919306127344 SD biosensor Antigen rapid test kit for corona. Number of test per box 25. Antigen Test Result time ( Rapid Kit) 10 to 15 minutes. ICMR approved and FDA , CE , ISO certified. Covid Rapid Antigen Test Kit Viral antigen rapid test kit for the detection of SARS-CoV-2 in human oropharyngeal, nasal, and nasopharyngeal swabs. The test is a lateral flow assay with a colloidal gold reporter, giving results in ten minutes.This Covid Rapid Antigen Test Kit (Colloidal Gold) uses the sandwich immunocapture method and colloidal gold immunochromatography to qualitatively determine the presence of SARS-CoV-2 antigens. During the test, the sample is dropped into the sample well, and SARS-CoV-2 antigens in the sample are bound by colloidal gold-labeled monoclonal anti-SARS-CoV-2 antibodies. These then migrate together to the test area, as the capillary effect draws the fluid up the nitrocellulose test strip. A row of SARS-CoV-2 monoclonal antibodies are coated on the strip at the test area (T line), and these also bind the antigens. The antibody-antigen-antibody-colloidal gold sandwich results in a visible line at the T line, if the SARS-CoV-2 antigens are present in the sample. The quality control area (C line) is coated with goat anti-mouse antibodies that bind the colloidal gold-labeled antibodies, resulting in a visible C line. If the C line does not show any colour, it indicates that the result is invalid, and this patient needs to be tested again.
