The fourth component of a complete TB medical evaluation is a chest x- ray. A patient should have a chest x-ray if he or she has a positive IGRA or TST result or has signs and symptoms of TB disease.

 

The chest x-ray will usually appear abnormal when a patient has TB disease in the lungs. It may show infiltrates or cavities.
