I'm trying to understand my recent x-ray results which mentioned 'right apical PTB of undetermined activity.' I'm a bit concerned because I did a sputum test and it came back negative for TB bacteria. Also, I have no TB symptoms and the last time I had this disease was 14 years ago. Could this be something serious? What should I be looking out for?
The X-ray result indicates a past, likely healed, tuberculosis (TB) infection in your right lung, with "undetermined activity" suggesting no current active infection, which is supported by your negative sputum test and lack of symptoms.
