Mantoux Test

The Mantoux test is a diagnostic test that is used to detect tuberculosis. It is an intradermal injection of a specific substance - tuberculin, containing antigens of the causative agent of tuberculosis - Mycobacterium tuberculosis. The result of the test is the appearance of an infiltrate - thickening of the skin at the site of tuberculin injection.

The Mantoux test is not a vaccination and does not protect against tuberculosis, but allows you to identify the disease at an early stage, when it does not yet manifest symptoms. The test is recommended to be carried out annually, starting at the age of 1 year.

However, before performing a Mantoux test, it is necessary to carry out preparation and dietary restrictions. A few days before the test, you should not eat foods that cause allergies or foods containing allergens. For example, products with large amounts of cocoa, chocolate, citrus fruits, pineapples and other exotic fruits. You should also avoid fatty and spicy foods, alcohol and smoking. Before the test, you must make an appointment with a pediatrician and undergo an examination, as well as follow all the doctor’s recommendations.

According to the results of Mantoux's study, four types of reactions are distinguished:

1. Negative reaction - infiltrate less than 5 mm in diameter. This indicates that the child does not have a tuberculosis infection. That is, vaccination is necessary. 2. Positive or weak reaction - the diameter of the infiltrate is from 5 to 9 mm. It is believed that she speaks of infection. In this case, it is necessary to repeat the test in a month and, if necessary, contact a phthisiatrician. The doctor may prescribe treatment with anti-TB drugs. 3. Positive or strong - diameter
