Rapid Covid Test - what is it and how the test is done
With the pandemic caused by COVID-19 (Coronavirus), the spread of tests and swabs to detect infection from the virus has become the new normal. The Rapid Covid Test or Covid Antigen Test is one of these rapid tests that allows to confirm if a person is positive or negative to COVID-19 getting the result in no time.
How does a Rapid Covid Test work?
A Covid antigen test kit resembles a pregnancy test. This test is performed using a sample from the nose or throat using a swab provided in the kit. The swab with the collected sample (fluid) is then deposited into a test tube and poured onto a self-absorbing pad. The fluid is drawn in through the capillary action from this pad until it is placed on a strip coated with Covid antibodies.
If the person's oropharyngeal sample contains the virus, a coloured line appears indicating the patient is positive.
When you should do a Covid Antigen Test
A Covid Lateral Flow Test is widely used to show that you are not infected when travelling or going abroad. The test may, in fact, be required by airlines before departure.
It is usually recommended that a person takes a quick antigenic swab for Covid if they have one or more suspicious symptoms such as fever, cough, congestion, shortness of breath, muscle aches, loss of taste or smell, diarrhoea, nausea, or vomiting.
