Hello Lybrate User, Tuberculosis (TB) is a disease that is spread through the air from one person to another. When someone who is sick with TB coughs, sneezes, speaks, people nearby may breathe TB bacteria into their lungs. 1) Tuberculin skin test (TST), 2) Chest X-ray, 3) CT Scan are the confirmatory test for TB.

By xray chest we can suspect TB but can not confirm without AFB demonstration in sputum by smear, genexpert mtb/rif or culture for TB mycobacteria. By mantoux test or TB gold blood test we can detect latent TB which mean one is infected with TB bacilli but can not confirm active diaese.
