The Rapid Response® COVID-19 Antigen Rapid Test Pen (Saliva) is an in vitro immunoassay. The assay is for the direct and qualitative detection of SARS-CoV-2 viral nucleoprotein antigens from saliva samples through visual interpretation of colour development. This test is intended for professional use only.

Key Benefits:

First and the only no-spit test dedicated to COVID-19 – Its sponge-like pen tip will collect a sufficient volume of specimen in 2 mins without the need to spit and avoiding uncomfortable nasal/throat swabbing.
ALL IN ONE – No need to waste time setting up a workstation and handle numerous assay components. All you need is one pen that can be used comfortably in any location.

Test Principle 

Anti-SARS-CoV-2 antibodies are immobilized on the test region of the nitrocellulose membrane. Anti-SARS-CoV-2 antibodies conjugated to coloured particles are immobilized on the conjugated pad. A sample is added to the extraction buffer which is optimized to release the SARS-CoV-2 antigens from specimen. During testing, target antigens, if present in the saliva samples, will be released into the extraction buffer individually packed in the kit. Consequently, the extracted antigens will bind to anti-SARS-CoV-2 antibodies conjugated to coloured particles.

As the specimen migrates along the strip by capillary action and interacts with reagents on the membrane, the complex will be captured by the anti-SARS-CoV-2 antibodies at the test region. Excess coloured particles are captured at the internal control zone. The presence of a coloured band in the test region indicates a positive result for the SARS-CoV-2 viral antigens, while its absence indicates a negative result. A coloured band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking is working.
