What is a COVID-19 Antigen Test?

Sugentech’s SGTi-flex COVID-19 Ag is a rapid, lateral flow antigen test and it is used as an aid in the rapid diagnosis of SARS-CoV-2 viral infections. It can serve as an effective tool to help identify infected individuals. It directly detects the presence or absence of specific proteins (antigens) on the surface of the SARS-CoV-2 from nasopharyngeal and oropharyngeal swab specimens. The test which is easy to use doesn’t require laboratory instruments; it can be conducted by a suitably qualified medical professional such as a nurse, doctor or pharmacist. It delivers results in 20-30 minutes

Who is the test for?

The test is for everyone who wants to know if they contracted the COVID-19 Virus and wants to rule out an active COVID-19 infection. It can be used as a test before safely seeing an elderly relative or a group of friends as well as a proof of status before returning back to work. This test is not suitable as a “Fit to Fly” certificate. If you need a negative COVID-19 test in order to be able to travel you have to conduct a COVID-19 PCR test.

How does the test work?

The SGTi-flex COVID-19 Ag is easy to administer and delivers results quickly using the nasopharyngeal swab method. Once a sample is collected, the swab is inserted into a tube with special liquid (buffer solution) to extract the target molecule. This liquid is then dispensed onto a test cartridge and in 20-30 minutes, a positive or negative result is clearly indicated. A detailed and comprehensive leaflet is provided with every box of test kits.
