The more there are in the human immune cells that can deal with the tuberculosis Bacillus, the greater the width of the seal on the arm that occurs after vaccination Mantoux. Redness around it measure is not necessary, as they are not a sign of infection of tuberculosis.
Seal in people who have received the proper vaccination in childhood, seal is a pale pink color, distinct border is missing. From an infected person, it gets a bright red pigment and clear contours. In the case of suspected infection, the patient is sent to TB.
When the doctor is unable to determine a positive test with the infection or vaccination, the skin test is done again after six months. Discovered after that the red seal larger sizes indicates infection.
To exclude a situation when the results of the sample have the symptoms of a disease due to an individual Allergy to some components of the test, is an injection with a similar solution, but without tuberculin. If you define the same reaction to this test, are the medical records of the patients hypersensitive to the components of the test solution.
Allergic diseases. It can be drug or food allergies, dermatitis. Also, the results of the reaction can influence immunity to non-tuberculous mycobacteria, age, chronic pathology.
Has the value of balanced nutrition kids, phase of the menstrual cycle in women, individual skin sensitivity. Affect the results of the samples can of worms. Influence the PPD is a harmful chemical emissions into the atmosphere of a specific region, as well as an increased radiation background.
Negative. Redness after Mantoux missing, the seal does not appear or its width does not exceed 1 mm. This reaction indicates that the tubercle Bacillus does not leak into the patient's body. The same symptoms can occur in people who have contracted for the past 2.5 months old. and patients with very weakened immune systems.
Doubtful. This is the response when the width of the seal does not exceed 4 mm.
Positive. Formed seal width 5-16 mm. the Body with a reaction to the skin test has a good immunity against tuberculosis.
If the width of the seal in a child greater than 17 mm, and an adult - 21 mm, or in the place of Commission of the shot ulcers and ulcers, the reaction is considered hyperergic. This suggests that there was a hit a large number of bacteria tubercle Bacillus in the body, and the person infected. Healthy people can have a reaction if you suffer from allergies or have recently had an infectious disease.

The types of reactions on a sample
Negative. Redness after Mantoux missing, the seal does not appear or its width does not exceed 1 mm. This reaction indicates that the tubercle Bacillus does not leak into the patient's body.
