Right now Mantoux test had been done in almost 40 hours there is no visibile change in the skin. Please suggest... thanks ! [/INST] Dear Sir/Madam have gone through your query and read your symptoms. In my opinion, your symptoms are an indication of a chronic infection, and in our setting in Indian subcontinent it would have been diagnosed as Tuberculosis, I would recommend you to talk to your doctor regarding this and get TB gold test done to see if this comes out positive. Other such infection include atypical mycobacteria, acidosis, etc hope that answers your query. If you want any more clarification, contact me back. </s>
