Quality control includes sampling, setting specifications for and testing of raw materials, intermediates and finished products. All supplies that come into the factory have to be carefully controlled. Raw materials must meet the specification set by the company, and all batches are tested against this specification. 

To safeguard the quality and efficacy of the medicines being produced, teams of analytical chemists, microbiologists, environmental scientists and safety experts work closely with manufacturing colleagues to see that every medicine that’s produced is of the highest standard possible. They also check that the bi-products of the process do not adversely affect the local environment.
