These are TB tests which can be used to determine if someone has latent TB, which means that they are infected with TB bacteria. There are also TB tests, which when considered alongside other factors, such as whether someone has TB symptoms, can confirm a diagnosis of active TB or TB disease.
A positive result does not mean that you have active TB disease right now -- the TB in your body could be either active or inactive. Active TB is bad for your health and contagious to other people, while inactive TB is not. And so, after a positive TB test, you will need further testing to determine whether you have active or inactive TB infection. A negative test result means that your system does not recognize TB, most likely because you have never been exposed to TB. After a negative result, further testing is usually not needed. AITC offers 2 types of tests for TB.
