So i want to know what's going to be further process as i have done upfront medical examination and there was a scar in my chest x-ray they contacted me after a week so that i need to test my spuctum and they collected my sample now what will happen if they don't see any T.B in my sample will i be pass in medical test? and also they said they will take next x ray of my chest after 90days however the scar on my lungs will not be erased beacuse i was suffering from phonemounia in my childhood? Do i need to go under medical treatment again?
