Core Validation Parameters Under ICH Q2R2

ICH Q2R2 requires you to demonstrate accuracy within 98.0-102.0% of the theoretical value and precision with RSD ≤2.0% for your analytical methods.

You’ll need to verify specificity by proving your method can distinguish the analyte from impurities, excipients, and degradation products without interference.

Robustness evaluation demands you test how small, deliberate variations in method parameters affect results, ensuring your method performs reliably under typical laboratory conditions.

Accuracy and Precision Requirements

Whenever analysts develop analytical methods, accuracy and precision stand out as critical validation parameters that determine method reliability.

ICH Q2R2 guidelines establish specific accuracy thresholds that require your analytical method to demonstrate recovery rates between 98-102% of the true value for drug substances and 95-105% for drug products.

Precision standards under these guidelines involve evaluating repeatability, intermediate precision, and reproducibility. You’ll need to achieve relative standard deviations (RSDs) below 2% for assays and below 5% for impurity testing.

When validating your method, you must perform at least nine determinations across three concentration levels to establish accuracy, while precision requires multiple measurements under identical conditions.

These stringent requirements guarantee your analytical method delivers consistent, trustworthy results that regulatory agencies will accept.

Specificity and Robustness Evaluation

Determining whether your analytical method can correctly identify the analyte without interference from other components represents the cornerstone of specificity validation under ICH Q2R2.

You’ll need to demonstrate that your method distinguishes the analyte in the presence of impurities, degradation products, and matrix components through well-designed specificity challenges.

Robustness testing evaluates how reliable your method remains when faced with small, deliberate variations in procedural parameters.

You should investigate critical factors like mobile phase composition, pH, column temperature, and flow rate to identify potential vulnerabilities.

This assessment helps you establish appropriate system suitability criteria and method controls.

Expanded Scope for Modern Analytical Technologies

The revised ICH Q2R2 guidance has expanded to address spectroscopic techniques that now offer unprecedented molecular characterization across diverse sample matrices.

You’ll find new validation approaches for biomarker detection technologies that enable more sensitive quantification of complex biological markers than previously possible.
