Ta mednarodni standard določa zahteve za sisteme nadzora glukoze v krvi in vitro, ki merijo koncentracije glukoze v vzorcih kapilarne krvi, za posebne postopke overjanja modelov in za preverjanje delovanja s strani predvidenih uporabnikov. Ti sistemi so namenjeni za samopreskušanje pri obravnavi sladkorne bolezni, torej za laično uporabo. Ta mednarodni standard velja za proizvajalce takšnih sistemov in druge organizacije (npr. regulativni organi in organi za ugotavljanje skladnosti), odgovorne za ocenjevanje delovanja takšnih sistemov. Ta mednarodni standard: – ne zagotavlja celovitega vrednotenja morebitnih dejavnikov, ki bi lahko vplivali na delovanje teh sistemov; – ne zadeva merjenja koncentracije glukoze z namenom diagnosticiranja sladkorne bolezni; – ne obravnava zdravstvenih vidikov obravnave sladkorne bolezni; – ne velja za postopke merjenja z izmerjenimi vrednostmi po razvrstitveni lestvici (npr. vizualni polkvantitativni postopki merjenja) ali za sisteme neprekinjenega nadzora glukoze; – ne velja za merilnike glukoze, ki so namenjeni za uporabo v medicini za nadzor sladkorne bolezni, ki ga ne izvaja oboleli sam.

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 15197 was prepared by Technical Committee ISO/TC 212, Clinical laboratory testing and in vitro

diagnostic test systems.

This second edition cancels and replaces the first edition (ISO 15197:2003), the clauses, subclauses and

annexes of which have been technically revised.

Introduction

Blood-glucose monitoring systems are in vitro diagnostic medical devices used predominantly by

individuals affected by diabetes mellitus. Diabetes mellitus is caused by a deficiency in insulin secretion

or by insulin resistance leading to abnormally high concentrations of glucose in the blood, which may

result in acute and chronic health complications. When used properly, a glucose monitoring system

allows the user to monitor and take action to control the concentration of glucose present in the blood.

This International Standard is intended for blood-glucose monitoring systems used by lay persons. The

primary objectives are to establish requirements that result in acceptable performance and to specify

procedures for demonstrating conformance to this International Standard.

Minimum performance criteria for blood-glucose monitoring systems were established from the

analytical requirements (precision and trueness) for individual glucose measurement results. “System

accuracy” is the term used in this International Standard to communicate the analytical capability of

a blood-glucose monitoring system to the intended users (i.e. lay persons), who would not be familiar

with metrological terms commonly used in laboratory medicine. System accuracy describes the ability

of a glucose monitoring system to produce measurement results that agree with true glucose values

when the system is used as intended. The concept of “system accuracy” includes measurement bias and

measurement precision.
The requirements for system accuracy are based on three considerations:

— the effectiveness of current technology for monitoring patients with diabetes mellitus;

— recommendations of diabetes researchers as well as existing product standards and regulatory

guidelines; and
— the state-of-the-art of blood-glucose monitoring technology.

In arriving at the performance requirements specified in the second edition of this International

Standard, desirable goals had to be weighed against the capabilities of existing blood-glucose

monitoring technology. The revised performance criteria in this edition are the result of improvements

in technology since publication of the first edition. The considerations that formed the basis for the

minimum acceptable analytical performance of a blood-glucose measuring device intended for self-

monitoring are described in Annex C.

Requirements that are unique to self-monitoring devices for blood-glucose are addressed in this

International Standard. Requirements that apply in general to all in vitro diagnostic medical devices are

incorporated by reference to other standards where appropriate.

Although this International Standard does not apply to glucose monitoring systems that provide

measured values on an ordinal scale (e.g. visual, semiquantitative measurement procedures) or medical

devices that measure blood-glucose continuously for self-monitoring, it may be useful as a guide for

developing procedures to evaluate the performance of such systems.

INTERNATIONAL STANDARD ISO 15197:2013(E)
In vitro diagnostic test systems — Requirements for blood-

diabetes mellitus
1 Scope

This International Standard specifies requirements for in vitro glucose monitoring systems that measure

glucose concentrations in capillary blood samples, for specific design verification procedures and for

the validation of performance by the intended users. These systems are intended for self-measurement

by lay persons for management of diabetes mellitus.

This International Standard is applicable to manufacturers of such systems and those other organizations

(e.g. regulatory authorities and conformity assessment bodies) having the responsibility for assessing

the performance of these systems.
This International Standard does not:

— provide a comprehensive evaluation of all possible factors that could affect the performance of

these systems,

— pertain to glucose concentration measurement for the purpose of diagnosing diabetes mellitus,

— address the medical aspects of diabetes mellitus management,

— apply to measurement procedures with measured values on an ordinal scale (e.g. visual,

semiquantitative measurement procedures), or to continuous glucose monitoring systems,

— apply to glucose meters intended for use in medical applications other than self-testing for the

management of diabetes mellitus

glucose concentrations in blood

Note 1 to entry: Blood-glucose monitoring systems measure glucose in capillary blood samples, but can express

measured values as either the glucose concentration in capillary blood or the equivalent glucose concentration

in capillary plasma. Concentrations in this International Standard refer to the type of measured values reported

by the system.
3.2
blood-glucose meter

component of a blood-glucose monitoring system that converts the product of a chemical reaction into

the glucose concentration of the sample
3.3
capillary blood-sample
blood sample collected by skin puncture

Note 1 to entry: A finger punctured by a lancet is commonly called a “fingerstick”.

3.4
commutability of a reference material

property of a reference material, demonstrated by the closeness of agreement between the relation among

the measurement results for a stated quantity in this material, obtained according to two given measurement

procedures, and the relation obtained among the measurement results for other specified materials

Note 1 to entry: The reference material in question is usually a calibrator and the other specified materials are

usually routine samples.

Note 2 to entry: The measurement procedures referred to in the definition are the one preceding and the one following

the reference material (calibrator) in question in a calibration hierarchy. See ISO 17511 for further information.

Note 3 to entry: The stability of commutable reference materials is monitored regularly.

[ISO/IEC Guide 99:2007, definition 5.15]

Note 4 to entry: Although blood would be the ideal matrix for reference materials for blood-glucose monitoring

devices, such materials are not available at this time.
