I am diagnosed with ptb both upper lobe undetermine. i already finish my 6 months medication. what does ptb both upper lobe with regression mean?

Pulmonary Tbc: I suspect you are referring to inactive pulmonary tuberculosis. The 6 mos. Is usually with Isoniazid alone and is designed to prevent or reduce the chances of reactivation of active disease. Do not know what they meant by regression, but once you have tbc bacilli in your lungs, the possibility they will become active infection exists and the risk of this is reduced by treatment with inh.
