Colloidal gold immunochromatography reader
1 Scope
This standard specifies the requirements, test methods, labels and instructions for use, packaging, transportation and storage of colloidal gold
immunochromatography analyzers.
This standard is applicable to instruments that interpret the results of samples by measuring the reflectivity of the bands in the reaction zone of the colloidal gold reagent card (hereinafter referred to as analyzers).
This standard does not apply to instruments that use fluorescent labels or other labeling methods for rapid immunoassay.

GB/T 29791.3 In vitro diagnostic medical devices - Information supplied by 3.4 Repeatability
It may choose one of the following methods:
a) Test quality control strips: Test three quality control strips with high, medium and low reflectivity in the range of [0.20, 0.80], respectively; the coefficient of variation (CV) shall not be greater than 3%.
b) Use of matching reagent test sample: Test samples with high, medium and low concentrations in the linear range, the coefficient of variation (CV) shall not be greater than 20%.
3.5 Linearity
It may choose one of the following methods:
a) Test quality control strip: Within the linear range of reflectivity [0.20, 0.80], the linear correlation coefficient (r) shall not be less than 0.990.
b) Use of matching reagent test sample: Within the linear range declared by the manufacturer, the linear correlation coefficient (r) shall not be less than 0.950.
3.6 Channel consistency (if applicable)
Test the quality control strip, the relative range (Rp) of the measurement results of each channel shall not be greater than 5%.
3.7 Stability
Test the quality control strip, the relative range (R) shall not exceed 5%. 3.8 Function
At least the following functions shall be included; the enterprise shall also determine other functions according to the characteristics of the product: a) Self-check function;
b) Function of input calibration information;
c) Function of result storage and query;
d) Fault prompt function.
3.9 Safety requirements
It shall meet the requirements of applicable clauses in GB 4793.1, GB 4793.9, YY 0648.
A2 - The reflectivity of quality control strip 2;
S2 - The response value of quality control strip 2.
4.3.2 Use of matching reagent test sample
Test a pair of samples which has a concentration difference not greater than 15% at the medical decision level (i.e., ); repeat the
measurement 10 times; if each measurement meets S1 - S2 < 0, then it meets the requirements of 3.2b).
Where:
X1 - The concentration of sample 1;
S1 - The measurement result of sample 1;
X2 - Sample with medical decision level concentration;
S2 - The measurement result of sample 2.
4.4 Accuracy
4.4.1 Relative deviation
Use matching reagents to test certified reference materials. The measured value is recorded as (Xi). Use the formula (1) to respectively calculate the relative deviation B. If the three measurement results meet the requirements of 3.3a), it is deemed qualified. If more than or equal to 2 measurement results do not meet, it is judged as unqualified. If one measurement does not meet the requirements, it shall make 20 tests continuously again; use the formula (1) to calculate the relative deviation. If greater than or equal to 19 measurement results meet the requirements of 3.3a), it is judged as qualified.
Where:
Xi - Each measured value;
T - The labeled value of the reference material.
4.4.2 Comparison test
Use matching reagents; refer to the method of CLSI EP09-A2; use no less than 40 clinical samples with different concentrations within the measurement d) The name, residence, production address, contact information and
production license number of the production enterprise. In case of
entrusted production, the name, residence, production address,
production license number of the entrusted enterprise shall also be

f) Power connection conditions and input power;
g) Graphics, symbols and other related content that shall be marked
according to product characteristics;
h) Necessary warnings and precautions;
i) Special storage, operating conditions or instructions.
Note: If it is not possible to indicate all the above content due to location or size limitation, at least the product name, model, specification, production date and expiration date shall be indicated, meanwhile the label shall clearly indicate that "see the instruction manual for other contents".
5.3 Instruction manual
The instruction manual shall meet the requirements of the Provisions on the Administration of Medical Device Instructions and Labels; it shall at least include the following:
