Tuberculosis is tested with a skin test. A small amount of the tuberculosis bacteria is injected onto the forearm. This test does not hurt but leaves the skin with a series of little pricks. If the person does not have TB or any TB bacteria in their body, the pricks will quickly fade away within a few days.
If the person has TB, the skin around the tested area will become inflamed. It will become inflamed because a person who has the infection will be sensitive to the bacteria.
TB is a disease caused by the bacteria, Mycobacterium Tuberculosis. TB was once a major cause of death and the biggest killer in the US but since the invention of drugs to treat and prevent TB, it is no longer such a threat. TB is spread through the air and usually spread when a person who is infected coughs or sneezes and another person breathes in their bacteria.
People can also have TB in other parts of the body, such as the kidneys or spine, but this is not normally infectious. It is possible to carry TB but not be affected by the bacteria. It is unlikely that a carrier of TB will know they have the disease but will spread it to other people, this is why the TB testing is so important.
