For drug, animal drug, and Organic goods, the transition to a completely new method needs to be submitted in a prior approval complement (PAS). Alternatively, the moment a business has recognized a normal technique for generating the transition in between tests, it may submit the tactic for evaluation inside of a PAS—comparability protocol (CP). The CP must describe, in detail, the approaches used to transition concerning assays plus the acceptance criteria used to determine the equivalence of the new approach.
