Understanding the covid test (serological, pcr, antigenic) of Sars-Cov2 (and its variants)

How to stay healthy and prevent risks and consequences on your health and public health. occupational disease, industrial risks (asbestos, air pollution, electromagnetic waves ...), company risk (workplace stress, overuse of drugs ...) and individual (tobacco, alcohol ...).

Here is something else! With a little brainwashing or journalistic mediocrity (or both) since:

a) Autotest and antigen are the same
b) There are salivary antigenic self-tests, I did one last week: health-pollution-prevention/positive-saliva-self-test-after-x-hours-what-does-it-mean-t17118.html
So without the need for swabbing


Repeated swab sampling is not without risk!

PCR, antigen or self-test tests: Serious complications have started to be described in the medical literature for a few weeks, in particular breaches of the anterior floor of the base of the skull associated with a risk of meningitis”



PCR, antigen or self-test tests: not without risks for your health

PCR tests, antigen tests or self-tests: many of us no longer count the many use of nasal swabs to validate or rule out a potential infection with SARS-CoV-2. But can these nasopharyngeal samples be dangerous?

(...)


A risk of injury

But then, can this gesture generate health risks? Of course, in the vast majority of cases, the samples go smoothly. And when a problem arises?

"While some complications can be considered benign (inconvenience, pain or bleeding), serious complications have been beginning to be described in the medical literature for a few weeks, in particular breaches of the anterior level of the base of the skull associated with a risk of meningitis”, already described the Academy of Medicine in April 2021.

Data to be taken into account all the more rigorously today when the use of tests is becoming a routine gesture.

What precautions to take?

Before performing a nasopharyngeal test and to avoid any risk of injury:

Make sure that you do not suffer from any “accidental or surgical history of the ENT sphere that could modify the anatomy of the nasal and sinus cavities”, describes the Academy of Medicine. “Interventions concerning the septum, the inferior turbinate and the sinuses of the face” prove to be particularly risky. In this regard, the HAS recommends oropharyngeal tests, during which the swab is introduced into the back of the throat, in the event of a contraindication to nasopharyngeal tests, for asymptomatic patients;
During sampling, check that your head is not in a "hyperextended" position, and try to keep it in the most natural position possible, "chin parallel to the ground";
During the introduction of the swab, it is a question for the specialist, or for you during a self-test, of "following the floor of the nasal cavity horizontally and in no case deviating it upwards, in the direction from the base of the skull.

In the case of self-tests, the risk is of not going far enough into the nasal cavity and therefore of taking an unreliable sample. Or conversely pushing the cotton swab too far: the gesture can then become “dangerous when the swab is too deep and directed in the wrong direction”.
