Will I have gone looking to the right point? If I don’t feel pain or discomfort, will I have done everything right? These are the questions that come naturally after performing a DIY swab. And the concept is the same if it is a second person who helps the subject to be tested, most of the time not an expert on the subject. Yes, because taking a test against Covid is not for everyone. At the base there is a technique that was not born with the pandemic, but which is taught in the health sector to search for other viruses or pathogens of different nature. This is why often the reliability of a result that emerged thanks to a do-it-yourself tampon is judged much lower by those who know it. It is because often the movement is simply wrong, frustrating efforts and good will. So how do you make a good anti-Covid buffer? Lor the pharmacists always explain, who in two years got carried away just like the doctors in hospitals.
«The complexity of the execution of a tampon – explains Luca Degrassi, pharmacist from Udine – is the main reason why we always recommend to always do an official monitoring with a competent person. There is a very high variability due to the applied method ». In short, making mistakes is easier than you think. It is not enough to insert the stick in the two nostrils to have a credible result. “There are different techniques – continues the expert – and the best one is certainly represented by the nasopharyngeal investigation”. So room for tears, because for a good test you have to “go all the way”, accessing the small canal that connects the nostril to the pharynx. And that is why the tampon is called nasopharyngeal. Otherwise the name wouldn’t make sense either. “Just in correspondence with that channel – explains Degrassi – there is an area that has the most favorable conditions for the survival of viruses, therefore also of the one that causes Covid. It is an area less exposed to external conditioning ». To give an example, a nostril is subject to stimuli much more frequently than what happens in the pharynx. Just think of a sneeze or the classic nose blow. “All actions that can alter the presence of the virus you want to look for with a swab”, is the expert’s warning. One of the main fears of those who have to undergo a test against Covid is the risk of experiencing pain. «But if done in the right way – concludes Degrassi – even a nasopharyngeal swab does not cause any pain. Much more risky, on the other hand, to try to get by without having any competence in the matter ». Not only do you risk experiencing pain, but the probability of finding yourself with a result very far from the truth increases exponentially. BUT
