Cross-validation is a comparison of validation parameters when two or more bioanalytical methods are used to generate data within the same study or across different studies. The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled “Bioanalytical Method Validation.” The validation parameters are described, together with an example of validation methodology applied in the case of chromatographic methods used in bioanalysis, taking in account Method validation 5.1 Validation should be performed in accordance with the validation protocol. 1244 0 obj <>stream According to FDA’s non-binding guidelines, method development should put a premium on some bioanalytical parameters. A syntetic discussion on bioanalytical methods validation is presented from the point of view of regula- tory documents, scientific articles and books. In the last decade, similar discussions have been going on in the closely related field of phar- macokinetic studies for registration of pharmaceuticals.
