When we put a tuberculin test in the school (she is also the Mantoux reaction), each time they did not forget to remind you: in no case should you wet the injection site. Have we been deceived all this time?

There are two varieties of tuberculinodiagnosis: a test of a feast and a more well -known and modern Mantoux reaction. Both are aimed at checking the stability of immunity to the pathogens of tuberculosis, but the test methodology is different. The Pirk test implies the Scarment - applying a small scratch to the skin through which tuberculin is introduced into the body. When conducting the Mantoux reaction, the solution is administered under the skin, and then They ask not to wet This is a place.

Several myths are connected with the Mantoux reaction. For example, from the moment of administration of tuberculin to measuring the size of the “button”, you can’t eat sweet or take anti -allergic drugs. But, of course, the most common is the inadmissibility of water entering the skin area where the injection was made.

Apparently, this is due to the fact that the Pirka test - a more obsolete technology - meant the scratching of the skin and it was precisely in the scratch that the liquid could get. Therefore, patients were asked not to wet this place. How Notes Dick Menzis, a researcher at the McGill Medical Center in Canada, can wet the mantu 15 minutes after the injection. You need to be careful after you wash your hands or took a shower: a area of the skin on which the test was carried out cannot be rubbed, so it should be carefully wetted with a napkin or a soft towel.

Foreign colleagues are supported by Russian experts. In 2018, the main Tisator (that is, a specialist in the diagnosis and treatment of tuberculosis) of the Ministry of Health of Russia She saidthat entering the skin of water does not affect the result of the study. Anna Vasilieva said: “You can wet it, then just get wet and that’s it. <...> With a breakdown, everything is not so strict - you just can’t irritate the skin. ”
