Introduction to a WHO Model List of Essential In Vitro Diagnostics (the EDL)

EDL Context
WHO recognises that IVDs are an essential
component to:
• Advance universal health coverage
• Address health emergencies
• Promote healthier populations,

(2019-2023).

Why an EDL and why now?
• The EML is among the most valued tools
developed by WHO. An EDL has similar
potential.
• The crucial role of IVDs is becoming widely
acknowledged and is growing rapidly
(while still fragmented). Countries will
need guidance for selection, procurement
and usage decisions.
• There is strong support from the Global
Health community for an EDL.

The EDL sets out a group of IVD tests that are recommended by WHO for use at
various levels of a tiered laboratory system in-country
The EDL is expected to:
1. Provide guidance to Member States who are developing and/or updating lists of
national essential IVDs for defining universal health coverage interventions, as
well as selecting and implementing such IVDs
2. Inform United Nations (UN) agencies and non-governmental organizations
(NGOs) who support selection, procurement, supply, donations or provision of
in vitro diagnostics
3. Provide guidance to the medical technology private sector on the diagnostics
priorities needed to address global health issues

Objectives of the EDL
EDL scope and oversight
5
First Edition: High priority infectious diseases
(TB, malaria/G6PD, HIV, hepatitis B & C, HPV
and syphilis)
Plus general laboratory tests
No brand names or specific products
Annual Review: Add tests for both infectious
diseases and NCDs
Process generally similar to that
for EMLs but adapted for IVDs

General principles for inclusion of IVDs in the list
• Public health relevance
• Evidence based
• Free of conflict of interests
Process generally similar to the EMLs but adapted for IVDs (e.g.: often low
level of evidence, especially in LMICs, IVDs characteristics vary based on
the level of the health care facility)
6
Priority disease areas for consideration in the 2nd edition of the
EDL are Emergency tests, AMR, NCD’s & NTD’s
What does the EDL look like?
• The first edition of the list published on 15 May 2018 includes more than
100 tests
• The preface to the EDL describes all requirements to implement the list
and encourages member states to adapt the list to their own needs
• Tests are separated to show which tests can be used in primary care
settings where no labs are available, and which tests require lab support
• For each test, a link is provided to any WHO-prequalified products if
available, as well as any relevant WHO supporting documents
• Dedicated page on the WHO web site is being created to centralize all
available information supporting the implementation of the list

Member States will need to consider a variety of factors in order to adapt the EDL to local
circumstances: Examples are:
• Local demographics and pattern of diseases
• Treatment facilities
• Training and experience of available personnel
• Local testing gaps
• Supply chain
• Quality assurance capacity
• Local availability of treatments
• Financial resources
• Environmental factors
WHO is compiling information that supports the selection and use of IVDs on the EDL, on a
single web site

1st WHO list of diagnostic tests unveiled to boost diagnosis accuracy Source: Xinhua| 2018-05-16 04:35:25|Editor: Mu Xuequan GENEVA, May 15 (Xinhua) -- The
World Health Organization (WHO)
published Tuesday its first catalogue
of tests needed to diagnose the most
common health conditions as well as
a number of priority diseases to
improve diagnosis and treatment
outcomes.
The Essential Diagnostics List
concentrates on in vitro tests, which
are tests of human specimens like
blood and urine.
The WHO Model List of Essential In Vitro Diagnostics
unveiled on 15 May 2018. Some news articles

Conclusion: The need to implement the EDL
Ultimately, effective medical
practice relies on diagnostic
capabilities
The EDL is only a list until it is
adopted by countries to support
access to in vitro diagnostics
