[|Human|] Hi Dr s i would like to ask about my X-Ray result and it says there is Reticular nodular hazy densities. And the conclusion says Inflamatory process, right upper lung fields. Suggest follow clinical correlation to rule out ptb. What is this mean? Do i need to do sputum test?
[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should definitely get done sputum examination for AFB to rule out pulmonary Tuberculosis. Reticular nodular jazzy lesion are suggestive of active infection. And TB bacilli has great affinity to the upper zone because oxygen tensioning upper zones are highest. So TB Bacilli can grow easily. So pulmonary TB lesions are most commonly seen in upper lobe. Because of this fact, any upper lobe infective lesion should be ruled out for tuberculosis. So sputum examination should be your next investigation to rule out PTB.
