A positive TB test indicates that you have been infected with the bacteria that causes tuberculosis. There are two main types of TB tests: the tuberculin skin test (TST) and the interferon-gamma release assay (IGRA).
For the TST, a small amount of tuberculin is injected under the skin on your forearm. You will need to return to have the test read by a healthcare provider within 48 to 72 hours. If there is a bump or raised area at the injection site that is a certain size, the test is considered positive.
With the IGRA test, blood is drawn and tested for the presence of proteins that the immune system produces in response to the TB bacteria. If the results show that these proteins are present, the test is considered positive.
If your TB test is positive, it does not necessarily mean you have active tuberculosis. It simply indicates that you have been infected with the bacteria and that further testing may be needed to determine if the infection is active. It is important to follow up with a healthcare provider for additional testing and possible treatment if your TB test is positive.
