Timely diagnosis of tuberculosis is extremely important for the treatment and saving the patient's life. The complexity of the diagnosis is that the disease has many forms, which can manifest itself in a wide variety of symptoms. That is why, in the process of diagnostics, one cannot do without special studies.

Step 1

Mass tuberculin diagnostics (Mantoux reaction) is the main method for detecting tuberculosis in children and adolescents. A nurse administers tuberculin intradermally, and after 72 hours assesses the individual response to the drug. At the injection site, an infiltrate (papule) occurs, the size of which is much larger in infected and sick individuals. The papule is measured using a transparent ruler. In the absence of papules or with slight redness of the tuberculin injection site, the reaction is considered negative. In this case, additional diagnostics are not needed. A papule larger than 5 mm is interpreted as a positive normal reaction. When the size of the infiltrate is more than 17 mm, the reaction is considered pronounced. In the latter cases, a thorough examination of the child and consultation with a phthisiatrician are necessary. Evaluation of the result in dynamics is of great importance. Bend (a sharp increase in the size of the infiltrate compared to the previous year) indicates that the child was infected with tuberculosis and has non-sterile immunity. In this case, additional examination and chemoprophylaxis with isoniazid are indicated.

Step 2

Diaskintest is a new accurate method for detecting tuberculosis. The technology of its conduct is identical to the technology of the Mantoux test. The reaction is also assessed after 72 hours, but a positive response (swelling more than 5 mm) most likely indicates the presence of tuberculosis.

Step 3

X-ray methods are widely used to diagnose tuberculosis among the adult population. Fluorography and X-ray examination can show changes in the lungs and suggest tuberculosis.

Step 4

The bacteriological method of diagnosis is the main one for suspected tuberculosis (if the disease is suspected on the basis of previous research methods). If the sputum analysis reveals acid-fast mycobacteria, which are the causative agents of tuberculosis, the patient is diagnosed accordingly and treatment begins.
