COVID-19 rapid test TG-1426

for neutralizing antibodyIgGCOVID-19

This product uses immunochromatographic techniques to qualitatively detect the presence of neutralizing antibodies(RBD IgG) in human whole blood, serum and plasma samples using a Indirect methods. If RBD IgG antibodies are present in the sample to be tested, the colloidalgold-labelled 2019-nCoV antigen binds to the 2019-nCoV antibody in the sample to form a reaction complex, which moves forward along the nitrocellulose membrane under chromatographic action and binds to the Mouse anti-human IgG antibody pre-encapsulated in the detection zone (T) to form a "colloidal gold-2019-nCoV-Ag- RBD IgG Ab-Mouse anti-human IgG Ab" complex, resulting in a red line visible to the naked eye in the T region; In contrast, when a negative sample is tested, no red line is formed in the T region. Regardless of the presence of 2019-nCoV RBD IgG in the sample to be tested, a red line is always formed in the quality control area (C)
