Completion Date: 2004 - project completed
Objective:
To work out properties and units for Transfusion Medicine and
Tissue Typing based on the former C-NPU commission's concepts and
syntactic rules. The C-NPU commission, maintained as a joint IFCC-IUPAC
activity for two decades, has as its main task to promote and maintain
scientifically and conceptually sound ways of expressing the outcome
of measurements and other examinations in laboratory medicine. The
NPU coding scheme and vocabulary, based on the SI system, concepts
theory and high-level international standards, is the main outcome
and should be the cornerstone for expressing measurements within international
communication standards.

Description:
The background, previous recommendations, and technical reports
are accessible from the link above.
It is a characteristic of the fields of Transfusion medicine and tissue
typing that the properties examined may involve both nominal, ordinal
("titre"), differential, and rational scales. Thus the project will
establish the metrological and logical basis for expressing such properties.
In addition, the necessary international coding scheme identifiers
and code values will have to be chosen as required by interlaboratory
transmission between databases. In this respect, active collaboration
and/or endorsement by the International Society of Blood Transfusion
and its working parties on the terminology for red cells, platelet
and neutrophile antigens will be sought. Unambiguous expression of
properties will assist in fulfilling safety and legal requirements
in the handling of blood products intended for transfusion and organs
intended for transplantation. The project conforms to the IUPAC strategic
goals 2 and 4 i.e. to promote standardized nomenclature, symbols,
terminology and methodology in the chemical sciences as well as to
facilitate the development of effective channels of communication
in international chemistry community.
