JCTLM: Declaration of Cooperation between the BIPM, the IFCC and ILAC

The JCTLM was created in 2002 through a Declaration of Cooperation between the International Bureau of Weights and Mesures (BIPM), the International Federation for 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 Declaration of Cooperation was revised in 2019, to facilitate expansion of the JCTLM Executive Committee to include additional organizations in its membership from further branches of laboratory medicine, and re-signed in December 2019.

The BIPM, the IFCC, and the ILAC agree to cooperate for the operation of the Joint Committee for Traceability in Laboratory Medicine, with the acronym JCTLM.

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.
