[Intend Use]

This rapid test cassette reagent is used for in vitro qualitative diagnostic of SARS-CoV-2 IgG/IgM in

human serum, plasmaor whole blood specimen. The rapid diagnostic test kit is intended for use of screening test

and aid in the diagnosis of SARS-CoV-2viral infections.

rapid test cassette reagent kits brief intro.jpg 


[Principle]

This antibody rapid detection kit applies the chromatographic immunoassay technology to capture the SARS-CoV-2 antibodies IgG/IgM in human serum, plasma or whole blood specimen. In the test when there is SARS-CoV-2antibodies IgG/IgM in the specimen and its concentrate exceed the minimum detection limit, the antibodies will bind to antigen marker and are captured by the second antibody (Anti-U chain antibody 1 anti IgG antibody) in the test area (T), forming a red reaction line. At this time, the result is positive; otherwise, the result without the color band is negative. Under normal detection, the quality control area (C) should be colored to indicate that the detection is effective..


[Components]

The reagent consists of a test cassette, sample diluent (dropper), dropper tube (optional), etc.

1.        Test cassette: SARS-CoV-2 antibodies IgG/IgM test strip and plastic cassette. The test strip is made up of nitrocellulose membrane, sample pad, binding pad, absorbent paper, and PVC board.

2.        Specimen diluent (dropper)

Note: Do not mix the component of kits from different lot in order to avoid error test results.

 

[Storage & Expiry]

The unopened kit should be stored at 2~30, and the validity period is 18 months. When open the pouch, the cassette should be used within one hour. When new specimen diluent is used, it should be covered and put

in the dark. It must be used only within expiry.

See product label for production date and expiry date.

 

[Specimen Requirements]
Human serum, plasma or whole blood specimen can be used in the test.
Collection of serum/plasma specimen: after collection, serum and plasma should be separated as soon as possible to avoid hemolysis. After separation, serum and plasma should be tested as soon as possible. If they cannot be used in time, they should be stored at 2 
 ~8  or kept at -20 for the delay in more than 3 days. Before the test, it should be restored to room temperature. Avoid repeated freezing and thawing. It is not recommended to use specimens with severe hemolysis or heat inactivation.
Whole blood collection: use an anticoagulant tube to collect whole blood, or add anticoagulant (heparin, EDTA salt, sodium citrate, and other anticoagulants) into the blood collection vessel first, add and shake the collected blood sample for standby. If they cannot be used in time, they should be stored at 2℃~8℃ for 7 days. Specimen from intravenous left more than 3 days is not suitable for this kt.

 

[Test Procedure]

corona virus samples detection and diagnosis procedure.jpg

Please read thoroughly the instruction before use. The specimens to be tested, kit and other materials shall be restored to room temperature before the test. The test shall be conducted at room temperature.

1.     Open the aluminum foil bag along the tearing line, take out the test cassette and lay it flat.
2. Add 10ul serum/plasma/whole blood specimen to the specimen hole on the cassette, and then add about 100ul (3 drops) specimen diluent to on the cassette.
3. Observe the result within 15 minutes. The result observed after 20 minutes has no clinical significance.

 

[Explanation of test results]

As shown in Figures ①~⑧, the test results are as follows:

Rapid Test Cassette Kits results indications.jpg

1.     Positive: As shown in Figure , clear red C lines, red G and M lines appear in the reaction wellas shown in Figure , clear red C lines, and red G line appears in the reaction well; as shown in Figure As shown, clear red C line and red M line appear in the reaction well.

2.     Negative: As shown in Figure , only a clear red C line appears in the reaction well;

3.     Invalid: as shown in Figure , only red T1 and T2 lines appear in the reaction well; as shown in Figure , only T1 lines appear in the reaction well; as shown in Figure , only T2 lines appear in the reaction well; As shown in Figure , no reaction line appears in the reaction wells, which indicates that the test is invalid. You need to find the cause and retest.

A positive antibody test not only occurred in the primary infection but also increased the reactivity of IgM/IgG antibodies in the secondary infection. The test object of this kit is SARS-CoV2 IgM/IgG antibody, and the results cannot indicate whether there is a new coronavirus in the sample.

 

[Limitations]
The test results are only used as an assisted clinical diagnosis. They are not the only reference for clinical diagnosis. The clinician should also make a comprehensive judgment based on the patient's physical condition, medical history, and other diagnostic items and diagnostic methods.
1. This kit is only for the detection of the specimen from serum, plasma, and whole blood.
2. The accuracy of the test depends on the specimen collection. Inappropriate collect, storage or repeated freeze-thaw cycle of the specimen would affect the test result.
3. This kit is only for the qualitative diagnosis of SARS-CoV-2 IgG/IgM in the serum, plasma, and whole blood specimens and cannot determine the concentration of antibodies. Please use other devices for quantitative diagnosis.
4. The test results of this kit are only for clinical reference, and shall not be the only basis for clinical diagnosis and treatment. The clinical management of patients should be considered comprehensively in combination with their symptoms/signs, medical history, other laboratory tests, and treatment reactions.

4.     Due to the limitation of the methodology of the antibody detection kit, it is recommended to use nucleic acid detection or virus culture identification method to confirm positive test results.
6.Analysis of possibilities for false-negative
a) Inappropriate specimen collection, transit or treatment, or extremely low concentration of antibodies in the specimen may lead to a false-negative result.
b) The mutation of the virus gene may lead to the change of antibody determinants, which may lead to a false-negative result,
c) The best specimen type and the best sampling time
(peak virus titer) after infection have not been verified. Therefore, it is possible to avoid false-negative when samples are collected from the same patient in several timed and multiple locations.

 

[Performance Indicators] 

1.     Positive reference rate: three positive specimens of SARS-CoV-2 antibodies were detected. all results should be positive.

2.     Negative reference rate: three negative specimens of SARS-CoV-2 antibodies
