recurring and systemic failures
- Management review of investigations
- Preparing for regulatory inspection and self-assessment
- Ten behaviours of a strong laboratory investigation
- The end-to-end investigation lifecycle
- 📘 Bonus:Laboratory Deviations, OOS-OOT Investigations and CAPA eBook (Free with purchase)
