CTICC room location: 1.6


Manufacturers of IVDs, procurement agencies, policy makers, national disease programme managers, managers of laboratories and other testing services.


The WHO Prequalification of In Vitro Diagnostics (PQDx) aims at ensuring the quality of commercially available IVDs through a comprehensive process including a review of the product dossier to support manufacturers’ claims, a performance evaluation to verify performance and operational characteristics and an on-site inspection to assess the quality management system under which products are manufactured. In settings where regulatory capacity is lacking, the outcomes of the prequalification process may provide a source of unbiased, scientifically sound evidence to inform procurement decisions for a continuously expanding range of analytes.

The Emergency Use Assessment and Listing (EUAL) procedure was developed in 2014 in response to the largest Ebola epidemic in history, affecting multiple countries in West Africa. The aim of the procedure is to assess candidate IVDs needed as part of the response to a Public Health Emergency of International Concern (PHEIC) and to expedite their availability. It is intended to advise interested procurement agencies and Member States on the suitability for use of a specific IVD, based on a minimum set of available quality, safety, and performance data. On 5 February 2016, the EUAL procedure was expanded to include IVDs intended for Zika virus disease diagnosis.

WHO will present an update on the WHO Prequalification of IVDs and will present the work performed under the EUAL procedure for Ebola and Zika virus diseases.


  1. Briefing on the progress and expansion of WHO Prequalification of In Vitro Diagnostics,
  2. Presentation of the Emergency Use Assessment and Listing procedure (EUAL): work performed for Ebola IVDs and progress on Zika virus IVDs.
