Tube of tuberculin test

Tuberculin tests are known as traditional studies that help determine the presence of an agent of tuberculosis in the body. This may be a Mantoux reaction or a more modern Diascinteg. And in one, or in the other case, you can face a bend of tuberculin test - a rather suspicious diagnosis. As a rule, those who do not have to deal with the problem, what they are, have no idea.

What is the diagnosis - the turn of a tuberculin test?

Each of you probably perfectly remembers about the annual mantle and the so-called buttons, which after a shot can not be drenched. The principle of this research is simple enough: a small amount of tuberculin is injected into a person, and after a few days it is estimated how the organism reacts to it. Tuberculin is a mixture of substances derived from mycobacteria. Accordingly, immunity must be neutralized. And if everything happens as expected, the "button" of Mantou remains small.

The true turn of the tuberculin test is the transition from a negative Mantoux reaction to a positive one. Its main criteria are:

• first detection of a positive or a dubious sample;
• an increase in the "button" to 17-20 mm;
• the excess of the previous reaction is six or more millimeters.

What is the true turn of the tuberculin test?

In fact, adults with tubular test specimens have to rarely collide, because after school, tuberculosis is detected only with the help of fluorography . The Mantoux reaction in adults is carried out only when:

• there is a suspicion of an active form of the disease;
• there was a contact with the infected person;
• will have BCG vaccination.

The circulation of a tuberculin test does not mean that a person is infected. Sometimes in an increased "button" they do not recognize an allergic reaction. And it happens that the turn just confirms the carriage of the infection. To clarify the diagnosis, it is necessary to conduct refining studies, to pass all the necessary tests.

Treatment of the bending of tuberculin samples

Some specialists immediately prescribe antibacterial agents. They really can be needed. But before starting therapy, it is recommended to pass a quantiferon test. This is a modern method that determines the presence of a pathogen in the body with high accuracy. If it is positive, therapy really needs to start.
