This is why chest x-ray is the next screening test for people with positive TB skin test. However, people with active TB usually have other symptoms like fever, chills, night sweats, weight loss, cough, shortness of breath, cough up blood, ect.Current recommendation is that you should take INH (antibiotic) for 9 months if you have positive TB skin test. This is because you may carry the TB bacteria within your body somewhere even though they are not causing any active disease. Chest x-ray will be your screening test from then on because you will be positive again with future TB skin test.
