Quality assurance of health products

Purpose

The quality of health products has to be ensured from manufacturing up to the point of use. Quality assurance (QA) is an overarching element to the whole PSM cycle, beyond the prequalification of health products, to ensure compliance with WHO and national standards. Transportation, storage, distribution and use conditions impact the quality of health products.

Key concepts

Quality assurance

“Quality assurance is a wide-ranging concept covering all matters that individually or collectively influence the quality of a product. It is the totality of the arrangements made with the object of ensuring that pharmaceutical products are of the quality required for their intended use.” – World Health Organization

Prequalification

“The activities undertaken in defining a product or service need, seeking expressions of interest from enterprises to supply the product or service, and examining the product or service offered against the specification and the facility where the product or service is prepared against common standards of good manufacturing practice (GMP). Prequalification is required for all pharmaceutical products regardless of their composition and place of manufacture/registration.” – World Health Organization

Quality control

“Quality control covers all measures taken, including the setting of specifications, sampling, testing and analytical clearance, to ensure that starting materials, intermediates, packaging materials and finished pharmaceutical products conform with established specifications for identity, strength, purity and other characteristics.” – World Health Organization
