3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Colloidal Gold Technology
A labeling technique that uses colloidal gold particles as a tracer or chromogenic substance for antigen-antibody reaction or other molecular detection.
3.2
Minimum detection limit
The lowest measured value in a sample that can be declared different from zero with a certain probability.
3.3
Analysis specificity
The measurement program only measures the ability to be measured.
3.4
Quality control
Substances, materials or articles used to verify the performance characteristics of in vitro diagnostic reagents (kits).
3.5
Repeatability
Under the same measurement conditions, the consistency between the results obtained by consecutive multiple measurements on the same measured.
4 requirements
4.1 Physical properties
4.1.1 Appearance
Meet the normal appearance requirements specified by the manufacturer.
4.1.2 Film strip width
Should not be less than 2.5mm.
4.1.3 Liquid moving speed
The liquid moving speed should not be less than 10mm/min.
4.2 Accuracy
Detect cTnI positive quality control products, the results should all be positive.
4.3 Repeatability
Take 10 test strips of the same batch number and test the cTnI positive quality control products of the same concentration. The reaction results should be consistent, the color development should be uniform, and the
Is positive.
4.4 Analysis specificity
Test the cTnI specific quality control material, the reaction result should be negative.
Note. cTnI specific quality control products are normal negative plasma or serum samples, quality control products of troponin T and quality control products of troponin C.
4.5 Minimum detection limit
The sensitivity of the cTnI quality control product should not be higher than 1.0ng/mL.
4.6 Stability
Take the test paper of the same batch number and place it at 37℃ for 20 days. The result should meet the requirements of 4.2~4.5.
5 Test method
5.1 Judgment basis for results (see Figure 1)
5.1.1 Positive. The color of the color band of the detection line (T) is the same as or deeper than the quality control line (C).
5.1.2 Negative. Only the quality control line (C) appears.
5.1.3 Invalid. No ribbon appears on the quality control line (C).
Note. The result of the sensitivity quality control product is judged. the detection line (T) and the quality control line (C) have colored bands.
5.2 Physical properties
5.2.1 Appearance
1 piece of test paper is randomly selected and observed under natural light. It should meet the requirements of 4.1.1
5.2.2 Film strip width
One test strip is randomly selected, and the width of the test strip is measured with a vernier caliper, which should meet the requirements of 4.1.2.
5.2.3 Liquid moving speed
Operate according to the instructions, start timing with a stopwatch from the time the test paper is added to the sample liquid, until the liquid reaches between the E zone and the F zone shown in Figure 2.
Stop timing at the boundary line between the two, the time used is recorded as (t), use a vernier caliper to measure the length of (zone A, zone B, zone E), and mark it as (L), then
Calculating L/t is the moving speed, and the result should meet the requirements of 4.1.3.
5.3 Accuracy
Detect cTnI positive quality control products and operate according to the instructions. The results should meet the requirements of 4.2.
5.4 Repeatability
Detect the cTnI positive quality control product at the same concentration and operate according to the instructions. The result should meet the requirements of 4.3.
5.5 Analysis specificity
Detect cTnI-specific quality control products and operate according to the instructions. The results should meet the requirements of 4.4.
5.6 Minimum detection limit
Detect cTnI sensitivity quality control products, operate according to the instructions, and the results should meet the requirements of 4.5.
5.7 Stability
Take the test paper of the same batch number and place it at 37°C for 20 days, and test according to the methods shown in 5.3 to 5.6.The result should meet the requirements of 4.6.
6 Inspection and judgment
6.1 Reagent (kit) inspection type
The kit inspection is divided into factory inspection and type inspection.
6.2 Factory inspection
The factory inspection items are 4.1~4.5, and the factory can be delivered only after the inspection is qualified; if any of the inspection results does not meet the requirements, the inspection
If the re-inspection is still unqualified, the batch of products shall be determined as unqualified.
6.3 Type inspection
Type inspection items are all items, and each batch of products shall be inspected for all items according to this standard. In one of the following situations, you should enter
