We have recently talked about how self-monitoring, together with vaccination, can currently be a perfect combination for reducing the pressure on healthcare facilities and making it easier to live with the virus. The initiative put in place by the Emilia region represents the first example of total trust by an institutional body in the good sense of the citizens, which could increase the sense of responsibility towards oneself and towards others that has been emerging during these years of pandemic. But let us now see how to use these do-it-yourself covid tests.

How to do a covid self-test

In its initiative, the Emilia region has drawn up a list of self-tests valid for the purpose of self-certification of Covid positive/negative status, which is published on the website and available to citizens. The list includes some tests such as HOTGEN 2019-NCOV AG TEST. The test kit contains a swab to take the sample from the front of the nose, a tube containing lysis buffer, and a card for analysing and reading the result.

The instructions for using this do-it-yourself covid test are very simple and interpretation of the result is immediate (only 15 minutes). Once the sample has been taken with the swab provided in the kit and dissolved in the tube containing the lysis solution for approximately 15 seconds, a drop is placed on the test card in the area designated with the letter S. The sample migrates along the test card and, in the presence of Sars-Cov-2 infection, a coloured line appears at the band designated with the letter T (test) and one at the band designated with the letter C (Control).

The latter should always be present when performing the test, as it is an indication that the test has been performed correctly.

The antigenic tests are based on the detection of the N protein contained within the capsid of the Sars-Cov-2 virus and not the Spike protein, which is responsible for anchoring the virus to the receptor on human cells and is the site of the different mutations that characterise the Sars-Cov-2 variants.

Because of their ease of use, the possibility to frequently perform them at home, and cheaper prices than professional swabs, self-tests could prove to be an excellent resource to support the activities of healthcare personnel, and on national infection tracking.
