Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15193 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 140, In vitro diagnostic medical devices, in collaboration with Technical Committee ISO/TC 212,
Clinical laboratory testing and in vitro diagnostic test systems, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).

Introduction
Reference measurement systems are needed to produce useful and reliable measurement results, whether in
science, technology 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 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 quantity,
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 vitally 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 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 standard are listed in ISO/IEC Guide 15.
In Clause 3 of this International Standard, concepts are indicated by italicized text.

INTERNATIONAL STANDARD ISO 15193:2009(E)

In vitro diagnostic medical devices — Measurement of
quantities in samples of biological origin — Requirements for
content and presentation of reference measurement procedures
1 Scope
This International Standard specifies requirements for the content of a reference measurement procedure for
in vitro 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 the 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 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 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 documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC Guide 99 and
ISO/IEC Guide 98-3 and the following apply.
3.1
primary sample
collection of one or more parts initially taken from a system and intended to provide information about the
system, or to serve as a basis for a decision about the system
NOTE In some cases, the information provided also applies to a larger system or a set of systems, of which the
sampled system is an element.
3.2
laboratory sample
primary sample, or 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 analytical 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 preparation 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 reaction
3.6
matrix
〈material system〉 components of a material system, except the analyte
3.7
reference measurement procedure
measurement procedure accepted as providing measurement results fit for their use in assessing
measurement trueness of measured quantity values obtained from other measurement procedures for
quantities of the same kind, in calibration, or in characterizing reference materials
NOTE 1 Adapted from ISO/IEC Guide 99:2007, 2.7.
NOTE 2 The roles of reference measurement procedures are detailed in ISO 17511 and ISO 18153.
NOTE 3 In ISO terminology, trueness is related to bias, systematic effect and systematic error, whereas accuracy is
related to both trueness (with its relations) and precision, which itself is related to standard deviation, random effect and
random error.
NOTE 4 The term “reference measurement procedure” is intended to be understood as a measurement procedure of
higher order.

3.8
analytical sensitivity
quotient of the change in an indication and the corresponding change in the value of a quantity being
measured
NOTE 1 The term “analytical sensitivity” is not intended to be used as a synonym for “detection limit”.
NOTE 2 ISO/IEC Guide 99:2007 uses the term “sensitivity of a measuring system”.
3.9
analytical specificity
ability of a measurement procedure to determine solely the quantity it purports to measure
3.10
analytical interference
systematic effect on a measurement caused by an influence quantity which does not by itself produce an
indication, but which causes an enhancement or depression of the indication
3.11
influence quantity
quantity that, in a direct measurement, does not affect a quantity that is actually measured, but affects the
relation between the indication and the measurement result
NOTE Adapted from ISO/IEC Guide 99:2007, 2.52.
3.12
measurand
quantity intended to be measured
NOTE 1 Adapted from ISO/IEC Guide 99:2007, 2.3.
NOTE 2 The term “analyte” is not intended to be used for measurand. Analyte is a component of a measurand.
EXAMPLE In the designation “Blood—Glucose; amount-of-substance concentration”, the term “Glucose” designates
the analyte, equal to the component.
3.13
detection limit
limit of detection
measured quantity value, obtained by a given measurement procedure, for which the probability of falsely
claiming the absence of a component in a material is β, given a probability α of falsely claiming its presence
NOTE 1 IUPAC recommends default values for α and β equal to 0,05.
NOTE 2 The abbreviation LOD is sometimes used.
NOTE 3 The term “sensitivity” is discouraged for this concept.
NOTE 4 Adapted from ISO/IEC Guide 99:2007, 4.18.
3.14
calibrator
measurement standard used in calibration
NOTE Adapted from ISO/IEC Guide 99:2007, 5.12.
