The Rapid Response® COVID-19 Antigen Rapid Test Pen (Saliva) is an in vitro immunoassay. It is the World’s First ‘No-Spit’ Saliva Antigen Rapid Test Pen for SARS-CoV-2! The COVID-19 antigen rapid test pen is for the direct and qualitative detection of SARS-CoV-2 viral nucleoprotein antigens from saliva samples through a visual interpretation of colour development. They are manufactured in Canada and are extremely user-friendly for rapid results in 15 minutes. These antigen rapid test pens are available at a low-cost and can be shipped immediately.

Bring devices to room temperature (18-30°C) before use.
Anti-SARS-CoV-2 antibodies are immobilized on the test region of the nitrocellulose membrane. These antibodies are conjugated to coloured particles that 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.
These COVID-19 Antigen Rapid Test Pens have been clinically tested in Switzerland. The results are shown below:

These Antigen Rapid Test Pens were also compared to real time PCR tests. According to ‘Regulation 3 on Measures to Control Coronavirus (Covid-19) (Covid-19 Regulation 3) of 19 June 2020 (as of 15 March 2021’, Chapter 3: ‘Criteria for clinical validation of Sars-CoV-2 rapid tests for professional use according to the screening standard and of Sars-CoV-2 self-tests-, the sensitivity needs to be at least 80% for the antigen rapid test pens to be available for use. The results can be seen below which demonstrates that the sensitivity of these pens is 100% accurate when compared with the real time PCR values:
Individually packaged saliva collection pen and extraction buffer cap in the same foil pouch, can come in a 5 pack or 20 pack depending on your needs.
