## About this white paper

Analytical method validation is essential to demonstrate that a method is suitable for its intended purpose. Before validation can begin, both the method and its intended use need to be clearly defined, from the analytes and expected concentration levels to the sample matrix and type of result required.

This expert article walks you through the key characteristics used to establish whether an analytical method delivers consistent, reproducible and reliable results. It explains how parameters such as specificity, linearity, precision, accuracy, range, detection and quantitation limits, and robustness contribute to a well-founded validation approach.

You'll also get an overview of the relevant validation guidance, including ICH Q2 and applicable pharmacopoeial requirements, helping you understand not just what to validate, but what to consider when building your validation strategy.

## Key Takeaways

✓ **Define intended use before you validate.** Understand why analytes, concentration levels, sample matrix, potential interferences and the required type of result should be established before method validation begins.

✓ **Demonstrate specificity and linearity.** Learn how to show that your method can distinguish the analyte of interest from potential interferences and produces an appropriate response across relevant concentrations.

✓ **Understand precision and accuracy.** Explore how repeatability, intermediate precision and reproducibility are assessed, and how accuracy demonstrates the closeness of your results to the true or theoretical value.

✓ **Establish the right analytical range.** See how linearity, accuracy and precision come together to determine the range over which your analytical procedure can reliably be applied.

✓ **Know your detection and quantitation limits.** Understand the difference between LOD and LOQ and the approaches that can be used to determine them.

✓ **Don't overlook robustness and system suitability.** Learn why deliberate variations in method parameters should be considered and how system suitability testing helps confirm that the complete analytical system performs as expected.
