<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello online doctors. I recently diagnosed with Pulmonary Tuberculosis. I had my Chest Xray done with infiltrates right upper lobe. Impression: Pneumonia vs PTB. The doctor advised me to take 10 days Levofloxacin then repeat CXR. Still no changes. I had my GENE Xpert done whicChatDoctore out negative. I don t have any of Tuberculosis symptoms. So what I did is consult a Pulmonologist. After seeing my CXR she immediately diagnosed me with PTB. I told her I don t have any symptoms and I feel healthy. My Gene Xpert is negative. She replied to me saying that Gene Xpert are only 50 accurate. So she took her prescription pad and wrote down TB meds that I should take for 6 months. I am still in a state of denial. Eventhough I am not really convinced, I still started the TB meds for a week now. Is this how doctors diagnosed patient with Tuberculosis? Do I really have TB? Am I misdiagnosed?  <response>: Hi, As per the recent WHO guidelines, the diagnostic criteria are multiple levels and beyond complete scope of this online platform, but still, I am narrating salient features herewith to help your case. Tuberculosis diagnosis firstly must be confirmed via microscopy such as sputum, gene expert, lymph node biopsy or else when X-ray chest is normal or inconclusive. Supportive data of symptoms as weight loss, persistent fever, anorexia, cough are vital co relations to be considered. The response to primary treatment of underlying pathology and its regular evaluation on periodic basis is the foundation of giving trial anti-tuberculous treatment. As per my clinical experience, I would say you to take second expert opinion with a pulmonologist. Hope I have answered your query. Let me know if I can assist you further.
