Prequalification Guidance

Prequalification Guidance


Prequalification guidance documents relating to in vitro diagnostics (IVDs) represent WHO's current thinking with respect to:

  • IVDs eligible for WHO prequalification assessment
  • the intended use settings where the WHO prequalified-IVDs will be used
  • the intended users of WHO-prequalified IVDs.

The guidance documents are issued in support of WHO's objective to improve access to safe, effective and quality IVDs. They are intended to help assist IVD manufacturers understand the requirements for WHO prequalification assessment and/or procurement by WHO and other UN agencies. They should be consulted together with relevant Technical Specifications Series and Technical Guidance Series documents. 

How to provide input for guidance development

Guidance documents are published in draft on the WHO prequalification website for a specified public comment period. For most documents, the comment period is two months. However, the length of time may vary, depending on the document. Public comment tables are made available for each document.

Comments should be submitted to: diagnostics@who.int.
