ILAC – JCTLM Partnership


The Joint Committee for Traceability in Laboratory Medicine (JCTLM) was established by the International Bureau of Weights and Measures (BIPM), the International Federation for Clinical Chemistry and Laboratory Medicine (IFCC), and the International Laboratory Accreditation Cooperation (ILAC). The goal of the JCTLM is to provide a worldwide platform to promote and give guidance on internationally recognized and accepted equivalence of measurements in Laboratory Medicine and traceability to appropriate measurement standards.


Declaration of Cooperation

The JCTLM was created in 2002 through a Declaration of Cooperation between the BIPM, IFCC and ILAC. The Declaration of Cooperation was revised in 2012, following the revision of harmonized standards relating to higher order reference materials and methods, and re-signed in November 2019.


JCTLM Database

The JCTLM Database: Laboratory Medicine and in vitro diagnostics is a database of higher-order reference materials, measurement methods/procedures and services.
