my question is I took a chest x ray before a month, the result shows some kind of white things on the bottom of my right lung, the doctor send me to test TB.  I dont have any kind of symptom TB like cough, night sweat and any other smymptom.  Still I am waiting the result it will take 9 weeks to know the result.  would you please advise or tell me the possiblity of being TB positive without any symptom of TB?
Hello ! I can understand your concern.  If you are completely asymptomatic and doing healthy then it is quite unlikely that you will have TB.  Not all white things on an x-ray are Tb. Sometimes even twisted positioning of a normal person while taking x-ray will cause white shadows in the x-ray, which can be misinterpreted as abnormal if we fail to realize that it's rather the rotation of the patient and nothing abnormal. Likewise, if you have not taken a proper deep inspiration while taking x-ray too, there can be white shadows in the lower portion of lung.  These are just examples to tell you how even a normal person can, due to technical errors while taking x-ray, land up with abnormal shadow on x-ray. So first thing I would suggest is you review with your physician/ radiologist and discuss again. If in doubt and clinically indicated, you can get a CT chest done to see what the white thing is all about.  Hope this helps.  Do Chat Doctor.
