Synopsis
To facilitate and to assure correct electronic transmission of request and report on clinical laboratory properties over cultural and linguistic barriers, a systematic nomenclature has been prepared for a series of laboratory specialities.
Each defined property has been given a unique code value preceded by the coding scheme identifier: NPU.
The NPU code value and its adhering code value string for each term allow expression of the concept according to local script, idiom or conventions.
The coding scheme is accessible on Internet from C-NPU Home page address http://www.ifcc-iupac.suite.dk

Scope
The coding scheme prepared is intended as a repository of code values and terms of properties to be used in the transfer of information on such properties through computing and telecommunication equipment used in the health services.

Preface
The document is the fourth part of a series on properties measured in the clinical laboratory sciences initiated in 1987.
The series will comprise the five general parts (I-IV and XI) and a series of special parts:
 
Syntax and semantic rules
II  Kinds-of-property
III  Elements (of properties) and their code values
IV  Properties and their code values (this document)
Properties and units in Thrombosis and Haemostasis
VI  Properties and units in IOC prohibited drugs
VII  Properties and units in Inborn Errors of Metabolism
VIII  Properties and units in Clinical Microbiology
IX  Properties and units in Trace Elements
Properties and units in General Clinical Chemistry
XI  Coding systems - structure and guidelines
XII  Properties and units in Clinical Pharmacology and Toxicology
XIII  Properties and units in Reproduction and Fertility
XIV Properties and units in Tumor Markers
XVI  Properties and units in Clinical Allergology

The size and complexity of part III and IV is such that their lists will be presented in electronic format only.
The overall aim is access by electronic media of:
"Compendium of terminology and nomenclature of properties in clinical laboratory sciences".
"Glossary of terms in quantities and units in clinical chemistry".
"Properties and units in the clinical laboratory sciences" (the present series of documents).

Introduction
The variety of properties observed in the domain of the Clinical Laboratory Sciences is well over 5000. The number of properties observed is 5 to 10 per inhabitant per year in industrialised countries.
An increasing part of the billions of requests and reports is transmitted by electronic means, mostly by code values from a local coding scheme.
The expression of the meaning of a code value is according to local habit, rules and conventions. This often is not readily transformed to coded sets from other coding schemes.
To facilitate inter region electronic communication, the European standard ENV 1614:1995 has presented a system of concepts based on for a systematic nomenclature to function as a bridge between local dialects.
 



Fig. 1. From ENV 1614:1995


 


Based on this system of concepts and on the European standard ENV 12435:1996, that deals with the presentation of results, terms have been elaborated and codified for communication between clinical laboratory information systems and other health information systems.
A basic document for further description and clarification is "Compendium of terminology and nomenclature of properties in the clinical laboratory sciences", while details of the syntax and semantic rules are given in Ref.1.

Systematic names and results
The outcome of a laboratory examination may be schematised as

Property = Result

or more specified

System(specification)--; kind-of-property(specification) = value · unit

or as generally in Clinical Laboratory Sciences

System(specification)-Component(specification); kind-of-property(specification) = value · unit

Although the system of concepts is generally applicable, modifications and extensions are needed in some subject fields.
For this reason, detailed coding schemes for some categories of properties have been worked out by authorities in that speciality for publication in separate documents. The present document is a compilation of terms from the different specialities.
Each term has been given a code value prefixed by the coding scheme identifier NPU (from Nomenclature, Properties and Units). The numeric value is a consecutive number with no meaning per se. It represents a code value string for that property; that is a series of values representing semantic links and a series representing values for elements from the coding scheme in part III (Elements (of properties) and their code values) (Table 1).
 
Table 1.  
Semantic link Element (example)
Code value Meaning

Now follows a code value of a:

Code value Meaning 
QU59901 System MSHD010949 Plasma
QU59902 Specification to a system    
QU59903 Component CAS50-99-7 Glucose
QU59904 Specification to a component    
QU59905 Kind-of-property QU50003 substance concentration
QU59906 Specification to a property    
QU59907 Numerical value = 5,6
QU59909 Unit QU09408 millimole/litre
QU59910 End code QU99999 End

or as a code value string:

[NPU02192] QU59901:MSHD010949:QU59903:CAS50-99-7:QU59905:QU50003:QU59907: = 5,6:QU59909:QU09408:QU59910:QU99999:

The coding scheme for properties basically comprises a list of coded sets that is an NPUXXXXX and a corresponding code value string (Sample page 1). On expressing the code values for elements in a particular language, the list of properties is generated in that language. The present list is presented in English (Sample pages 2 and 3).

Details are in part XI Coding systems - Structure and guidelines.

Each entry comprises a term with an NPU code value and when appropriate a molar mass, calibrator, authority, (when appropriate other terms and notes), and an example in a short form.

EXAMPLE

    Plasma-
Glucose;
    substance concentration
    millimole/litre
    M = 180,2 g/mol
    Authority: CAS50-99-7
    [NPU02192]
    P-Glucose; subst.c. = ? mmol/l

Functionality

Specialities
Testing and inclusion in the list has been done for clinical allergology, clinical bacteriology, clinical chemistry, clinical pharmacology, complement factors, haematology, clinical immunology, inborn errors of metabolism, reproduction and fertility, trace elements, and thrombosis and haemostasis.

The list is to be expanded as needs arise.

Linguistic expression
The basis of the coding scheme is the code value strings, representing the meaning of the NPU code values.

The expression has been successfully tested in:

  1. Germanic languages: English, German, Dutch, Norwegian, Swedish, Danish.
  2. Romance languages: French, Catalan, Italian, Spanish, Portuguese.
  3. Slavic languages: Czech, Slovak.
  4. Other languages: Arabic, Chinese, Finnish and Welsh.
EXAMPLE [NPU02192]

P-Glukos; subst konc = 5,6 mmol/L Swedish

Pla-Glucosa; c.sust. = 5,6 mmol/l Spanish

Internet access
The information on properties is given in three forms on the Home page:

  1. Code value strings preceded by an NPU code value as in Sample page 1. Each code value string represents the definition of a property (See sample pages 2 and 4).
  2. Short form comprising the abbreviated presentation of properties as in Sample page 4.
  3. Complete text as in Sample pages 2 and 3.
