[|Human|] Hello! Im 18 years old and recently I just had a Chest PA. The findings were: hazy and streaky infiltrates seen in the left upper lung field. The rest of the lung fields are clear. The impression was: Left upper lung TB, activity undetermined. Im somewhat confused since I dont have a known history of TB and during and prior to the test I dont manifest any of the common signs and symptoms of TB such as cough for more than 2 weeks. Please clarify me with my condition if I really have TB now. If I do have, what should I do? Thanks.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Your x-ray findings are more in favor of tuberculosis. Tb infection is most commonly seen in upper lobes. Actually tb bacilli grow more in upper lobes due to high oxygen in upper lobes. So any infiltration in the upper lobes must be first investigated for tuberculosis. So possibility of tb is high in your case. So consult pulmonologist and get done clinical examination of respiratory system, sputum examination for AFB (acid fast bacilli-bacteria causing tuberculosis), CT thorax and bronchoscopy if needed. You may need anti-tubercular Chat Doctor.  Minimum duration of 6 months is required. So better to first confirm tuberculosis by above-mentioned investigations and then start appropriate anti-tubercular
