Quality Control (QC) is one of the most important steps in the pharmaceutical production process that is used to guarantee that raw material, packaging material, in-process samples, finished product and stability samples are tested and released to the market. The QC department is of great importance in ensuring product quality, regulatory compliance and, ultimately, patient safety.
