Hi I took a mantoux test in 2007 for university. It was negative. However, since then the injection site reappears  as if I had just gotten the shot. It only itches, nothing serious and happens appr twice ayear. it only last for a day. Do I have tuberculosis?
Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about this. This is immunological reaction. This kind of reaction does not suggest tuberculosis. For confirmation of tuberculosis, symptoms and bacteriological diagnosis are needed. Only on the basis of manitou test, diagnosis of tuberculosis should be done. Symptoms of tub are low grade, evening rise fever, weight loss, anorexia, decreased appetite, cough, expectoration, hemoptysis (blood in sputum) etc. If you are not having any of these symptoms then no need to worry about tuberculosis. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
