hi ..
you mentined TB test positive; but be sure it should be positive only by molecular (PCR) methods and molecular methods are investigation of choice.
regarding antibody estimation is not that significance as that of PCR because of cross reacting antibody and false positive reaction

Pulmonologist Dr. Shashi Dangwal's  Response
These are the serological tests for TB. They are generally not used in isolation to diagnose TB. They may be positive even in an old treated case of TB or if a person has been vaccinated with BCG or in case of infection with a group of organisms called MOTT. Do you have any symptoms like fever, cough, weight loss, malaise etc. Best course for you is to consult a pulmonoloigist who can examine you in detail and then order relevant tests to arrive at a diagnosis.
