montoux is not a diagnostic test , it just tells that you are exposed to tuberculosis and in countries like India , Africa and most of the developing countries almost 70-90 percent of ppl are exposed to TB and almost all medical professionals are also exposed to TB , that means everybody lol have a montoux positive in other words you can say Montoux tells the immune response not the disease diagnosis of tuberculosis disease is made only by sputum smear examination or sputum culture for tuberculsosis and never by montoux disscuss this with your physician so that he can guide you best thanks feel free to ask more questions
