Simple nasal swab
Virtually everybody knows how to perform a COVID-19 antigen test on themselves now, but it is still important to read the instructions as there are variations in how to sample and how long the tests take to run.
Unlike the earlier versions of antigen rapid tests, the Healgen Antigen Self-Test, requires only a swab from your nostril rather than the nasopharyngeal swab that had to be taken from behind the nostrils and tonsils. It shouldn't hurt at all!
To make sure you have enough sample in the mixture needed to run the test, make sure you swirl the swab tip with your buffer solution several times and leave for a minute before squeezing the tube to extract as much sample as possible. If this is not performed correctly, there is a risk of a false negative.
If you get a positive test result (2 lines) it means that the proteins that are in the SARS-CoV-2 virus have been detected in your sample and you are very likely to have COVID-19 infection. In the UK there are now no rules to self-isolate, but it is important to be considerate to others. Although the Omicron variant is milder than the original wild Wuhan strain, it can still cause more severe illness in those who are more clinically vulnerable and the elderly
If you get a negative test result, this means the test did not detect any infection. It is important to consider if you have sampled and extracted the sample from the swab sufficiently and also, if you have very early infection, before symptoms develop.
If you are in any doubt, you should test again a day or two later.
