analytical method verification parameters

Compendial methods should be verified to demonstrate the suitability of laboratories to successfully run the method and when methods are transferred between laboratories successful transfer should be demonstrated through testing or a transfer waiver, if justified. Leaflet: Verification of Pharmacopeia Methods . 3.2 Pharmacopoeial methods used for determination of content or impurities in pharmaceutical products should also have been ... and should show the reliability of an analysis when deliberate variations are made in method parameters. for the assay, the two results should be compared; for the impurity tests, the impurity profiles should be compared. the method in terms of matrix, analytical parameters, concentration level(s), etc. The response factor of the drug substance can be used. If DL is determined based on visual evaluation or based on the signal to noise ratio, the presentation of the relevant chromatograms is considered acceptable for justification. Aspects - Dependent on type of test - For chromatographic methods: tailing factor, rel. This approach can only be applied to analytical procedures that exhibit baseline noise. Impurities are not available:- 2.2 Specifications and standard test methods in pharmacopoeias (“pharmacopoeial methods”), or suitably developed specifications or test methods (“non-pharmacopoeial methods”) as approved by the national drug regulatory authority may be used. Spams/ Promotional links are not allowed and shall be deleted upon review. Standard solutions should be prepared as per method  a minimum of 6 determinations at 100% of the test concentration or  a minimum of 9 determinations covering the specified range for the procedure (e.g., 3 concentrations/3 replicates each); Method Precision to reproduce results through the same method with six samples. 3. • specific intended use = analytical requirement • objective evidence = experimental data (method performance parameters) ... – verification of the performance of previously validated methods ... – make deliberate changes to method parameters – observe effect on results • Control key parameters 5.2 Justification should be provided when non-pharmacopoeial methods are used if pharmacopoeial methods are available. : pharmacopoeial method or other validated analytical procedure (independent procedure). Analytical Method Transfer Checklist: The receiving laboratory shall verify that all equipment/system(s) required to perform the method testing is available The receiving laboratory shall verify that all equipment is qualified and properly calibrated – laboratory equipment/system(s) are in compliance with all applicable regulations and user specifications 2 Department of Biotechnology, SASTRA University, Tanjavur, Tamilnadu, India. Lecture 5: Transfer of Analytical … The method’s performance parameters and limits should be based on the intended use of the method. Therefore, meaningful experimental designs including system suitability parameters must be planned for the intended use of the procedure. Several methods for determining accuracy are available: 2. they must be validated. Based on the Standard Deviation of the Response and the Slope The detection limit (DL) may be expressed as: Method transfer objectives Justification should include data such as comparisons with the pharmacopoeial or other methods. Several approaches for determining the quantitation limit are possible, depending on whether the procedure is a non-instrumental or instrumental. 3rd. Parameters that are evaluated during method development are specificity, linearity, limits of detection (LOD) and limits of quantitation (LOQ), range of accuracy, and precision. In the case of compendial methods, revalidation may be necessary in the following cases: a submission to the USP of a revised analytical method; or the use of an established general method with a new product or raw material (see below under Data Elements Required for Assay Validation).
