Rapid Test Kit Antigen Self Test in 15 mins Nasal Swab

Intended Use

COVID-19 Antigen Rapid Test Cassette is for in vitro qualitative detection of specific antigens to SARS-CoV-2 present in human throat or nasal cavity. It cannot be used as the basis for the diagnosis and exclusion of COVID-19.


This reagent is used to detect cases with suspected symptoms of COVID-19 within 7 days. If suspected symptoms are more than 7 days, it is recommended to test with COVID-19 antibodies or nucleic acid reagents.



This kit uses double antibody sandwich immunoassay to detect specific antigens to SARS-CoV-2 in human throat or nasal cavity. The membrane was precoated with SARS-CoV-2 specific antibody on the test zone and goat anti mouse IgG antibody on the control zone.


During the test, the specimen is allowed to react with SARS-CoV-2 specific antibody-colloidal gold particles conjugate, which was predried on the test. The conjugate binds to the SARS-CoV-2 forming an Antibody~Antigen complex.


Principle of testing
This primer and probe sets are designed for the detection of the conserved sequences of SARS-CoV-2 (ORF1ab gene, N gene and E gene). The kit contains an Internal Control that is used to assess specimen quality. Real-Time PCR technology utilizes polymerase chain reaction (PCR) for the amplification of specific target sequences and target specific probes for the detection of the amplified RNA. The probes are labelled with
fluorescent reporter and quencher dye


Something you need to learn about:
1) What is the difference between an antigen test and a molecular test?
An antigen test detects specific proteins on the surface of the virus. These tests are quicker and less expensive, but have a higher chance of missing an active infection, according to the FDA.
A molecular (PCR or polymerase chain reaction) test detects the virus’s genetic material. These tests require a more complex technology to get results, and it usually takes a day or two to get those results (depending on lab capacity, results may take up to a week).
If an antigen test shows a negative result and you have reason to believe you may have the virus (because of symptoms or exposure), your doctor may order a molecular test to confirm the results.

2) Which tests are more accurate?
No test is 100% accurate, but the molecular tests are considered to be more accurate than the antigen tests, according to available research.
According to the FDA, an antigen test cannot “definitively rule out active coronavirus infection,” but positive results are “highly accurate” (negative results may require a confirmation test).
Harvard Medical School wrote in August that the reported rate of false negatives with molecular testing is as low as 2% and as high as 37%. A molecular test using a deep nasal swab will have fewer false negative results than samples from throat swabs or saliva, they say.
For antigen testing, Harvard noted that the reported rate of false negative results can be as high as 50%, but that the FDA has granted emergency use authorization for a more accurate antigen test.
In general, some of the issues that may affect the accuracy of a test include ineffective swabbing, contamination or mishandling of the sample, or problems with the testing chemicals, according to the FDA.

3) If antigen tests are less accurate, why would we use them?
Experts say the value in the rapid antigen tests is in the frequency of the testing rather than the accuracy, with repeated testing recommended. According to Science, getting a false negative in an antigen test two or three times in a row is rare. This strategy lines up with the NPR report mentioned above, which would employ daily testing of those in high-risk areas.


4) Who must be tested for COVID-19?
As per the Minister’s Directive: COVID-19: Long-Term Care Home Surveillance Testing and Access to Homes (Minister’s Directive) effective January 8, 2021, all staff, student placement and volunteers working in long-term care homes must be tested regularly in accordance with the Minister’s Directive, unless the exception for individuals who have previously had laboratory confirmed COVID-19 applies. The testing requirements in the Minister’s Directive include all individuals working in long-term care homes who are: • Staff as defined in the Long-Term Care Homes Act, 2007 • Volunteers as defined in the Long-Term Care Homes Act, 2007 • Student placement, meaning any person working in the long-term care home as part of a clinical placement requirement of an educational program of a college or university, and who does not meet the definition of “staff” or “volunteer” under the Long-Term Care Homes Act, 2007. The Minister’s Directive also includes additional testing and documentation requirements for general visitors, caregivers and support workers.
