<human>: Hi!recently I applied for uk student visa,they required to go through a tb test before arrival. So I went to medical center first they took a chest X-ray but there was a shadow in center of my chest but not on lungs so they asked me to go through a sputum culturing test,but im worrying about that although I have no any symptom no cough no sputum no fever nothing, I never smoke,and never did any thing that can cause tb,but I heard that culturing can find even a very miner bacteria,so is there any chance of positive report?and is there any other test where I can examine myself with detail about tb bcoz I dont wanna waste my 42 days,
