The validation procedure in this particular article is based on requirements for EU multistate registration.
Wegscheider (13) has published procedures for method validation with a special focus on calibration, recovery experiments, method comparison and investigation of ruggedness. (14) have described how analytical methods are validated in a Japanese QC laboratory.
The preparation and execution should follow a validation protocol, preferably written in a step-by-step instruction format.
Possible steps for a complete method validation are listed in Table 1.USP Reference Standards are not intended for use as drugs, dietary supplements, or medical devices.Directions for storage and use are on the label of each Reference Standard.It is not always necessary to validate all analytical parameters that are available for a specific technique.For example, if the method is to be used for qualitative trace level analysis, there is no need to test and validate the method’s limit of quantitation, or the linearity, over the full dynamic range of the equipment.Users must ascertain that the Reference Standards they are using are a "Current lot" or a "Previous lot" within the valid use date.
