Alternatively, after a firm has proven a general strategy for earning the changeover concerning tests, it may post the method for evaluate in a PAS—comparability protocol (CP). The CP really should explain, intimately, the methods accustomed to changeover concerning assays and the acceptance criteria utilized to establish the equivalence of the new technique. Just after acceptance with the CP, outcomes of implementation in the CP might be directed to get described in a very reduced reporting classification (Nutritional supplement—Changes Getting Effected or Once-a-year Report or Particular Report (21 CFR 314.
