A test that shows positive for Tuberculosis could appear in different ways. It may be that the test reveals latent TB. This would show as a hard red bump. The bump would develop where the injection was administered. This should appear within 48 to 72 hours of having the test. If the skin reaction is very severe then a chest X-ray may be necessary to determine if there is an active TB infection.
The injection is for a test called the 'Mantoux Test'. An injection of PPD Tuberculin is given just under the skin. This is done in the forearm of the patient just below the elbow. It is likely that there would be a stinging sensation for a few moments following the injection. After a few days, a check up will be given to look for a reaction to the test. It is possible that a positive test could simply be revealing the presence of TB due to a BCG vaccine given to the patient previously.
Tuberculosis is a bacterial infection spread through minute saliva droplets that are sneezed or coughed by an infected person. Someone could become infected, but their body usually fights back the infection and they would be fine. A latent infection is where a person is infected, but their immune system creates a barrier around the bacteria so that it cannot do any damage. The body cannot destroy the bacteria, but there should not be any ill effects.
Active TB is where the immune system is unable to destroy or contain the bacteria and it begins to attack the body. This usually occurs in the lungs. Latent TB can become active TB, particularly if the immune system is threatened.
