The novel coronaviruses belong to the β genus. COVID-19 is anacute respiratory infectious disease. People are generallysusceptible. Currently, patients infected by the novel coronavirusare the main source ofinfection; asymptomatic infected people canalso be an infectious source. The main symptoms include fever,fatigue, loss of smell and dry cough. Nasal congestion, runny nose,sore throat, myalgia and diarrhea are found in a few cases.SARS viral antigen is generally detectable in upper respiratoryspecimens during the acute phase of infection. The Coronavirus Ag. Rapid Test is a rapid screening tool to detect the presence of SARSviral antigen in the form of a visually interpreted result withinminutes.The Coronavirus Ag Rapid Test Cassette (Swab) is an in vitro immunochromatographicassay for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 indirect nasopharyngeal (NP) swab specimens directly from individuals who are suspected of COVID-19 by their healthcare provider within the first ten days of symptom onset. It isintended to aid in the rapid diagnosis of SARS-CoV-2 infections. Negative results frompatients with symptom onset beyond ten days, should be treated as presumptive andconfirmation with a molecular assay, if necessary, for patient management, may be performed. The Coronavirus Ag Rapid Test Cassette (Swab) does not differentiatebetween SARS-CoV and SARS-CoV-2.Non-invasive Simple to use Convenient, no devices required Rapid, get result in 15 minutes Stable, with high accuracy Inexpensive, cost-efficiency Passed CE ,ISO13485 ,European approved white listSwab(nylon flocked), test card, etcInfectious Disease/Virus Antigen Test Kit (Colloidal Gold lmmunochromatography) COVID-19 Antigen Rapid Test is a rapid device for the qualitative detection of SARS-CoV-2 antigens in nasopharyngeal and nasal.
