SARS-CoV-2 Antigen Test Kit (colloidal gold method) 1 piece

Product Details:


Product Description


The kit is immunochromatographic and uses double-antibody sandwich method to detect SARS-CoV-2 antigen. During

detection, the treated samples are loaded into the sample wells of the test card. When the concentration of SARS-CoV-2

antigen in specimen is higher than the minimum detection limit, the viral antigen will form complexes with labeled

antibodies first. Under chromatography, the complexes move forward along the nitrocellulose membrane till captured by

pre-coated monoclonal antibody of SARS-CoV-2 in detection zone on nitrocellulose film (T) to form a pink/purple reaction

line on the detection zone, at this point the result is positive; conversely, if there is no viral antigen or the concentration of

antigen in specimen is below the minimum detection limit, no pink/purple reaction line appears in the detection zone, at this

point the result is negative. Regardless of whether the sample contains viral antigens or not, a pink/purple reaction line will

appear in the quality control zone (C), the pink/purple reaction line that appears in the quality control zone (C) is the

criterion for determining if the chromatography process is normal.
