Testing).
2 Normative References
The following documents are indispensable to the application of this document. In
terms of references with a specified date, only versions with a specified date are
applicable to this document. In terms of references without a specified date, the latest
version (including all the modifications) is applicable to this document.
GB 3100 The International System of Units and Its Application
YY 0466-2003 Medical Devices - Symbols to be Used with Medical Device Labels,
Labelling and Information to be Supplied
YY/T 0638 In Vitro Diagnostic Medical Devices - Measurement of Quantities in
Biological Samples - Metrological Traceability of Assigned Values for Catalytic
Concentration of Enzymes in Calibrators and Control Materials
3 Terms and Definitions
The following terms and definitions are applicable to this Standard.
3.1 In Vitro Diagnostic Reagent
accompanied by the uncertainty of a given confidence level.
NOTE: since some reference materials and certified reference materials cannot be related
to a certain chemical structure, or, due to other reasons, their properties cannot be
determined in accordance with the strictly specified physical and chemical
measurement methods. This type of materials include certain biological materials,
and the World Health Organization has stipulated the corresponding international
units.
[JJF 1001-1998, Definition 8.14]
3.7 Repeatability
Repeatability refers to the consistency among the results obtained from multiple
consecutive measurements of the same measured object under the same
measurement conditions.
[JJF 1001-1998, Definition 5.6]
3.8 Precision of Measurement
Precision of measurement refers to the degree of consistency among mutually
independent measurement results under specified conditions.
NOTE 1: precision of measurement cannot be used to represent the digital value related
to the measurement and can only be described as “sufficient” or “insufficient” for
the specified purpose.
NOTE 2: the degree of precision is usually expressed by the statistics of measurement
imprecision that are opposite to precision, such as: standard deviation and
coefficient of variation.
NOTE 3: the “precision” of a given measurement procedure may be classified in
accordance with specific precision conditions. “Repeatability” is related to
basically unchanged conditions and is often known as “in-sequence precision”
or “within-run precision”. “Reproducibility” is related to condition changes, such
as: time, different laboratories, operators and measurement systems (including
different calibrations and reagent batch numbers).
[GB/T 21415-2008, Definition 3.23]
3.9 Repeatability Conditions
Repeatability conditions refer to the conditions, under which, mutually independent test
results are obtained from the same test object within a short period of time in the same
laboratory, by the same operator using the same instrument and through the same test
method.
Stability refers to the capability of the reagents (kits) to maintain the characteristics
within the limits specified by the manufacturer.
NOTE 1: stability is applicable to: when in vitro diagnostic reagents, calibrators or quality
control materials are stored, transported, and used under the conditions
specified by the manufacturer; freeze-dried materials and / or prepared working
solutions after redissolution; materials to open sealed containers; calibrated
instruments or measurement systems.
NOTE 2: the stability of in vitro diagnostic reagents or measurement systems is usually
quantified by time. Stability may be quantified by the time of a certain quantity of
changes in metrological performance characteristics or the quantity of changes
in characteristics within a certain period of time.
NOTE 3: ISO/FDIS 18113-1, Definition 3.68 is modified.
3.15 Label
Label is printed, written or graphic information on in vitro diagnostic medical devices or
their containers.
[ISO/FDIS 18113-1, Definition 3.33]
3.16 Instructions for Use
Instructions for use refer to information provided by the manufacturer on the safe and
correct use of the reagents (kits).
NOTE: ISO/FDIS 18113-1, Definition 3.30 is modified.
3.17 Immediate Container (primary container)
Immediate container (primary container) refers to packaging that prevents the contents
from being contaminated and other influences from the external environment.
Example: sealed bottles, ampoules or bottles, tin foil bags, sealed plastic bags.
[ISO/FDIS 18113-1, Definition 3.24]
3.18 Outer Container
Sales Packaging
Outer container / sales packaging refers to materials used for the packaging of the
immediate container (primary container) of the reagents (kits).
NOTE: ISO/FDIS 18113-1, Definition 3.49 is modified.
