Antigen Test - what is it and how the test is done
With the increased risk of every other person developing the COVID-19 virus due to its increased prevalence, testing for Coronavirus has become the new normal.
Thankfully, self-testing kits have now been introduced to the public, making the entire Covid testing process more straightforward and hassle-free.
The Covid Rapid Antigen Test or the Lateral Flow Test is a quick test that allows a person’s COVID positive or negative status to be confirmed in no time. The testing kit resembles a pregnancy urine test.
This test is performed using a sample from the nose or throat using a swab that comes in the kit. The swab with the collected sample (fluid) is then deposited in a tube and poured on a self-absorbent pad.
The fluid gets sucked up through capillary action from this pad until it is placed on a strip coated with Covid antibodies. If the oropharyngeal sample of the person contains the virus, a coloured line appears, marking the patient as positive.
The Lateral Flow Test for COVID has transformed the testing mechanism for Covid and made it much easier for everyone to get it done in no time!
