How do you know if you have latent TB?
The main ways to diagnose LTBI are by placing a tuberculin skin test (TST) on the forearm or by getting a TB blood test, in addition to obtaining a chest radiograph (x-ray) if either one of these tests is positive. One-third of the world’s population has LTBI. The TB germs are dormant (asleep) in the body.
What happens if you test positive for latent TB?

What test result will show that you have tuberculosis bacteria in your body?
There are two kinds of tests used to detect TB bacteria in the body: the TB skin test (TST) and TB blood tests.

It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease.
