The quality of medicinal products and active (bio-)pharmaceutical ingredients (APIs) must be tested and documented according to the requirements of the  German Drug Act. According to the German Drug Act, quality is the nature of a drug "as determined by its identity, content, purity and other chemical, physical and biological properties or by the manufacturing process“. Quality control testing of intermediates and final products is performed according to written instructions and validated test procedures, in order to demonstrate compliance with predetermined specifications.
