About us

The Joint Committee for Traceability in Laboratory Medicine (JCTLM):


The JCTLM was established in 2002 through a declaration between the International Bureau of Weights and Measures (BIPM), the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) and the International Laboratory Accreditation Cooperation (ILAC) in response to the implementation of the European Community Directive 98.79/EC on in vitro medical devices.

The JCTLM is an international consortium that promotes the global standardization of clinical laboratory test results, and provides information on reference materials, reference measurement methods and services that are available from around the world. 

The aim of JCTLM is to support world-wide comparability, reliability and equivalence of measurement results in laboratory medicine, for the purpose of improving health care and facilitating national and international trade in in vitro diagnostic devices, by:

  • promoting the concept of traceability of measurement results to the Système International d'Unités (SI) or, where necessary, to other internationally agreed references;
  • evaluating reference materials, reference measurement procedures and reference measurement services for laboratory medicine with respect to conformity with appropriate international standards;
  • producing educational materials and activities promoting the value of traceability in laboratory medicine and raising awareness amongst stakeholders;
  • promoting close links between Reference Laboratories in Laboratory Medicine and National Metrology Institutes;
  • facilitating the identification and prioritization of measurands requiring international traceability and comparability and thereby encouraging appropriate organizations to accept responsibility for the development of suitable reference methods and measurement procedures and certified reference materials;
  • encouraging thein vitro diagnostic (IVD) industry to apply the agreed reference measurement systems;
  • encouraging EQAS organizers to apply the agreed reference measurement systems. 

The JCTLM has some 40 Member organizations spread across three categories:

  • Executive Committee Members
  • National and Regional Members
  • Stakeholder Members

A list of the current JCTLM Members may be found in the ‘Partners’ section of this website. 

The main output of the JCTLM is the global database of higher order reference materials; reference measurement methods/procedures; and reference measurement services. This database is freely available. Full details of the JCTLM database, including content and operation may be found at www.bipm.org/jctlm/


The JCTLM Working Group for Traceability, Education and Promotion (WG-TEP): 

In order to fulfil the third component of its aim the JCTLM created the WG-TEP in 2016.  This website has been created by WG-TEP and is its main forum for making available support materials and interacting with JCTLM stakeholders and individuals who are interested in the importance of traceability in laboratory medicine as a driver of accurate patient results. 

The aim of WG-TEP is to produce and promote educational materials to demonstrate the value of traceability in laboratory medicine as a means to reduce between method variability in the interests of improved clinical outcomes and patient safety. 

The specific roles of WG-TEP are:

  • Organisation of the two-yearly JCTLM Members Meeting
  • Organisation of JCTLM scientific and educational meetings, symposia and conferences
  • Assessment of applications for meetings to be held with JCTLM auspices
  • Production of educational materials to promote the value of traceability in laboratory medicine
  • In conjunction with the JCTLM Secretariat production of the annual JCTLM e-newsletter
  • Production and maintenance of a ‘traceability’ website, which contains information, resource material and regular news items about the role of traceability in laboratory medicine. This website will link to the JCTLM database and will be available to link to the websites of all JCTLM members
