Hello I want to tell few things about tuberculosis ( pulmonary or in lungs ) as in your case. Clinical manifestations of TB include FEVER, MALAISE, POOR APPETITE, WEIGHT LOSS & NIGHT SWEATS. In blood examination usually E S R very high. Leukemoid may occur. Cough is most common , initially dry , later on productive. Hemoptysis later on , or early symptoms. Pulmonary TB always causes abnormalities on plain chest X ray. In primary ( as in your case ) T B after recent infection abnormalities are generally in the middle or lower lung zones, oftern associated with ipsilateral hilar adenopathy. Over time there develops cavitation.. Sputum examination for A F B is an important tool in diagnosis . If sputum is not present three morning sample of gastric aspiration should be taken. Now a days NEWER technologies of NUCLEIC ACID AMPLIFICATION have been improve diagnostic speed and ability to confirm T B species. In my opinion if you have any doubt deal as for a newer method of diagnosis. However clinical examination and detail history of illness also play an important role. Hope this information will help you. Tuberculin test and Montox s test are also important tests. Good luck.
