Product Description

2019 nCoV Ag Saliva Rapid Test Card

How do they work?

The kits include a swab for people to insert into their nose — but usually not as deeply as the traditional tests — and a test card or portable device where the sample is inserted and automatically analyzed. Some of these devices connect to the internet via Bluetooth.


Like other testing options, some of the new products rely on antigen testing, while others on molecular testing.


An antigen test — which detects specific proteins from the virus — can offer faster results with less lab work, but it’s less sensitive than a molecular test. Positive results are “usually highly accurate,” while negative results may need to be confirmed with a molecular test, the FDA noted.


A molecular test detects the virus’s genetic material and is “typically highly accurate,” according to the agency. Both types of tests diagnose an active coronavirus infection.


Forman, who has been testing an at-home option that hasn’t received FDA authorization yet, said there can be issues with people swabbing themselves incorrectly — a user error he's committed a couple of times.


This test uses double-antibody sandwich to legally detect the antigen of novel coronavirus (2019-nCoV) in saliva samples. During detection, the gold labeled anti-2019-nCoV monoclonal antibody in the labeling pad binds to the 2019-nCoV antigen in the sample to form a complex, and the reaction complex moves forward along the nitrocellulose membrane under the action of chromatography, it is captured by the anti-2019-nCoV monoclonal antibody pre-coated by the detection zone (T) on the nitrocellulose membrane, and finally a red color reaction line is formed in the T zone. If the sample does not contain 2019-nCoV antigen, a red color reaction line cannot be formed in the T zone. Regardless of whether the sample to be tested contains 2019-nCoV antigen, a red reaction line will always form in the quality control area (C).

Materials required but not provided

  • Timer



  • 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.



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.


*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





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.


2019 nCoV Saliva Rapid Test Card 1


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.



  • 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.



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. The results showed no cross reactivity with the following specimen.


4. Interference Substances

The test results do not be interfered with the substance at the following concentration:



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.
