Hello, I have been working for about 1 year and 8 months as a recruitment specialist, last march 2011 we are about to undergo annual medical examination and was found out that in my x-ray there's a densities in my right upper lobe, by then i have to repeat my x-ray the same time for apicolordotic view. the result is the same, for further clarification of my xray result, they asked me if i have a cold or a cough, but then i don't have any of that that time. And to clear my result they have given me 3 days to examine my sputum monitored every morning..but the hardest thing is that It's so hard to get sputum early in the morning because i dont have cold.. What am i going to do, Doc? Thank you and Godbless..
