Why can not the mantle be wetted? Timely diagnosis of tuberculosis

Many in the childhood did a Mantoux test. At the same time, a nurse or doctor was strictly warned that it can not be watered. So why can not the mantle be wetted? The answer to this question is both simple and complex. In order to competently respond to it, you should deal with the vaccine itself.

What is the Mantoux test?

So, the main goal of the Mantoux vaccine is to check for the presence of antibodies in the body that can counteract the tubercle bacillus. After 3 days after it, doctors study the reaction, which manifested itself as redness in the place of the sample.

If the former little reddening remains on it, this indicates that the antibodies that counteract the tubercle bacillus are produced in the body. But why can not the mantle be wetted?

The fact is that after the sample gets wet, the red speck can significantly increase in size, and eventually the doctors fixing the result of the reaction recognize this as the absence of antibodies in the body that can counteract the tubercle bacillus.

As a result, you can be prescribed treatment and will not find out if you have been vaccinated or not. After all, the doctors already warned why the mantle can not be soaked.

A significant increase in the red speck from the Mantoux reaction can be caused by friction from tight clothing. Also one of the reasons why it is impossible to wet the mantle is that an allergic reaction may occur if the moisture gets into the vaccine site. The whole matter in the composition of the injected substance is tuberculin. Some components become allergenic if the skin gets normal moisture.

Who needs to do it?

Why do mantas for young children? Currently, many parents refuse any vaccines and vaccines, among them is the Mantoux test.

It is done for all children, regardless of whether they are vaccinated or not. Unfortunately, with the advent of antibiotics, the problem of treating certain diseases has not been solved. Tuberculosis bacillus is still resistant to many antibacterial drugs.

Many mothers have denied vaccinations for their child since the hospital. But they do not understand, than risk. The Mantoux sample is vaccinated to children once a year, despite the results of the previous reaction.

Once every six months she becomes unvaccinated. It is not done twice on one hand, because human cells have immunological memory, as a result of which the vaccine can give incorrect results and cause additional questions from parents and doctors.

The size of the mantle is estimated after three days. If there is a small spot on the skin, or there is none at all, this indicates that the antibodies necessary for protection are present in the body, but they are unable to give a high degree of protection.

If the size is up to 2 mm, the sample can be made again. If the red spot is within 5-16 mm, this indicates that the body can provide adequate protection against the tubercle bacillus.

Attention! Take care that children do not scratch the injection site, as it will itch!
