2 years ago i've been diagnosed of a minimal ptb and undergone 6 months treatment. now that we had our annual check up include xray the result was still the same. help me!!! was this contagious? can you explain what is minimal ptb is?

No such thing: A chest Xray typically lags behind a persons clinical status when referring to TB. I'm assuming from the induced sputums they did on you..that they had sensativities to the bacilli. Therefor it should be gone. There is no such term as minimal pulmonary TB. It needs to be 100% gone..there no acceptable minimum. You won't be contagious to anyone at this point either.
