Diaskintest is the norm

As is known, Diaskintest is used to diagnose tuberculosis mainly in children. The agent is injected intradermally, after which, after 72 hours, the result is evaluated. Normally, there is no reaction to Diaskintest, or the size of the papule, the hyperemic area of ​​the skin, does not exceed 2 mm. In healthy children, in most cases, after the test, only a trace from the injection remains.

How is the result of the sample evaluated?

Evaluation of the result is carried out by measuring the size of the skin reaction, using a conventional ruler. Therefore, this test can not be called highly informative. However, due to the lack of an alternative, this method of diagnosing tuberculosis is applied in practice in all health facilities.

How do you determine the result yourself?

Any mother, without waiting for a visit to the doctor, can independently determine the result of the test. To do this, you just need to know how to measure correctly, and what Diaskintest's negative result looks like.

As already mentioned above, in norm, after the spent test for tuberculosis Diaskintest, the reaction to the surface of the skin should be absent. In practice, this can be observed only in isolated cases. Therefore, even with a slight redness, but no swelling, the result of Diaskintest is recognized as negative.

If, on the site of the sample, after 3 days, the mother discovered a small infiltrate or a papule, this means that the result is positive. In no case should not panic. In such situations, the doctor prescribes a second examination after 60 days. In addition, such a diagnosis can not be made by the result of a single sample. If suspected of tuberculosis, an X-ray is performed that confirms or refutes the alleged diagnosis.

It is not uncommon for doctors to say that the results of a Diaskintest performed by a child are normal, while a bruise remains at the injection site. This fact is explained by the fact that during the puncturing of the skin, quite often the needle injures a small blood vessel. As a result, at the injection site, after a few hours, a small hematoma forms. Therefore, Mom should not worry because of this - the bruise will disappear after just 3 days.

Diaskintest can be negative in the presence of tuberculosis?

Negative Diaskintest does not mean that the patient is healthy. A similar result can be observed in those who have already cured this disease, or in children who are affected by an inactive form of tuberculosis. It is this fact that makes it difficult to timely, early diagnosis of pathology.

Also, a negative reaction to the administration of the drug can be observed in those children whose disease is in the stage of completing tuberculosis changes. It is because of this that absolutely all signs of a pathological process are completely absent. In addition to the above, Diaskintest can be negative in those children who are sick with tuberculosis , but have various kinds of immunopathological disorders, which in turn is caused by a serious course of the disease.

Thus, after the Diaskintest results, the results are recognized as normal if there is nothing at the injection site other than the injection stick. However, parents should not panic after they find on the surface of the baby's skin a slight swelling or redness on day 3. Only a doctor can draw conclusions from the results of the analysis.
