Rapid antigen tests detect the protein present at the outer surface of the Coronavirus. The total time taken by the test to provide results is 15-30 minutes. Antigen test is a point-of-care test. It means it can be done anywhere, like at the clinic, home, or hospital.
Antigen tests are relatively less expensive. Although it is less sensitive than the RT-PCR test, the antigen test is an effective way to monitor infection in people who are in close contact with COVID-19 infected.
Rapid antigen tests are often used as mass screening tests to detect SARS-CoV-2 infection quickly in containment zones or healthcare settings. It helps in the immediate implementation of infection prevention measures effectively.
A rapid antigen test is a simple test. It comes as a kit, the same as a pregnancy test kit. Before taking the sample, wash your hand for 20 seconds using soap and water. Alternatively, you can use hand sanitizer. After taking the sample swab from the nose and throat, we can transfer it to the extraction tube and finally to the test strip.
