Method validation is the process used to confirm that the analytical procedure employed for a specific test is suitable for its intended use. Can some one help me in establishing protocol for validation of invitro samples and biological samples. HPLC. Manufacturers should choose the validation protocol 152 and procedures most suitable for testing of their product. Method validation in chromatography must be carried out as per the validation protocol is given by the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) or The United States Pharmacopeia (USP) and British Pharmacopoeia (BP).
