Analytical validation is the process of confirming that a test or measurement method produces reliable and accurate results. This involves assessing various parameters, such as precision, accuracy, specificity, and sensitivity, to ensure that the method performs consistently under different conditions. It is crucial in fields like clinical diagnostics and pharmaceutical development to ensure that tests can be trusted for decision-making. The goal of analytical validation is to establish that a method is suitable for its intended use. This includes evaluating how well the method detects the target analyte, whether it can differentiate between similar substances, and how stable the results are over time. Proper validation helps maintain quality and safety in products and services.
