This section provides information on the status of harmonization or standardization of measurands. Priorities based on medical impact are provided for measurands for which harmonization is needed or that have an incomplete or inactive implementation of a harmonization activity. Additional information regarding the harmonization status and medical impact is available by clicking on the measurand name. Information on reference materials, reference measurement procedures, and reference laboratory services is provided by the links in the JCTLM column. Links to organizations actively addressing harmonization of particular measurands are provided for additional information on those projects.
Summary of Measurand Harmonization Activities
The measurand table is a dynamic information resource. Check regularly for new information.
Click on a measurand to see additional information regarding harmonization status and medical impact.
Click on a JCTLM component or an organization link for information on those resources.
Click on a single column to sort the table.
1 Low, medium and high refer to the medical impact of the current inadequate harmonization on potential medical errors in interpreting a result for a measurand.
2 Harmonization status: Active means an organization is implementing a harmonization project; Adequate means the current harmonization is suitable for medical decisions; Inactive means a harmonization activity was started but is no longer being actively implemented; Incomplete means resources to achieve harmonization are available but have not been adequately implemented; Needed means no harmonization activity has been started but one is needed.
3 JCTLM abbreviations: RM, reference material; RMP, reference measurement procedure; RL, reference laboratory.
