Hi doctor,

I have done a left BKA (below the knee amputation) due to an automobile accident. I did a TB skin test recently and the result was negative. I had an IGRA (interferon gamma release assay) for work because I did not have enough time for a two-step and was positive. I had an X-ray done and the impression was no evidence of acute cardiopulmonary disease, communicable disease, or active tuberculosis. I am currently taking certain vitamins, and tablet Metformin 100 mg twice daily, and my blood sugar level is under control with a proper diet. Should I get treatment for the latent TB infection? Can it be done online? After treatment, would the TB vaccine be appropriate? Please help.

Hi doctor,

Thank you for your reply. I had no symptoms. I do not have fever, cough, and weight loss. I do not smoke and rarely drink. Maybe four or five drinks a year. I do not recall seeing anyone symptomatic when I visited the other country. However, I did go to a couple of resorts. I went to the mall, several site seeing tours, ate at restaurants, and in public. If I saw anyone coughing, of course, I would go the other way. But droplets, I could have gotten on my hands and you know how it goes from there. Please help.



Welcome back to

I understand your concern.

So you need not worry about this positive test. If possible get a TB (tuberculosis) vaccination before revisiting. I would suggest you get a CT (computerized tomography) thorax (lungs). Because sometimes chest X-ray cannot pick primary complex if at all you have. TB affects the lungs first by showing primary complex. The primary complex is difficult to pick up by chest X-ray. So CT thorax is needed. Is it possible for you to undergo a CT of the thorax? Please reply to the above-asked questions so that I can guide you better.

Wish you good health.
