IUPAC Projects

Properties and Units for Transfusion Medicine and Immunohaematology

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 C-NPU (Committee on Nomenclature, Properties and Units)–maintained as a joint activity of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) and IUPAC–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 international system of units, concepts theory, and high-level international standards, is the main outcome and should be the cornerstone for expressing measurements within international communication standards. Thus, the task in this project is to work out properties and units for transfusion medicine and tissue typing based on the former CNPU concepts and syntactic rules.

It is a characteristic of the fields of transfusion medicine and tissue typing that the properties examined may involve both nominal, ordinal, 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 will be sought.
