Under ISO 17025, what does validation provide?

Validation under ISO 17025 is fundamentally about providing objective evidence that specific requirements are met, particularly in relation to testing and calibration processes. This aspect of validation ensures that the methods and processes used in the laboratory are appropriate for their intended use and that the results are reliable and accurate. It involves systematically verifying that the procedures used achieve the desired performance characteristics and adhere to specified standards.

While aspects like proof of process efficiency and confirmation of staff competence are crucial to the overall functioning and reliability of a laboratory, they are not the primary focus of validation as defined by ISO 17025. Instead, validation specifically aims to demonstrate that the outcomes of laboratory practices align with established criteria and regulatory requirements, serving as a vital component in maintaining quality assurance in laboratory operations.
