Test Principle

This rapid kit uses fluorescence immunochromatography method to detect SARS-CoV-2 N antigen in human serum. Apply the sample to be tested into the sample hole of the test cassette, the test analyte in the sample will form a complex with the fluorescent microsphere-labelled antibody on the binding pad under chromatography, and the complex will continue to be chromatographed on the nitrocellulose membrane until detection Line (T line), then captured by the detection line antibody. The unbound microspheres are chromatographed to the quality control line (C line) and captured by the antibody on the quality control line. A fluorescent flashlight with a wavelength of 365nm was used to illuminate the observation window. The red fluorescent signal on the T line and the C line at the same time indicates that the SARS-CoV-2 N antigen is positive; only the C line and no T line indicates that the SARS-CoV-2 N antigen is negative. If the C line does not appear, the test result is invalid, and this sample needs to be tested again with another test cassette.

Additional Information

Scientific Background


The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the 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 period is 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. The genome of coronavirus encodes spike protein, envelope protein, membrane protein and nucleocapsid. In the process of viral assembly, N protein binds to viral RNA and leads to the formation of spiral nucleocapsid. N protein is a highly immunogenic phosphoprotein, which is related to viral genome replication and cell signaling. Because of the conserved sequence of N protein, detection of SARS-CoV-2 N protein is of great clinical significance. This rapid kit is used for qualitative detection of SARS-CoV-2 nucleocapsid protein antigen (hereinafter referred to as “SARS-CoV-2” N antigen) in human serum.
