Product Description

OEM Covid 19 Antigen Rapid Test Kit CE Approved One Off Use


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.



The Test is a lateral flow immunoassay intended for the qualitative detection of nucleocapsid protein antigen from 2019-nCoV in saliva specimens directly collected from individuals who are suspected of COVID-19.

Results are for the identification of 2019-nCoV nucleocapsid protein antigen. Positive results indicate the presence of viral antigens, but clinical correlation with patient history and other diagnostic information is necessary to determine infection status. Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease.

Negative results should be treated as presumptive, and do not rule out 2019-nCoV infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. Negative results should be considered in the context of a patient’s recent exposures, history, and the presence of clinical signs and symptoms consistent with COVID-19, and confirmed with a molecular assay.

  • 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.

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.
