Abstract The terminology of NPU (nomenclature for properties and units) aims at describing properties examined in clinical laboratories for a patient. It was originally jointly approved in 1966 by IUPAC and by the International Federation of Clinical Chemistry (IFCC) and covers multiple disciplines in the field of clinical laboratory sciences, including clinical allergology, clinical chemistry, clinical haematology, clinical immunology and blood banking, clinical microbiology, clinical pharmacology, molecular biology and genetics, reproduction and fertility, thrombosis and haemostasis, and toxicology. The NPU terminology adheres to international standards of metrology and of terminology, in particular the International System of Quantities (ISQ) and International System of Units (SI), the International Vocabulary of Metrology (VIM), and also to ‘An outline for a vocabulary of nominal properties and examinations – basic and general concepts and associated terms,’ recently prepared on behalf of the IFCC-IUPAC Committee-Subcommittee on Nomenclature for Properties and Units. The present document recalls the definitions of the concepts used to express a property of a patient, regarded as a system. The aim is to promote by this comprehensive summary the proper NPU terminology for reliable exchange of patient examination data. The use of this syntax and of SI units enables the translation of these descriptions into other languages without loss of meaning or accuracy. The NPU format is also well adapted for comparative and epidemiological studies. More information will be found in the upcoming 2nd edition of the Compendium of Terminology and Nomenclature of Properties in Clinical Laboratory Sciences, the IUPAC and IFCC ‘Silver Book’, and in the recently published ‘Properties and units in the clinical laboratory sciences. Part XXIII. The NPU terminology, principles, and implementation: A user’s guide (IUPAC Technical Report)’ (DOI:10.1351/PAC-REP-11-05-03).

This document is part of an ongoing effort to standardize transmission of laboratory data across cultural and linguistic domains, without attempting to standardize the routine language used by clinicians and laboratory practitioners. It comprises a general introduction and an alphabetic list of properties. The list is based on the syntax for properties recommended by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) and the International Union of Pure and Applied Chemistry (IUPAC). The nomenclature is primarily from the Working Party on Terminology of the International Society of Blood Transfusion (ISBT).

Synopsis: A coding scheme has been prepared for general clinical chemistry.PrefaceThe present document is part ten (X) of a series on properties and units in the clinical laboratory sciences initiated in 1987. > View series titles (view corresponding project) The size and complexity of parts III and IV are such that their lists will be presented in electronic format. This is for ease of handling and to facilitate expression of concepts in different languages. At the end, systematic terms, elaborated according to international standards and recommendations should be available in the different domains of clinical laboratory sciences. The core of the series is code value strings representing concepts, that in combination delineate and define each type of property regardless of linguistic expression, thus avoiding errors during translation between languages. Foreword and ScopeClinical Laboratory Sciences are characterised by the exacting nature of the work performed and the demand for an accurate presentation of the outcome. Further the domain is transnational, international or "global". The adherent informatics system therefore needs to identify the findings accurately and to present them with the degree of detail required. At the same time it has to facilitate the transfer over linguistic and cultural barriers without distortion or loss of clarity, in order to promote clear, unambiguous, meaningful and fully informative communication in different terminologies. The degree to which a message (such as a laboratory report) needs to be expressed in a formal, systematic language depends on the geographical, linguistic, social or professional distance between the communicating parties. The greater the distance, the greater the risk of misunderstanding. Within one laboratory, local jargon terms may be used which are usually well understood between colleagues, but which would not be sufficiently widely known for communication with the outside world. Likewise, a laboratory and its local community of users, such as hospital or community physicians, may use a "local dialect" of the language of laboratory medicine which is well understood by all concerned; but when the communication possibilities are wider, even transnational, risks of serious misunderstanding arise.The purpose of this document is to apply the IFCC-IUPAC recommended syntax structures for request and report and to create a systematic terminology which can be used as the basis for encoding laboratory messages in the domain of general clinical chemistry. This is to facilitate communication of messages about such properties through computing and telecommunication between databases, messages that contain sufficient information to allow translation from and to the required "local dialect" at each end. Each entry in the list is formed following the rules given in part I and part XI of the series. The systematic names recommended here are primarily for the purpose of unambiguous data exchange. Their use in routine language by clinician or laboratory practitioners is optional but encouraged.

The purpose of this paper is introducing research conducted about issues related to influences and barriers to the potential use of distance education for mitigating the clinical laboratory sciences labor shortage. Diagnostic careers such as those in the clinical laboratory sciences remain a mystery to many people because they do not have the same prominence or visibility associated with therapeutic careers. Clinical laboratory science courses often have both didactic and laboratory components. Coursework with laboratory components require additional faculty time for preparation. When health care education is offered in traditional university or college settings not affiliated with a teaching hospital or clinical setting, laboratory costs are higher due to purchasing supplies, reagents and media. Issues are further explored in a brief series of papers addressing them.  Using DE for delivering diagnostic clinical educational is a potential viable solution for addressing national diagnostic labor shortages.

Abstract Spaceborne measurements pinned to international standards are needed to monitor the earth’s climate, quantify human influence thereon, and test forecasts of future climate change. The International System of Units (SI, from the French for Système International d’Unités) provides ideal measurement standards for radiometry as they can be realized anywhere, at any time in the future. The challenge is to credibly prove on-orbit accuracy at a claimed level against these international standards. The most accurate measurements of thermal infrared spectra are achieved with blackbody-based calibration. Thus, SI-traceability is obtained through the kelvin scale, making thermometry the foundation for on-orbit SI-traceable spectral infrared measurements. Thermodynamic phase transitions are well established as reproducible temperature standards and form the basis of the international practical temperature scale (International Temperature Scale of 1990, ITS-90). Appropriate phase transitions are known in the temperature range relevant to thermal infrared earth observation (190–330 K) that can be packaged such that they are chemically stable over the lifetime of a space mission, providing robust and traceable temperature calibrations. A prototype blackbody is presented that is compact, highly emissive, thermally stable and homogeneous, and incorporates a small gallium melting point cell. Precision thermal control of the blackbody allows the phase transition to be identified to within 5 mK. Based on these results, the viability of end-to-end thermometric calibration of both single-temperature and variable-temperature blackbodies on orbit by employing multiple-phase-change cells was demonstrated.
