Coding
scheme for clinical laboratories
Since 1995, the Commission of Nomenclature, Properties and Units
(C-NPU of IUPAC and IFCC) has published nine papers on a coding
system (i.e. a structure or a frame for the pairs of codes and
meaning) and a coding scheme (i.e. the pairs of codes and their
meaning), for clinical laboratories. �Meanings� can be descriptions
of quantities which are measured or observed in laboratory
medicine. A further four papers are now added with codes in the
domains of Allergology, Microbiology, Pharmacology and Clinical
chemistry. The codes offer a unique and sufficient information
about the quantities and is therefore extremely valuable in the
transfer of information between laboratories and to the end users
of laboratory information. The codes make it possible to
automatically translate the data to any language. So far the
meanings have been translated into 18 languages, including many of
the European languages, Arabic and Cantonese.
The coding scheme thus comprises a total of 10083 pairs with the
international coding scheme identifier "NPU" for properties, and a
further 13379 pairs for elements. These latter ones are for use
primarily as results of taxonomic investigations; example:
NPU16294
Secr(Orophar)�Bacterium+fungus; taxon = ATCC12600(Staphylococcus
aureus).ATCC12344(Streptococcus pyogenes).
NPU04062 U�Benzodiazepines; taxon = CAS846-49-1(Lorazepam);
CAS439-14-5(Diazepam)
In order to test the functionality, the coding scheme has been
succesfully mapped to the various codes which are presently used in
45 different clinical laboratories in Denmark. To accommodate local
needs some new codes identified by �DNK� have been added.
The domains presently covered by the IUPAC/IFCC coding scheme are
Allergology, Clinical Chemistry, IOC prohibited Drugs,
Microbiology, Pharmacology, Reproduction and Fertility, Thromboses
and Haemostasis, Trace Elements. The schemes have been prepared in
collaboration with professional groups and organisatons which
represent the various specialities.
To be prepared are coding schemes for Molecular Biology, Blood
banking, Tissue Typing, Inborn Errors, Tumor Markers.
The coding scheme is accessible on www.ifcc-iupac.suite.dk.
