COVID-19 rapid test TG-1425

for neutralizing antibodyCOVID-19serum

This product uses immunochromatographic techniques to qualitatively detect the presence of neutralizing antibodies in human whole blood, serum and plasma samples using a double antigen sandwich method. If RBD antibodies are present in the sample to be tested, the colloidal gold-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 2019-nCoV antigen pre-encapsulated in the detection zone (T) to form a "2019-nCoV-Ag-(2019-nCoV-Ab)- (colloidal gold- 2019-nCoV-Ag)" 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 Ab in the sample to be tested, a red line is always formed in the quality control area (C)
