title: The Joint Committee for Traceability in Laboratory Medicine (JCTLM) - its history and operation.
abstract: The Joint Committee for Traceability in Laboratory Medicine (JCTLM) was formed to bring together the sciences of metrology, laboratory medicine and laboratory quality management. The aim of this collaboration is to support worldwide comparability and equivalence of measurement results in clinical laboratories for the purpose of improving healthcare. The JCTLM has its origins in the activities of international metrology treaty organizations, professional societies and federations devoted to improving measurement quality in physical, chemical and medical sciences. The three founding organizations, the International Committee for Weights and Measures (CIPM), the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) and the International Laboratory Accreditation Cooperation (ILAC) are the leaders of this activity. The main service of the JCTLM is a web-based database with a list of reference materials, reference methods and reference measurement services meeting appropriate international standards. This database allows manufacturers to select references for assay traceability and provides support for suppliers of these services. As of mid 2015 the database lists 295 reference materials for 162 analytes, 170 reference measurement procedures for 79 analytes and 130 reference measurement services for 39 analytes. There remains a need for the development and implementation of metrological traceability in many areas of laboratory medicine and the JCTLM will continue to promote these activities into the future.
