From the product leaflet on their site:
'The Novel Coronavirus (SARS-CoV-2) Antigen Rapid Test Kit is a chromatographic immunoassay intended for the qualitative detection of the nucleocapsid protein antigen from
SARS-CoV-2 in nasopharyngeal swab, oropharyngeal swab,saliva or nasal swab specimens directly from individuals who are suspected of COVID-19 by their healthcare provider within the first 7 days of symptom onset. It only recognizes the N protein and cannot detect the S protein and its mutation structure. The test provides preliminary test results. Negative results do not preclude SARS-CoV-2 infection and they cannot be used as the sole basis for treatment or other management decision. For in vitro diagnostic use only. Summary The novel coronaviruses belong to the ß genus.COVID-19 is an acute respiratory
infectious disease. People are generally susceptible. Currently, the patients infected by novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation periodis 1 to 14 days,mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases. Principle The Novel Coronavirus (SARS-CoV-2) Antigen Rapid Test Kit is composed of novel Coronavirus monoclonal antibody 2 and goat anti- mouse IgG polyclonal antibody fixed in the nitrocellulose membrane and Novel Coronavirus monoclonal antibody 1 latex-labeled fixed in the release pad. The kit tests Novel Coronavirus SARS-CoV-2 N antigen in human
nasopharyngeal swabs , oropharyngeal swabs ,saliva or nasal swabs with the principle of double antibody sandwich method by latex immunochromatography. When a specimen is added to the sample well, the sample is first mixed with the colored latex-labeled novel coronavirus monoclonal antibody 1 on the release pad, and then migrate on the nitrocellulose membrane. If SARS-CoV-2 N protein antigen presents in the sample, these antigens will bind to coronavirus monoclonal antibody 1 labeled with color latex forming antigen antibodies complex. This complex migrates through nitrocellulose membrane by capillary action. When the complex is captured by the SARS-CoV-2 monoclonal antibody 2 to form a red colored band in the T line, which is a positive result. If no antigen presents in the sample, there will be no red band appearing in the testing region, this is a negative result. The internal control (C band) fixing with goat anti-mouse antibody should exhibit a red band regardless of whether antigen presents in the test.'
