To my knowledge.... the MedCom is only interested with OLD and ACTIVE Pulmonary Tuberculosis in your Chest Xray results. Abnormalities or any "NON-Suggestive TB", like example RTI or Respiratory Tract Infection are advised to undergo antibiotic treatment for a minimum of at least 10days. Abnormalities of "Suggestive TB" will depends on their visa type application. If they're on family visa or family visit visa (visa to join their family here),...for "Active TB" patient will immediately start the treatment and for "Old TB" patient needs to follow up at the TB Unit in Rumaillah. But for those applying for work visa,...OLD and Active TB will be automatically labeled UNFIT and deportation. But please note, I am NO medical expert here though these are some informations I gathered and would like to share.
