32、y or routine service, so as to be comparable and ultimately metrologically traceable to measurement units and/or measurement standards and/or measurement procedures of the highest metrological level. Reference measurement procedures play a crucial role in this metrological system because they can be
33、 used for the following: a) in assessing performance properties of measuring systems comprising measuring instruments, auxiliary equipment as well as reagents, b) in demonstrating if there is a functional interchangeability of different routine measurement procedures purporting to measure the same q
34、uantity, c) in assigning quantity values to reference materials that are then used for purposes of calibration or trueness control of routine measurement procedures, and d) in detecting analytical influence quantities in patient samples. For medical laboratory measurements, in particular, it is vita
35、lly important to both patient care and health screening that the measurement results reported to the physicians and patients are adequately comparable, reproducible and accurate. In some cases, it is advisable that a reference measurement procedure be given in the form of a standard, namely when it
36、is related to technical requirements: that are specified in standards, technical specifications, or technical regulations, etc., for which quantity values are to be stated by the supplier, and that have a direct relationship to the performance of a product or process. The advantages of having such a
37、 standard are listed in ISO/IEC Guide 15. In Clause 3 of this International Standard, concepts are indicated by italicized text. 4 EN ISO 15193:2009 (E) DIN EN ISO 15193:2009-10 1 Scope This International Standard specifies requirements for the content of a reference measurement procedure for in vit
38、ro diagnostic medical devices and medical laboratories. NOTE 1 It is intended that an experienced laboratory worker who follows a measurement procedure written in accordance with this International Standard can be expected to produce measurement results with a measurement uncertainty not exceeding t
39、he stipulated interval. This International Standard applies to reference measurement procedures providing values of differential or rational quantities. Annex A provides information on nominal properties and ordinal quantities. This International Standard is valid for any person, body or institution
40、 involved in one of the various branches of laboratory medicine whose intention is to write a document to serve as a reference measurement procedure. Full descriptions of measurement methods are usually published in scientific literature, in which methods are described in sufficient detail that they
41、 can be used as the basis of a documented measurement procedure. NOTE 2 In this International Standard, “international measurement standard” designates a material standard. The term “international standard” is used by WHO for reference materials. 2 Normative references The following referenced docum
42、ents are indispensable for the application of this document. For dated references, only the edition cited applies.

46、r a subsample of it, as prepared for sending to or as received by the laboratory and intended for measurement 3.3 analytical sample sample prepared from the laboratory sample and from which analytical portions can be taken NOTE The analytical sample can be subjected to various treatments before an a
47、nalytical portion is taken. 3.4 analytical portion portion of material taken from the analytical sample and on which the measurement is actually carried out, either directly or following dissolution NOTE The analytical portion is taken directly from the primary sample or laboratory sample if no prep
48、aration of these is required. The analytical portion is sometimes dissolved to give an analytical solution before being exposed to the measuring device. 3.5 analytical solution solution prepared prior to measurement by dissolving an analytical portion in a liquid or solid material, with or without r
