that will be the decision of the medical officer who will sign your medical evaluation in Philippines. it is not about u being filipino (lol) or a graphic designer (c'mon!). it is about a pulmonary scar. the health policy of Qatar is that pulmonary scars indicates having had contracted a disease. the bacteria may be dormant in your body, and therefore poses a potential threat.

even if your medical exam in Philippines, you would still be required to take a chest xray here, and if found with this scar, you may be sent to the health center where they will test you further, and most probably give you prophylactic treatment. i don't think they will send you home.

the thing is that the medical centers in Philippines are very strict with this, because if something went amiss, they will be held liable for passing somebody carrying this bacteria, however dormant.

hope that helps.
