The experimentation of the self-diagnostic tests begins in Veneto. Starting November 16, around 5,000 kits will be tested in four or five microbiology laboratories in Veneto, led by the Treviso microbiology and virology unit led by Roberto Rigoli. The test results will then be submitted to the ISS, which is responsible for final validation. There are high expectations around these new tests because, in the presence of a high number of infections, they would allow a considerable saving of time and costs and therefore a better management of the emergency.
Kit similar to a pregnancy test
The kit is similar in operation to a pregnancy test. The first element present is obviously the cotton swab for the swab, which is passed through the inside of the nostrils but without having to reach the deepest parts of the nasal septum. Then, the cotton swab must be dipped in a reagent contained in a plastic test tube present in the kit. After a few minutes, the same liquid will be poured into a small box tester. Maximum 15 minutes and some colored lines will appear.

Special application
But what do you do after inserting the swab into the reagent container and getting the result? The “Zero Covid Veneto” biosurveillance application, already approved by the Regional Council, must be opened and the results of the tests must be reported so that it is accessible to the regional health system.
Distribution and costs
If the self-test kit passes the test and is validated, it will be available at the pharmacy. Those that have already obtained the green light from the FDA (Food and Drug Administration) in the United States cost about $ 5. And the president of Veneto Luca Zaia himself spoke of the cost of “a few euros.” A requirement that, if the test turns out to be reliable, can really transform it into a tool for mass screening.
Reliability
The truth at this time is that the new technology of the DIY kit represents a great saving of time but also of economic expense. Its use in a large number of people is the most effective strategy to improve its diagnostic potential. The greatest difficulty, as with all rapid tests, is related to false negatives. Since the research is not directed at the genetic material, as is the case with molecular swabs, but rather refers to the typical surface proteins of the virus, negative detection of the same proteins is less reliable. Although molecular swabs remain the safest source of Covid-19 diagnosis at this time, the increasing number of infections requires faster mass screening intervention. And the first phase of case skimming is essential to save time and resources.
