Nomenclature, Properties and Units (C-NPU) in collaboration with International Union of Pure and Applied Chemistry (IUPAC)
The IFCC-IUPAC coding system
Provides a terminology for Properties and Units in the Clinical Laboratory Sciences. The availability of electronic patient records would greatly increase the quality of health care, reduce health care cost and facilitate epidemiological surveys to the benefit of patient's worldwide. In developing a generalized architectural build up and adherent structures, there is a need for systems and schemes in each of the medical domains to support and populate the electronic patient record. In the domain of clinical laboratory medicine the guidelines from IFCC-IUPAC on the structuring of properties, on kind-of-properties and on units are needed if a coherent system with global acceptance is to be worked out.
The C-NPU maintains the website below to make available the complete contents of the generic C-NPU database for electronic downloading. The website outlines the structure of the NPU terminology and provides instructions for using the database. NPU Laboratory Terminology website: www.npu-terminology.org
A current version of the C-NPU database (in English) is also available for direct download

IFCC-IUPAC / C-NPU documents
The background for the IFCC-IUPAC coding system for laboratory investigations is described in the publications.
Also a series of documents from the Word Health Organization, from the European Standardization Committee and many international organizations have been adhered to in the course of the project, in particular for coding of concepts defined by these organizations e.g. CAS, ATCC, UMLS, CLSI, UMD, INN, ISTH, OMIM.

Terms of Reference
- To continuously provide advice in relation to the management, updating and publishing of NPU terminology.
- To make recommendations on NPU for reporting clinical laboratory data that conform to or adapt current standards of authoritative organizations, and that will improve their utilization for health care.
- To provide a connection with other organizations concerned with NPU, such as the Bureau International des Poids et Mesures (BIPM), the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO), and, by extension, clinical laboratory sciences societies, such as the International Union of Pure and Applied Chemistry (IUPAC), and the in vitro diagnostics industry, to ensure that problems encountered by health care professionals in the area of NPU are considered by those organizations.
- To act as a consultant group on NPU in clinical chemistry and, by extension, in the rest of clinical laboratory sciences to international scientific panels, regional and national clinical laboratory sciences organizations, editors of scientific journals, manufacturers of clinical laboratory instrumentation and products, and to individual clinical laboratory professionals and other health care professionals.
- To report and offer advice to the SD Chair and the SD Executive Committee on matters concerning NPU in all its aspects (all items above).
- Transfer of the NPU generic database to IFCC site : help and advice on training the future IFCC NPU database manager(s) in relation to the installation, updating and management of the database, and on its relationship relations with other national versions.
- Mapping of the IFCC-IUPAC laboratory coding system to SNOMED CT.
- Securing and structural updating of information in the NPU coding system and its environment.
- Development of an international vocabulary for nominal examinations in scientific communication.
