Lung PTB Residuals



Ten years ago I was infected by tuberculosis. It was treated and had undergone a medication for a year. I had my lung X-Ray recently as prerequisite for my job. It has a findings of Upper Lung Minute Nodulocalcification and an impression of Lung PTB Residuals. Does it means that I am still infested with the disease and possibly contagious? Please explain. Thank you.


In order to answer the question of whether you are still infected with tuberculosis and whether you could be contagious to others, you will have to go see a physician. It would also probably be helpful to have your current chest X-ray compared to any other chest X-rays you have had taken previously.
