Product Description

COVID 19 Rapid Lateral Flow Antigen Test Kit for Medical Center

What is a lateral Flow Antigen Test Kit?

2019-nCoV Rapid Lateral Flow Antigen Test Kit is an immunochromatography based one step in vitro test. It is designed for the rapid qualitative determination of SARS-CoV-2 virus antigen in nasopharyngeal swab specimens. 2019-nCoV Rapid Lateral Flow Antigen Test Kit cannot be used as the basis to diagnose or exclude SARS-CoV-2 infection.

 

The Principle:

2019-nCoV Rapid Lateral Flow Antigen Test is an immunochromatographic lateral flow device that employs the principle of double antibody sandwich method. Colloidal gold conjugated ant -SARS- CoV-2 antibodies are dry-mobilized on the test device. When the specimen is added, it migrates by capillary diffusion through the strip to re-hydrate the gold conjugate complexes. If present at or above the limit of detection on, SARS-CoV-2 viral antigens will react with the gold conjugate complexes to form particles, which will continue to migrate along the strip until the Test Zone (TJ where they are captured by the immobilized ant -SARS-CoV-2 antibodies to form a visible red line.

 

If there are no SARS-CoV-2 viral antigens in the spec men, no red line will appear in the Test Zone IT). The gold conjugate complexes will continue to m grate alone until being captured by immobilized antibody in the Control Zone (CJ to form a red line, which indicates the valid ty of the test.

  • Timer

 

STORAGE AND STABILITY

  • Store the test as packaged between 2-30°C.
  • The Test stable until the expiration date printed on the outer packing, the product will be expired after 24 months.
  • Do not use beyond the expiration date.
  • Do not freeze any contents of the test
  • The test must remain in the sealed pouch until use.

 

TEST PROCEDURE

Before test, please read the instructions carefully.

  • Take the cassette to equilibrate to room temperature.
  • Unpack the aluminum foil bag, take out the cassette.
  • Insert the absorber end of the cassette into mouth. Make sure cassette is horizontal statement.

  • Actively swab the inside of the mouth and tongue to collect oral fluid.
  • Remove the absorber end from the mouth when the purple color move across the result window in the center of the test device.
  • Wait for 10 minutes and read the results.

NOTE:

*When sampling, gently hold it in mouth and let saliva naturally adsorb on the sponge.

*Do not eat, drink, or smoke prior to the test for at least 30 Minutes.

*Any saliva specimen is appropriate for testing but the saliva specimen collected in the morning, before mouth rinsed, eating or drinking, is recommended

 

 

 

INTERPRETATION OF TEST RESULTS

This product can only perform qualitative analysis on the detection object.

Positive Result:

If both C and T lines are visible within 10 minutes, the test result is positive and valid.

Negative Result:

If test area (T line) has no color and the control area displays a colored line, the result is negative and valid

Invalid Result:

The test result is invalid if a colored line does not form in the control region. The sample must be re-tested, using a new test.

INTERNAL CONTROL

The test contains a built-in internal control in the test card. A color band appearing in the control region (C) is designed as an internal control. The appearance of the control line confirms that sufficient flow has occurred, and that the test card is working normally. If the control line does not appear within 10 minutes, it is considered an error in the test result and it is recommended to test again with the same sample and a new device.

 

LIMITATIONS

  • The result of the test should not be taken as a confirmed diagnosis, for clinical reference only. Judgement should be made along with RT-PCR results, clinical symptoms, epidemiological information, and further clinical data.
  • The Test performance depends on the amount of virus (antigen) in the sample and may or may not correlate with viral culture results performed on the same sample.
  • The test must be equilibrated to room temperature (18℃~26℃) before used, otherwise the results may be incorrect
  • A negative test result may occur if the level of antigen in a sample is below the detection limit of the test.
  • Failure to follow the Test Procedure may adversely affect test performance and/or invalidate the test result.
  • React less than 10 minutes may lead a false negative result; React more than 10 minutes may lead a false positive result.
  • Positive test results do not rule out co-infections with other pathogens.
  • Negative test results are not intended to rule in other viral or bacterial infections.
  • Negative results should be treated as presumptive and confirmed with a molecular assay.
  • Clinical performance was evaluated with fresh samples.
  • Users should test specimens as quickly as possible after specimen collection.

 

PERFORMANCE CHARACTERISTIC

1. Clinical Verification

The performance of Test was established with 232 sample collected from symptomatic patients, who with symptoms onset within 7 days.

2. Limit of Detection

The experimental results show that for the virus culture concentration above 100 TCID50/mL, the positive rate of detection is greater than or equal to 95%. For the virus culture concentration of 50 TCID50/mL and below, the positive rate of detection is lower than 95%. So, the limit of detection of the Test Card is 100 TCID50/mL.

3. Cross-reactivity

Cross-reactivity of the test card was evaluated. 

4. Interference Substances

 

5. Precision

1. Test 10 replicates of negative and positive by using the reference materials of enterprises. The negative agreement and the positive agreement were 100%.

2. Test three different lots kits including positive and negative reference materials of enterprises. The negative results and the positive results were 100%

6. Hook Effect

The Test Card was tested up to 1.6 × 105 TCID50/ml of heat-inactivated 2019-nCoV strain and no high-dose effect was observed.
