Product Details

SARS-CoV-2 Antigen Rapid Test (Covid testing)

A rapid test for the qualitative detection of antigens to the novel coronavirus SARS-CoV-2 in human throat and nasal secretions. For professional in vitro diagnostic use only.


The SARS-CoV-2 Antigen Rapid Test (Covid testing) is a rapid chromatographic immunoassay for the qualitative detection of novel coronavirus SARS-CoV-2 in human throat and nasal secretions.


The SARS-CoV-2 Antigen Rapid Test is for detection of SARS-CoV-2 antigens. Anti-SARS-CoV-2 monoclonal antibodies are coated in the test line and conjugated with the colloidal gold. During testing, the specimen reacts with the anti-SARS-CoV-2 antibodies conjugate in the test strip. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with another Anti-SARS-CoV-2 monoclonal antibodies in the test region. The complex is captured and forming a colored line in the Test line region. The SARS-CoV-2 Antigen Rapid Test contains anti-SARS-CoV-2 monoclonal antibodies conjugated particles and another anti-SARS-CoV-2 monoclonal antibodies are coated in the test line regions.

Allow the test device, specimen, buffer, and/or controls to equilibrate to room temperature (15-30°C) prior to testing.

1. Bring the pouch to room temperature before opening. Remove the test device from the sealed pouch and use it as soon as possible.

2. Place the test device on a clean and horizontal surface. Reverse the specimen collection tube, extrude 3 drops of the prepared specimen into the specimen well (S) of the test cassette and start the timer.

See illustration below.
