The TB skin test (also known as the Mantoux tuberculin skin test or TST) is one method of determining whether a person is infected with TB bacteria. Reliable administration and reading of the TB skin test requires standardization of procedures, training, supervision, and practice.
A tuberculosis (TB) blood test uses a blood sample to find out if you are infected with TB germs.
There are two types of tests for tuberculosis (TB) infection: the TB blood test and the TB skin test. A positive test result for TB infection means you have TB germs in your body. If you test positive for TB infection, your health care provider will do other tests to determine if you have inactive TB (also called latent TB infection) or active TB disease.
A tuberculosis (TB) skin test can tell if you have TB germs in your body. A TB skin test requires two visits with your health care provider. The TB vaccine may cause a false-positive TB skin test reaction.
