[|Human|] Hello sir,am 25yrs old,i had a history of tuberculosis 4 yrs back I took 9 months treatment and repeated my chest xray it was normal,recently while undergoing a medical check up for gulf country my Xray showed opacity of right hilum,but my PPD TEST was negative am really worried,will my old TB scar heal?
[|AI|]  Howell come to ChatDoctorI really appreciate your concern, if you have completed the course of tuberculosis then it may not be any lesion detected in x-ray if this is so then it may be resistance case of tuberculosis, and it has to be taken under consideration PPD test is not specific one for any decision, better to get done the repeat x-ray, it is highly requiring differentiating the lesion from tuberculosis, hope this information helps.
