If a person has a positive TB skin test or (IGRA blood test) other tests are needed to see if a person has active TB disease. If a person has TB disease in the lungs, the bacteria can also spread to other people. Screening for TB disease usually includes a check-up by a health professional for signs and symptoms of active TB disease, a chest x-ray and sputum collection.
