Usp assay


The Assay is a separate test from <905>. It uses the analysis of a composite from multiple units. <905> evaluates uniformity of dose with the limit on the Acceptance Value and an acceptable range of individual values if testing proceeds to 30 units. In neither of these tests is there a requirement that individual results conform to the Assay limits, typically 90% to 110% of label claim In assay of a drug in a formulated product, accuracy may be determined by application of the analytical method to synthetic mixtures of the drug product components to which known amounts of analyte have been added within the range of the method. If it is not possible to obtain samples of all drug product components, it may be acceptable either to add known quantities of the analyte to the drug.
