It provokes the development of tuberculosis tubercle bacillus or Mycobacterium tuberculosis, precisely because it is synthesized tuberculin - a substance that is not under- and intracutaneously administered during the Mantoux test. If a person is infected with TB, the body necessarily react to tuberculin. If the body is healthy and not "familiar" with the Koch wand, no reaction should not be. It would seem that everything is simple. But this is not the case.
The fact is, hthe positive Mantoux test is not only a sign of tuberculosis infection, but also very often (more often than you might think) it is just a natural consequence done in the hospital or continue on schedule vaccinations BCG. If the child has developed a strong immune system as a result of vaccination Mantoux test will also be positive. In this case, the doctor will prescribe your child an X-ray or chest X-rays and, most likely, it is not innocuous drugs, drink who have just for the sake of prevention - just in case.
It is in this - in a high percentage of false-positive reactions - and is the main drawback mantu
. However, not so long ago, scientists were able to eliminate it. They found and identified specific proteins of Mycobacterium tuberculosis that are not in the vaccine BCG. These substances and have become the basis Diaskintest - one more, but more efficient, modern and, most importantly, accurate skin test for tuberculosis.An earlier (in the hospital or at an older age) BCG vaccination does not affect the result Diaskintest. He then becomes positive when a person is infected with TB and really in need of treatment. Thus, a positive Mantoux test - an occasion to observe and examine the child, but if it Diaskintest negative - you can calm down, the baby is healthy, his body is not active tuberculosis infection. In addition, Diaskintest very accurate - if developed TB infection, the sample is positive with probability approaching 100%.
Application Diaskintest allows 10 times to reduce the number of children receiving unreasonably potent anti-TB antibiotics.
