A Step-by-Step Guide for Method Validation
- 1. A Step-by-Step Guide for Method Validation
- 2. What is Validation? • Methods validation is the process of demonstrating that analytical procedures are suitable for their intended use‐Guidance for Industry • Validation is a process-risk will determine the effort High Risk • Total validation Moderate risk • Testing, documentation Low risk • Testing the change
- 3. Validation of Analytical Methods-Key Steps Preparation Experimentation Transferring method Documentation
- 4. Step 1- Preparation • Develop validation project plan • Define purpose/scope of method (performance criteria) • Define and verify performance of equipment • Qualify/validate materials • Qualify/train operator
- 5. Step 2- Experimentation • Perform validation experiments- may have to change either equipment or limits • Develop SOPs for executing the method in routine • Define type and frequency of system suitability tests and/or analytical quality control (AQC) checks • Define change control procedure • Document validation experiments and results
- 6. Step 3- Transferring Methods to Routine Laboratories • Designate project owner • Develop procedure on how to use method • Develop system suitability tests (test procedure, frequency, acceptance criteria) • Define transfer tests and acceptance criteria in the routine • Train routine lab analyst in development lab • Repeat 2 critical method validation tests in routine lab • Analyze at least three samples in development and routine lab • Analyst in routine lab should give frequent feedback
- 7. Step 4- Documentation for the FDA Validation report and supporting documentation: • Objective, scope • Methodology • Materials • Equipment • Validation data • Supporting documentation (chromatograms, spectra) • Transfer to routine protocol • Reference to SOP
