The accuracy of a method must be determined across its range of application. The accuracy of an analytical method is the closeness to the true or accepted reference value. Accuracy refers to the closeness of test results obtained from an analytical method to the true value. Method validation incl udes determining any cross reactivity with other known entities. Accuracy is often considered as a qualitative term . Establishing documented evidence which provides a high degree of assurance that a specific process (analytical test method) will consistently produce a product (assay result) meeting its predetermined specifications and quality attributes (accuracy, precision, etc.) The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. 2010. There are different approaches for measurement uncertainty estimation, but in practice the approach based on validation data is often the most convenient. 24 Retain samples The ICH document on validation methodology recommends accuracy to be assessed using a minimum of nine determinations over a minimum of three concentration levels covering the specified range (e.g., three concentrations/three replicates each). Pharm Anal Acta. Results from method validation can be used to judge the quality, reliability and consistency of anal ytical results; it is an integral part of any good analytical practice. The worktable in this method is a 2x2 contingency table where positive and negative results from candidate test are measured “against” diagnostic accuracy criteria. Method Development and Validation for estimation of MoxifloxacinHCl in tablet dosage form by RP-HPLC method.
