1. Purpose
To define a structured process for the transfer of validated analytical methods from the R&D or Analytical Development Laboratory (ADL) to the Quality Control (QC) laboratory for routine use in the analysis of raw materials, intermediates, and APIs.
2. Scope
This SOP applies to the transfer of compendial and non-compendial analytical methods developed and validated for quality
testing of materials used and produced in API manufacturing. It covers comparative testing, documentation, training, and approval steps required prior to implementation in QC.
3. Responsibilities
- Method Development Scientist: Provide all validated method details, protocols, and demonstration data.
- QC Analyst: Perform comparative testing and data recording as per transfer protocol.
- QC Reviewer: Verify compliance of results and review of transfer reports.
- QA Officer: Approve method readiness and control implementation in routine use.
4. Accountability
The QC Head is accountable for ensuring that analytical methods are transferred, verified, and adopted into routine QC operations as per GMP and regulatory requirements.
5. Procedure
5.1 Initiation of Method Transfer
- The R&D/ADL team shall submit the following to the QC department:
- Validated method protocol
- Validation summary report
- Reference standards and working solutions (if applicable)
- Training presentation or demonstration session
- The QC Head, in coordination with QA, initiates a Method Transfer Protocol (Annexure-1) outlining:
- Test parameters
- Acceptance criteria
- Number of analysts
- Number of runs and sample types
5.2 Comparative Testing in QC
- QC performs side-by-side or replicate testing of 3–5 sample sets using:
- The method provided
- Standard test materials with known values
- Record:
- Accuracy, precision (repeatability, intermediate precision)
- Specificity, linearity (if applicable)
- System suitability
- All observations must be documented in the Method Transfer Log (Annexure-2).
5.3 Evaluation and Reporting
- Compare observed data to validation results and acceptance limits.
- If results meet acceptance criteria:
- Prepare Method Transfer Report (Annexure-3)
- Obtain QA review and approval
- If not acceptable:
- Investigate root cause (analyst error, equipment variability, material quality)
- Repeat transfer only after corrective action
5.4 Training and Implementation
- Train all QC personnel on the transferred method using a Method Training Record (Annexure-4).
- Ensure reference standards, reagents, and equipment for the method are available and qualified.
- Update the STP index, method directory, and QC master schedule.
5.5 Final Approval and Routine Usage
- Upon successful transfer, QA issues a formal approval memo for method implementation.
- The method becomes part of routine QC testing activities.
- Retain all related documents in the Method Transfer Dossier for audit readiness.
