Thanks for visiting HCM.
TB or tuberculosis is usually diagnosed by sputum for acid fast bacilli(AFB) where bacteria is actually seen under microscope. Other suggestive investigation include lesion on Chest xray, positive montoux test (>10 mm), raised ESR etc.
The symptom of tuberculosis are cough of any type for more than two weeks, bloody sputum, loss of weight, evening rise of temperature, night sweats
etc.. Many a times especially in early phase it can be asymptomatic.
Now in your case since the xray has suggestive lesion, montoux is posotive and moreover bacteria is seen in sputum, it seems that you have got pulmonary tuberculosis
and you need treatment.
Don't worry TB is fully curable disease with a treatment of 6 months ( 2months of isoniazide, rifampicin
followed by 4 months of isoniazide and rifampicin)..
Meet your doctor to start anti tubercular therapy(ATT)....
best wishes for your health...
