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

[ABC2019]

Hey, I learned not so long ago that the alcohol you drink does not only go into your blood but diffuses EVERYWHERE in the body in all fluids (more or less)!

except that what you drink is not injected intramuscularly, but it goes through the digestive tract which is precisely made to pass quickly into the blood, the principle of food being to feed all the cells ....

Could you explain that to us?

Intestinal absorption refers to the passage of substances that we ingest through the walls of the intestine in order to be diffused in the body. Absorption concerns: products of digestion, vitamins, mineral salts, water.

These products thus pass from the lumen of the digestive tract to the blood or lymph:

Through intestinal absorption, sugars, fatty acids and amino acids from food pass into the blood vessels. (NB: alcohol is water-soluble like sugars or acids, so same circuit ...)


Absorption is maximum in the small intestine, thanks to the presence of folds in the wall:

The conniving valves, which are the folds of the intestinal mucosa.
The intestinal villi, which are the folds of the intestinal connective tissue.
Cellular microvilli, that is, the folds of the plasma membrane of intestinal cells called “enterocytes”.
Thanks to these folds, the possible exchange surface between the wall and the nutrients increases: it reaches 200 m², or the equivalent of the total surface area of ​​two tennis courts!

No, not the copy / paste that everyone can do, what do you think.

What do you mean by “quickly”? I'm talking about the food.

we were talking about alcohol. Quickly, that's how long it takes you to feel cheerful after a few glasses of wine. Has it ever happened to you? well try, you will know like that ...

In fact Bozo is not Bozo ... It is Garcimore!

Because he has the art of making arguments disappear which does not suit him !!

You are told that any poison in the blood is quickly (a few minutes) diffused throughout the body! So this is the case for vaccines too!

Your argument that the components of the vaccine would remain in the muscle at the site of the sting is the asshole unless the lifespan of the compounds would be only a few seconds which is probably very wrong!

Do you have something to hide so that the vaccine doesn't go all over your body or what?

So what's the title of the subject? Let's crop gentlemen!

You too should try it's much faster than that! It's not a few drinks: it's a few seconds after the first drink!

Alcohol passes (in part) into the blood already in the mouth under the tongue! Like some drugs (which must let melt without the mouth) ... disappointing not to know that from you!

good after checking, we are both partly right and wrong:

you're right, the vaccine diffuses well in the body after an intramuscular injection (less quickly than intravenously but still)

I'm right, the vaccine does not cause a positive reaction to the antigenic tests, on the one hand because the proteins are not found in the mucosa or in small quantities (and the antigenic tests are not very sensitive, in fact they are blamed not being sensitive enough), on the other hand because many tests test other proteins than the S protein in the vaccine.

Good bin there! There we advance! Thank you ! But there is still a risk because:

In addition, only a few antigenic tests (WHICH?) Limit themselves to detecting the antigen used by Covid-19 vaccines (the Spike protein). The risk of a false positive linked to vaccination is therefore virtually zero.

A few bin is not nothing! Finally!

If you have the full article or some other open source, I'm fine!

If it's technical details of rapid antigen testing that you want, there you go.

The test kit contains a nitrocellulose (NC) membrane coated with the rabbit anti-S1 protein of novel coronavirus antibodies in the T-line region, and the goat anti-rabbit IgG polyclonal antibody in the region. of the control line (C). The latex labeled ACE2 protein and the latex labeled rabbit IgG are incorporated into the reagent buffer.

To perform the COVID-19 (Latex) antigen rapid test, three drops of the sample are added to the sample well and the sample flows from bottom to top by capillary effect. After a 15 minute incubation if the patient sample contains a virus, the latex labeled ACE2 protein will be bound to the S1 protein of the virus and then captured by the anti-S1 protein antibodies coated on the T-line region. If the sample does not contain virus, the latex labeled ACE2 protein will not be captured by the anti-S1 protein antibodies coated on the T line region, so no T line will appear. Whether or not the sample contains a virus, the latex labeled rabbit IgG will react with the polyclonal anti-rabbit IgG antibody coated on the control line region (C) and a colored line will appear in the control region.

Once the test is complete, the amount of latex-ACE2 protein bound to the T line is directly proportional to the concentration of the novel coronavirus in the sample, while the amount of latex bound to the control C line is not correlated. to the concentration of coronavirus in the sample. https://www.mmbiotech.it/fr/prodotto/te ... -joinstar/

Personally, the goat anti-rabbit IgG polyclonal antibody I don't know what it is.

But I know that these tests are not very sensitive and need a significant number of antigens to be positive (a real infection, the vaccination being only simulation to cause the antibodies). There are too few antigens from vaccination, especially in the mucous membranes. No reaction with rabbit antigen

Self-tests are antigenic tests. To authorize these tests, the Haute Autorité de Santé requires that their “sensitivity”, ie their ability to detect the virus in a sick person, amounts to at least 80%. Their "specificity", ie the probability that a person who tests positive is actually a carrier of the virus, is over 99%. The risk of a “false positive” is therefore extremely low (less than 1%).
