All contagious diseases gets reported to HMC and Medical Commission, including the QID and phone number of the patient. If it is active, HMC will give you treatment and won't even let you board the plane since the transmission of such is airborne. Also, TB test is done via skin test, and X-ray will only show the condition of the lung.

Bottom line, either you go to private or wait for the medical test, it gets reported either way. If you don't feel any night fever, sweating, coughing with blood, etc., then you have nothing to worry, IMHO.
