ImCoV-Ag COVID-19 Antigen Rapid test device has two precoated lines, 'C' Control line and 'T' Test line on the surface of the nitrocellulose membrane. Both the control line and test line in the result window are not visible before applying any specimens. Mouse monoclonal anti-SARS-CoV-2 antibody is coated on the test line region and Goat anti-Mouse IgG antibody is coated on the control line region. Mouse monoclonal anti-SARS-CoV-2 and Mouse IgG antibody conjugated with color particles are used as detectors for the SARS-CoV-2 antigen device. During the test, SARS-CoV-2 antigen in the specimen interacts with monoclonal anti-SARS-CoV-2 antibody conjugated with color particles making an antigen-antibody color particle complex. This complex migrates on the membrane via capillary action until the test line, where it will be captured by the mouse monoclonal anti-SARS-CoV-2 antibody. A colored test line is visible in the result window if SARS-CoV-2 antigens are present in the specimen. The intensity of the colored test line varies depending on the amount of SARS-CoV-2 antigen present. If SARS-CoV-2 antigens are not present, no color appears in the test line. The control line is used for procedural control and should always appear if the test procedure is performed properly.

A lateral flow immuno-chromatographic test for the qualitative detection of SARS-CoV-2 antigen in human nasopharynx. For use by healthcare professionals to aid in early diagnosis.

Step 1: Sample collection and extraction. Step 2: Test operation. Refer to the Instructions for Use (IFU) for the full step-by-step procedure with diagrams.
