SARS-CoV-2 Antigen Swab Test
NOVAtest ® SARS-CoV-2 Antigen Swab Test kits are intended to detect Sars-CoV-2 virus before symptoms appear, thus help to diagnose the infection of Sars-Cov-2 infection and control the spread of the virus.
SARS-CoV-2 Antigen Rapid throat/nasal swab test kit is an rapid immunoassay kit based on Colloidal Gold Immunochromatography principle, which uses the double antibody sandwich method to detect the novel coronavirus (SARS-CoV-2) antigen in the specimen from human throat and nasal swab. The test kits are intended to detect COVID-19 virus before symptoms appear, thus help in the diagnosis of COVID-19 infection, and help to control the epidemic of COVID-19 virus.
Sars-Cov-2 Test Kit for Self-Testing
This Sars-Cov-2 antigen Nasal/throat swab rapid test is easy to use; no extra reagent is needed; the result is easily read visually; the interpretation of the result is easy and simple; result can be obtained within 15 minutes. Because of these characters, this SARS-COV-2 Antigen test kit can be used as a point-of-care screening kit. And actually, a layman can easily perform this rapid test device.
With the improvement of the test kits, especially with the improvement of the sensitivity, the specimen collect points are not restricted to the inner organs like nasopharynx cavity. Anterior nasal swab and Oropharyngeal Swab can also be used. This makes the collection of specimen much easier.
After reading the leaflet carefully, and if the assay procedures in the instruction leaflet can be followed strictly, the test can be totally used as self-testing device. Actually, our SARS-COV-2 antigen swab test kit has been approved by German authority to sell to the self-testing market (No.: 5640-S-122/21).
Variants and SARS-COV-2 Antigen Test
Three variants of Sars-Cov-2 virus have been found.
Variant P.1 contains 17 unique amino acid changes, three deletions, four synonymous mutations, and one 4nt insertion. Three of these mutations are of known biological importance: K417T, E484K, and N501Y.
VOC1 and VOC2 both contain multiple nucleotide changes across the genome which result in amino acid substitutions and other changes in different proteins. These include a large number of changes in the spike protein and a lesser number in the nucleocapsid protein.
The target antigen of our SARS-Cov-2 Antigen swab test and saliva test kits are the nucleocapsid protein, where there is little change. The antibody-antigen reaction works well with the variants. Therefore our products can detect the three above mentioned variants of Sars-Cov-2 virus.
