This kit is used for the in vitro qualitative detection of novel coronavirus (2019-nCoV) S-RBD IgG antibodies in human whole blood samples. 

This kit is suitable for the detection of neutralizing antibodies against novel coronavirus pneumonia and can better monitor herd immunity. and protective immunity, as well as to evaluate vaccine efficacy during clinical trials and after mass vaccination. The results are for clinical reference only. 

This kit is suitable for distinguishing between people with protective immunity after vaccination with the novel coronavirus inactivated vaccine and those vaccinated with unit vaccine/mRNA vaccine. The results are for clinical reference only.

This kit is intended only for use by qualified clinical laboratory personnel who have received specialized training and instruction in the techniques of in vitro diagnostic procedures.

This reagent uses immunochromatography technology and capture method to detect novel coronavirus (2019-nCoV) S-RBD IgG antibodies.

 During detection, add the processed sample to be tested to the sampling hole of the test card. When the sample to be tested contains the new coronavirus (2019-nCoV) S-RBD IgG antibody, and the antibody concentration is higher than the minimum detection limit,Within a limited time, the antibodies in the sample and the colloidal gold-labeled anti-human IgG antibody form a reaction complex. Under the action of chromatography, the reaction complex moves forward along the nitrocellulose membrane and is captured by the recombinant antigen pre-coated in the detection area. A red/pink reaction line forms on the detection area; on the contrary, when the sample to be tested does not contain the new coronavirus (2019-nCoV) S-RBD IgG antibody, or the antibody concentration is lower than the minimum detection limit, there is no pink/pink reaction line in the detection area. A purple-red reaction line appears. 

Regardless of whether the sample contains novel coronavirus (2019-nCoV) antibodies, a red/purple-red reaction line will be formed in the quality control area (C). The red/purple-red reaction line displayed in the quality control area (C) is the judgment chromatography standards for whether the process is normal.
