Foreword
GB/T 19634 “In vitro diagnostic test systems - General technical requirements for
blood-glucose monitoring systems for self-testing” is not equivalent to ISO 15197.
This Standard was proposed by China Food and Drug Administration.
This Standard shall be under the jurisdiction of the National Clinical Trial Laboratory
and in-Vitro Diagnostic System Standardization Technical Committee.
Drafting organizations of this Standard. Beijing Institute of Medical Device Testing, and
American Johnson & Johnson Ltd.
Main drafters of this Standard. Hu Dongmei, Xu Yong, and John Mahoney.
Introduction 
Blood-glucose monitoring systems for self-testing are in vitro diagnostic medical
devices used mainly by lay persons. When used properly, they can help diabetics to
monitor and take action to control the glucose concentration in the blood.
The primary objectives of this Standard are to establish requirements for the design of
blood-glucose monitoring systems that can result in acceptable results when used by
lay persons on the premises that users have accepted certain training, devices have
been properly maintained and operated according to the calibration and quality control
procedures in instructions for use of manufacturers, and to specify procedures for
verifying the conformance of blood-glucose monitoring systems’ indicators to this
Standard.
This Standard illustrates general technical requirements for blood-glucose monitoring
systems for self-testing, including the information provided by the manufacturer and
labels and instructions of blood-glucose monitoring systems for self-testing. Since the
self-testing systems are used by lay persons, the information provided by the
manufacturer shall be explicit and easily to be understood, for the convenience of users
to have self-testing according to the operation procedures correctly. At the same time,
it shall provide certain warnings or prompts, to guide the appropriate measures under
abnormal results. This Standard specifies the information provided by the
manufacturer in detail.
In vitro diagnostic test systems - General technical
requirements for blood-glucose monitoring systems for
self-testing
1 Scope 
This Standard specifies the terms and definitions, requirements, test methods, labels
and instructions for use, packaging, transportation, and storage for blood-glucose
monitoring systems for self-testing.
This Standard is applicable to the blood-glucose monitoring systems for self-testing
intended for in vitro monitoring the glucose concentration in capillary whole blood
and/or venous whole blood (normally including portable glucose meters, disposable
test strips, and control materials).
2 Normative references 
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For dated references, the subsequent amendments
(excluding corrigendum) or revisions do not apply to this Standard, however, parties
who reach an agreement based on this Standard are encouraged to study if the latest
versions of these documents are applicable. For undated references, the latest edition
of the referenced document applies.
GB 4793.1-1995 Safety requirements for electrical equipment for measurement,
control and laboratory use – Part 1. General requirements (idt IEC1010-1.1990)
GB 9706.1-1995 Medical electrical equipment – Part 1. General requirements for
safety (idt IEC 601-1.1988)

3 Terms and definitions 
The following terms and definitions apply to this Standard.
[ISO 3534-1.1993, Definition 3.14]
Note 1. The precision degree is expressed in numerical form of the measurement imprecision obtained
by statistical measures, such as standard deviation (SD) and coefficient of variation (CV), that shows
a negative correlation with precision. Quantitative measures of precision depend on the specified
conditions.
Note 2. Precision of a given measurement procedure can be classified according to the clear precision
conditions. Precision under specific conditions are termed as “repeatability” and “reproducibility”.
3.5
Repeatability
Consistency between test results obtained with continuous multiple measurements
under the same measurement conditions.
[JJF 1001-1998, Definition 5.6]
3.6
Repeatability conditions
Conditions where independent test results are obtained with the same test method, on
same test object, in the same laboratory, by the same operator, using the same
equipment, and within short intervals of time.
[ISO 3534-1.1993, Definition 3.16]
Note. Essentially constant conditions, intended to represent conditions resulting in test results of
minimum variability.
3.7
Blood-glucose meter
Component of a blood-glucose monitoring system, it can convert the result of a
chemical reaction into the glucose concentration in the sample.
3.8
Label
Printed, written or graphic information placed on a device or container.
3.9
Instructions for use
(> 75 mg/dL)
4.4 Batch-batch difference of blood-glucose test strips
Batch-batch difference between different batches of blood-glucose test strips shall not
be greater than 15%.
4.5 Control material
95% of test result obtained with control material shall be within the quality control range
of blood-glucose test strips.
4.6 Environmental test for blood-glucose meter
It shall meet the requirements of applicable articles in GB/T 14710-1993.
4.7 Safety requirements for blood-glucose meter
It shall meet the requirements of applicable articles in GB 9706.1-1995 and/or GB
4793.1-1995.
5 Test method 
5.1 Test materials
a) Blood-glucose meter (at least 2 blood-glucose meters of the same specification
are recommended);
b) Blood-glucose test strips;
c) Reference analysis meter in accordance with manufacturer’s suggestions;
d) Blood-glucose reference materials with traceability (such as the reference
material SRM 965 of National Institute of Standards and Technology (NIST));
e) Venous blood-sample or capillary blood-sample;
f) Blood collection tube added with proper anticoagulant;
g) Low speed centrifuge;
h) Straw;
i) Colorimetric tube or small test tube used for reference analysis meter;
j) Instructions for use of calibration and control procedures provided by the
manufacturer;
Note 1. In some cases, to promise the completion of measurement, a second skin puncture may be
necessary.
Note 2. It can adjust glucose concentrations in capillary blood-samples according to the method in
5.5.1a), to obtain samples in the lowest and highest concentration ranges.
5.4.2.2 Test procedure
DIVIDE capillary blood-sample into two aliquots firstly. PERFORM glucose
concentration test on one portion by reference analysis meter according to the
standard measurement procedure of manufacturer. TEST another portion by two
glucose meters according to the method in the instructions for use of manufacturer.
If reference analysis meter is only designed for testing plasma samples, then add an
anticoagulant recommended by the manufacturer into one portion, and collect plasma
by centrifugation at 1000g for 10 min. PERFORM the glucose measurement according
to the standard measurement procedure of manufacturer.
The differences between results of blood/plasma from each blood-glucose meter and
the results of blood/plasma from reference analysis meters are deemed as the
deviation.
5.5 Batch-batch difference of blood-glucose test strips
USE blood-glucose test strips of 2 different batches to repeatedly measure the fresh
anticoagulant venous blood or control material of normal fasting people for 10 times
respectively on a same blood-glucose meter. CALCULATE mean value of test results
of 2 batches respectively, and calculate the total mean value of test results of 3 batches.
CALCULATE batch-batch difference according t...
