Quality Control

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.

📋 Quality Control Articles


A broad spectrum of analytical and microbiological testing activities are carried out in the Quality Control laboratories, with validated methods and qualified instruments. Common responsibilities include sample analysis, method verification, instrument calibration, environmental monitoring support, investigation of laboratory deviations, data review, and documentation management. QC teams collaborate with Quality Assurance, Production, Warehouse, Engineering and Validation Departments to ensure pharmaceutical products consistently conform to GMP standards and regulatory expectations.

A proper QC testing is essential to ensure the integrity of the product and compliance with FDA, EU GMP, WHO GMP, PIC/S, MHRA and other world regulatory requirements.

Frequently Asked Questions (FAQ)

Q. What is Quality Control in the pharmaceutical industry?

Ans: Quality Control (QC) is a department which tests and release materials, products, samples to ensure that they meet the approved specifications. QC produces analytical data to help make batch release decisions and to ensure product quality, safety, and regulatory compliance.

Q. What are the main responsibilities of a Quality Control department?

Ans: The Quality Control department is responsible for sampling, lab testing, instrument calibration, data review, stability studies, investigation support, reagent preparation and documentation. QC also ensures raw materials, work-in-progress and finished products are ready for release as per the set quality criteria.

Q. Are these Quality Control articles based on GMP requirements?

Ans: Yes. The articles are referenced to the generally accepted principles of GMP and the industry practice in the pharmaceutical industry. They apply to all facilities, including those subject to FDA, EU GMP, WHO GMP, MHRA, PIC/S, Health Canada and other regulatory bodies.
