SARS-CoV-2 Antigen Rapid Test

Introducing the SARS-CoV-2 Rapid Antigen Test

The Flowflex SARS-CoV-2 Antigen Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection of the nucleocapsid
protein antigen from SARS-CoV-2 in nasal swab specimens directly from individuals who are suspected of an active COVID-19 infection.

What is the Test?

  • A rapid test for the detection of SARS-CoV-2 nucleocapsid antigens in anterior nasal swab specimens.

* For general use. Self testing.


What is the Disease?

  • SARS-CoV-2 belongs to the Coronaviridae family and is closely related to the SARS coronavirus that appeared in 2002/2003. The virus was first identified in humans in Wuhan, China, at the end of 2019, and is transmissible from person to person. 
  • The main route of transmission is droplet infection, but infections via aerosols and smear have also been described. 
  • The incubation period is usually three to seven days, up to a maximum of fourteen days. SARS-CoV-2 infected patients are often asymptomatic or experience only mild symptoms such as a dry cough, fever, and shortness of breath. 
  • Some of the infected persons develop a severe pneumonia, which can lead to death.
