Technical Guidance Series 6 (TGS-6) for WHO Prequalification – Diagnostic Assessment: Panels for Quality Assurance and Quality Control of in Vitro Diagnostic Medical Devices
(2017; 57 pages)


The WHO Prequalification Programme is coordinated through the Department of Essential Medicines and Health Products. WHO prequalification of in vitro diagnostic medical devices (IVDs) is intended to promote and facilitate access to safe, appropriate and affordable IVDs of good quality in an equitable manner. The focus is on IVDs for priority diseases and their suitability for use in resource-limited settings. The WHO Prequalification Programme undertakes a comprehensive assessment of individual IVDs through a standardized procedure that is aligned with international best regulatory practice. It also undertakes post-qualification activities for IVDs to ensure ongoing compliance with prequalification requirements.

Products that are prequalified by WHO are eligible for procurement by United Nations agencies. The products are then commonly purchased for use in low- and middle-income countries.

The Technical Guidance Series was developed following a consultation – held on 10–13 March 2015 in Geneva, Switzerland – which was attended by experts from national regulatory authorities, national reference laboratories and WHO prequalification dossier reviewers and inspectors. The guidance series is a result of the efforts of this and other international working groups.

This guidance is intended for manufacturers interested in WHO prequalification of their IVD. It applies in principle to all IVDs that are eligible for WHO prequalification for use in WHO Member States. It should be read in conjunction with relevant international and national standards and guidance.
